Topic tags/keywords: question brad point bit grizzly

I have a 3/4 inch brad point bit I use for a craft project. In building my new workbench I needed 3/4 inch holes in the top for bench dogs. I grabbed my bit and went to work; unfortunately I hit a hidden nail and dulled it. So I am in the market for a new bit As I was checking various sites I found that woodcraft: had one for $19.95, Rockler one for $18.39. Then I found that Grizzly has a 6 bit set (9/16, 5/8, 3/4, 7/8, 15/16, and 1 inch) for $20.95

Has anyone used the Grizzly set? How long do you think one of these would last if you drilled 20 holes a year?

Have you tried sharpening your dulled bit? I bet it can be done.

runsWithScissors, yes I have tried sharpening the bit with a file. It worked a little bit better but not good. I probably will get a friend from church to try sharpening it. Worst case I will need to replace it which brings me back to the original question. Anyone have any experience with the Grizzly set? Or more general How good are Grizzly brad point bits?

Jesse, with prices that close, it is unreasonable to discern the best buy. It would take a serious spate of testing with consistent feed rates, various densities of wood and so on, to determine what is superior to what. And in the end? My guess is, “Not Much.”

My input is the cost of shipping added to the price should help you determine which one you order.

I Googled “sharpen brad point bit” and got a number of good looking hits including this one.

With the right file—much cheaper than a new set of bits—and light pressure and counting strokes and knowing what surface to dress, it’s worth a serious try.

Kindly,

Lee

A smidge more than the Grizzly but worthy of consideration is the Lee Valley HSS brad point bits.
http://www.leevalley.com/US/Wood/page.aspx?p=42247
In my experience they cut a MUCH cleaner hole than any of the others I have tried and are custom re-ground to brad points from high quality american made drill bits. I have a cheapo set I use for <other> but when I need a clean and accurately sized hole these have become my goto bits.

I’m not sure how much the quality of the cut and hole size matter for your projects though. In practice at 20 cuts per year any of those bits are going to last a really long time. The longer bits like the Grizzly will have more run out than a shorter bit which will wallow the hole out of round a smidge so take that into account as well.

I’ve never bought a set of brad points.

I just grind them myself from standard twist drills. Takes
a couple of minutes. The point is not as dramatic and
the gullets shallower on the ones I make, but the
holes are clean.

Rum,

Thank you for your suggestion. I checked Lee Valley and they want $138 for a set of 4 bits (“Set of 4 (5/8” to 1”) BP Drills 07J01.04 $138.00”), IMHO that is more than a smidge over Grizzly’s $20 for a set of 8 ranging from 5/8 to 1”.

I cut the dog holes in my 3” thick bench with a spade bit. It worked fine.

Jesse, I’ve have a set of brad points from an import (not Grizzly’s) but found them to completely useless. The runout was TERRIBLE. I tried to tune them with a micro set of files and the got slightly better but still totally sucked. I was lucky to find the complete 28 piece set from lee-valley on ebay with only 4 bits missing the protected wax for 85.00 shipped, they are super-good bits. IMHO, I would never purchase a cheap import set again. I have seen some middle of the road price bit, but I’m not sure where. Hope this helps.

I use brad point bits a lot for smaller holes but prefer Forstner bits for larger holes and when I need really clean entry holes. I just bought a new set of 14 Porter Cable Forstner bits from Lowes for $49 (1/4-2 1/8”) that I am pleased with.

I suspect Rum was talking about the single Lee Valley 3/4” bit was slightly more than the Rockler and Woodcraft bits. About $30 v.s. $18 – $20.

But the Lee Valley bits are great bits and they are HSS which will stay sharp 10X longer than the carbon steel bits from Rockler or Woodcraft. They also have different shaped entry lips which slice the fibers as the bit enters the surface and make very clean holes.

I don’t think anyone really picked up on the point that the OP was comparing single bits from Rockler and Woodcraft to a set of six bits from Grizzly for about the same price. At least, no one mentioned this in their responses.

I agree that Forstner bits are the way to go for large holes, but I really like brad points for deep holes where I need to be sure the hole is absolutely straight. A Forstner can wander; and so will a spade bit.

I have a set of COLT twin land, brad point bits (from Woodcraft) and that is what I drilled my dog holes with. They work well, but I wish I had known about the Lee Valley bits before I got these. I think Woodcraft has discontinued these so maybe it’s a moot point anyway.

Yes I was compareing a single bit for about 20 to a set of bits for the same price. I was thinking if Grizzly bits are good quality I could get more bit for my money. I love my Grizzly band saw so I wondered about the quality of Grizzly bits.

I like brad point bits for deep holes as I think the sides of the bit in the existing hole tends to keep the bit from wondering.

Yes I was comparing the Lee Valley single bit to the Rockler/Woodcraft single bits, for the price difference between those three I’d go with the well known quality option.

I can’t say anything about the grizzly bits because I’ve never used them myself. If you want a single high quality bit that will cut cleanly and last a long time (barring nails :D) the lee valley is a “good deal” dollars for pain free holes drilled. I do agree its not really comparable with the price on the grizzly set, so I think its a question of how much you care about the guaranteed quality.

I would also say that I’ve come around from trying to get sets of tools more and have gone more towards paying a little more for the one tool I really need. If you don’t need the other three sizes they don’t really “add value” so you are still (effectively) paying $20 for one bit if that is the only one you use. This has enabled me to have fewer tools (and less clutter.. well.. the clutter issue is a work in progress e_e) of higher quality which means they often work better, I get better results and in the end.. I think I’m actually spending less money.

Not discouraging you from going ahead and trying the grizzly set, it may well work perfectly but I can see the grinding marks in the zoom in picture of the larger bit at the end of it. So personally I wouldn’t expect an exceptionally clean hole. If you are seriously budget constrained it might be worth the chance as worst case you’ll have some long drill bits you can use in the cases where the length is useful but the cut quality isn’t (assuming the worst which may well not be true).

The number of holes you are talking about drilling is de minimis so I’d expect any of these bits to last you many many years.

Have your say...
