That saw is a job site saw. its small. Its also made for the european market (220 volt) and falls foul of a european health and safety law regarding how quickly the blade stops after the power is switched off. A dado set is so heavy that without a brake fitted the blade will spin for a vey long time on shutdown, so the arbor is not made for dado sets. Any conversion you might come up with is likely to be risky regarding local laws (dont know phillipines law)

 

I just hate it when someone comes up with all the right answers.

 

Sometimes some answers are not all the right answers

 

Sometimes (just sometimes) you ask a question of the right person at the right time . I am English, I have the earlier DW745, and know that the slow down rules made de walt stop making the 745 for this very reason.
If youre building a workshop, get a table saw. But..... having said that, Its quite easy to make a dado on a contractors saw, it just needs a sled and several (many) cuts. If you want a really sharp dado cut, find a Flat Top Grind blade.

 

+1 Putting a dado blade on a job site TS is not recommended.
Especially on those jobsite tools designed for EU market, with arboir speed control, or blade stop; safety features.

Philippines wood working tools?
BTDTGTTS as a former expat. Trying to find typical wood working tools similar to those sold in USA, while living in the Philippines (PH) can be a daunting, but not impossible task.
To reduce the size of this post, let me use some spoilers...

Spoiler: Wood working power challenges in PH (click for more information).

PH residential AC power grid is 'declared' as 220v 60hz, with single phase and 3 phase options. In practice the measured voltage is usually closer to 230/240v. Most industrial operations have 400/415v or 480v feed supply. If the supply voltage hovers near 240/480v, likely have delta 3PH feed supply. When supply voltage hovers lower near 230/415v, likely have a WYE 3PH feed supply. Many WYE supply systems offer 208v power. Only in older residential neighborhoods, or overload multi-family dwellings; with inferior reliability, will you see a steady 220v.

The standard 2 prong 110 volt American NEMA 5-15 or 5-20 plug is identical to the "standard" 220 volt Filipino plug; which creates confusion for USA visitors as PH does not use the NEMA 6-15/20 interconnections. There is no 110v 1Ph power in PH, without a local transformer. The 220v 1PH power source is supplied via one hot, and ground. I.E. Can not split a 220v phase with neutral to get 110V supply. Residential homes are seldom provided sufficient power for a serious wood shop; unless you live in a "mansion", "castle", or very new large home: with every possible electrical convenience (which often has a 3 phase panel).

The PH power grid is generally unreliable with wide range of voltages possible (190-250v), with large spikes being common. For sensitive computerized devices, without external supply protection allowing wide voltage variation; often need to buy a automatic voltage regulator (AVR) for devices imported from USA. Things with lap top with a regulated PS work fine; but a desktop PC power supply often has challenges with horrendous and common power spikes, needing a separate AVR.

Housing locations inside "government supported" industrial areas have more reliable and consistent power; to ensure industrial production is not interrupted. That said: All of the facilities (10 total) I work with in PH: had separate standby generators with large fuel resources for each buidling; to allow running for 2+ weeks without grid power and without additional fuel supply. When a Typhon hit near a factory, it was not uncommon to have employees temporily living in any spare warehouse space at the facility; to ensure they could come to work each day. Even some company manager's would use on-site apartments. The senior managers that didn't stay on site, had generators at thier residences.
Yes, AC power regulation and supply in PH is THAT bad.

The only good news is that large motorized power tools are generally tolerant of spikes and voltage changes with little change in performance. Hence, most any 230/240v motorized wood working machine will operate without any issues. Even 50Hz motors can be used, as long as they have adequete cooling and you can tolerate ~15% higher spindle speeds.

Spoiler: Finding stationary wood working tools in PH (click for more information).

First, PH is a poor country, by American standards. Have seen several small commercial furniture mfg using DIY gasoline powered saw blades, mounted to a wooden table, as a table saw. A home hobby shop is often nothing more than a few powered hand tools on shelf; not a shop full of stationary equipment. Anyone spending large sums on wood working power tools is generally doing so to make money, not for a home hobby. Several mfg have released clones of Festool containerized tools, for portable work; and these Festool clones are considered high end wood working tools by hobbyist. I.E. Rare to see large stationary tools in home hobby shop.
Large stationary tools are primarily found in mfg businesses, and are considered INDUSTRIAL or COMMERCIAL power tools. The only 'large' wood saws you will typically see in a "store" in PH will be: small job site TS, or portable 10"-12" BS. To find large stationary tools: need to be visiting the industrial tool distributors, not "retail" sellers. These industrial sellers typically do not have a show room. They sell by catalog, with orders shipped direct from mfg warehouses; after purchase. If you want to see one of these tools, they often have existing customers that received large discounts and allow prespective customers to visit a working shop and see the tool in person.

PH is relatively close to both Chinese and Taiwanese wood working equipment suppliers; that are sold using constantly changing regional and "Asian" brand names. Large global brand names, such as: Bosch, Dewalt, Makita, and Metabo; have local assembly factories in PH and strong local presence. Many of these local mfg even offer mfg seconds outlet. Can also find employees using the employee discount to sell tools out of thier home/car. There are also competing local mfg that sell clone colored tools of big brands; as OEM like to change suppliers every few years to keep costs low, and foster price competition. I.E. the market is flooded with huge assortment of uncommon (to USA) brand names.
As a side note: Fillipinos often think Chinese made stuff is lower quality than locally made, and prefer Taiwan tools over Chinese.
IME - the quality level for PH and Chinese clone tools is about same.

Been a few years since I was tool shopping in PH. A quick WWW search shows that OAV (Taiwan) and ChampFond (Taiwan) still both sell stationary table saws into PH with many 'wholesale' tool sellers. OAV is still offering the age old stamped steel base 12" contractor TS made popular by MaoShan (Taiwan) and sold by many US OEM during 1970's to ~2000. Owned a Mao Shan 12" contractor TS when I lived in PH. Champford PH sales appear to be mostly the larger 12" cabinet TS, similar to Venerable Delta 12/14 industrial TS. Both of these tools could use a dado blade. Can also find the Finish company Einhell, selling a bare bones TS-315 12" 'table saw' in PH, using the 'Torq' brand.

Many large industrial EU mfg like; Felder and Beckoff; have local sales offices in PH. Norde International is large mulitple industry equipment importer that represents several wood working equipment suppliers for PH. Universal Sales Corporation used to be a distributor of misc industrial wood working equipment, but it appears they were bought by Rexim, and web presence is disjointed right now? LSS Philippines is large distributor of equipment to education institutions, and offers industrial wood working tools to schools. Was able to get some Powermatic tools inported into PH using LSS, when I needed to set up a mold pattern shop in PH two decades ago. Buying tools from any of these distribuitors requires catalog shopping, and face to face sales visits.

Thanks for reading to end.

Best Luck.

Cheers!

 

In addition to a dado stack, I also have a single flat top grind (FTG) blade that works well to make square cuts in multiple passes. Consider buying an FTG ripping blade and using multiple passes. I assume that ordinary rip blades can be found in the Philippines.

If box joint sets are available where you live, they can make a flat top cut with a wider kerf. I assume that your Dewalt saw can use a two-blade set, even with the short arbor.

There are certain dado cuts that I won't make on the table saw. Examples include dados across the ends of long boards. It is too difficult and dangerous for me to cut a crosscut dado on my table saw with a long board perfectly registered through the cut.

-> Some people make special sleds for those long board crosscut dados, but I use a guide jig and a router.

Look at your router situation. Consider making dados using routers instead of the table saw. A combination of a handheld router and guide jigs and clamped straightedges can make good dados. Add a decent router table and you would have extensive woodworking capabilities. Either or both can eliminate the need for a dado stack or FTG blade in your table saw.

 

I moved from the US to eastern Europe with my shop. I use step down voltage converters for most of my tools (vintage Rockwell/Delta) but plan on repowering a few if them that have seperate motors.
Can you order a dado from the US? Or have one bored out to 1"?

I run siamesed tablesaws, the right side is a dedicated dado, theres also a 1/4 and 1/2" routers that all use the same fence.

The long board dados mentioned above (like shelving) I just slap the dado in my radial arm saw. The dados in that outfeed table was a router though.

If you live in the US, you can buy dado stacks with 1 inch bores from several manufacturers. I just looked at two that I like, and both offer them, although one has an extra fee for the one inch arbor hole. There are many others that I did not look at that probably offer them too. When you order, be careful to check the arbor size, but I found several dado stacks with one inch arbor holes in 8 and 10 inch sizes.

The question I cannot answer is how a person who lives in Eastern Europe would order a dado stack from a company in the US, pay for it, and have it shipped to them through their country's customs and import duties. There may be export restrictions from the US to certain Eastern Europe countries. The obvious one is Russia. I do not know about other countries such as Belarus. I do not know whether Eastern Europe NATO countries are handled differently from one another. These are the kinds of questions where local experts near you are likely to have the best answers.

You may also want to ask the manufacturers or sellers if they have experience sending products to your country and what is required. If one manufacturer won't do it, another one might.

 

I am also in the Philippines, and got the 7492 from Gigatools a couple months ago. I like it! Be aware that it is larger than its American sibling 7485; the table size as well as the blade diameter. I have built a rolling table for it, similar to the one from the Bear Mountain Builds guy (search YouTube), and had to layout my own version of it because of the different size. But all went well.

The information about the 1" arbor is only partly correct The arbor itself is a standard 1 1/4" x 5/8", as Americans are used to. The thick washer (flange) has a shoulder that provides centering and diameter for saw blades with 1" bore. Probably the most economic solution, so the arbor is the same in US and the rest of the world, just the flange is swapped (25.4 mm here in Asia, 30 mm in Germany). To mount a dado stack with 5/8" bore, just flip the flange around, so the shouldered side is facing the arbor nut. The arbor threading is well equipped to securely mount a dado. It still protrudes 1/2" when a regular saw blade is mounted. Bear in mind that you will need to make custom table inserts.

The motor brake is not instant, true; however, I do not share the concern mentioned in a precedent message. Surely the 7492 is up to safety standards when used with regular blades, since it is also sold in Germany. DeWalt does not communicate a full-stop time, but it is expected to be in the range of 3-5 seconds. (I could time mine tomorrow.) A dado stack is indeed heavier than a saw blade, but not by much, considering that its diameter is smaller than that of a 10" blade.

The Freud SD206 (6" diameter) is available at Lazada for P8K, but shipping it for free from Amazon US is just $80. PH still allows "de minimis" imports I guess I will order that soon for myself. 6" should be quite sufficient, since the 6" set will allow for 1" cutting depth, and dados are rarely that deep. The smaller the diameter, the lesser the rotational inertia.

[Update] I just asked Gemini about a very coarse estimate, and its conclusion was:

Even with higher mass, the rotational inertia of the 6′′ dado set is dramatically lower (about 36% of the 10′′ blade, before accounting for the mass increase).
10′′ Blade Stop Time (Estimate): 3 to 5 seconds
6′′ Dado Set Stop Time (Estimate): 1 to 3 seconds
The lower rotational inertia from the reduced diameter has the dominant effect, leading to a quicker stop.

Best,

It's great to know that there are a few expats here in the Philippines. I've seen the Bear Mountain YouTube video, as well as others, and I'm reasonably certain that one of them will be the model for whatever I finally decide to build. How did you get your DeWalt shipped ? I have used Lazada and Shopee for loads of small things, but never for anything heavy and bulky.
Thanks for all the information about the arbor. I won't make any decision about a dado until I can get the saw and see where I stand.

Much obliged,
