Topic tags/keywords: table saw worm drive skil bosch

Skilsaw just announced a new portable table saw. So what, right?

What’s interesting is the words on the left side of the table. Instead of being direct drive, as every other jobsite saw out there, this one will integrate a worm drive. How much will this change the potential for using a jobsite saw in the workshop?

One of the biggest problems/complaints of jobsite saws is that they generate their rated horsepower through speed, with the universal motor spinning the blade at 5000 rpm or more. Works fine for the construction site, but has very little torque for plowing through hardwood and the high blade speed frequently causes burning. Worm drive should totally change that, slowing the blade speed and generating tremendous torque.

The frame of the saw is obviously based on the Bosch GTS1031 (Skil is one of Bosch’s brands) and it appears the fence will be the same, too.

The GTS1031 has gotten consistently good reviews, so I would expect this new model to follow. Another small note in the press release is that the new saw will include a Diablo blade. Good to see a manufacturer including a quality blade from the factory instead of the crappy ones that are usually installed. Of course, Bosch also owns Freud/Diablo, so they are keeping it in house, but the principle still holds.

I’m thinking that this could be a game changer for those with small shops—an easily stored saw with the power to plow through tough hardwoods. Of course there are other downsides to jobsite saws, but it seems to me that this could be a legitimate option for the woodworker.

What do you think?

Looks interesting. I can see some guys using it to build a workcenter around, in order to save some space. Any word on whether or not you can use a dado stack with it?

The Bosch can use up to a 1/2in wide dado stack, so it’s very possible this one will be similar. Have to wait until more details come out to know for sure, though.

Looks cool. I always thought skilsaw was a craftsman thing, never would have guessed it is Bosch.

I love Bosch tools. Their routers are incredible, even realized their router bits are made in USA.

As a guy with a small footprint shop I really like this as an option. Poor power and/or poor fences have kept me from pulling the trigger on a traditional jobsite saw so this could reopen that door for me.

If they were to add the worm drive to their REAXX saw, once the litigation is settled, I think that could be a real game changer in the portable saw market.

Few if any job site table saws are direct drive, they are gear driven using parallel axis helical or straight cut gears to reduce the speed of the universal motor, while increasing torque and lowering the motor to allow maximum depth of cut. Worm drive gear trains are less efficient, however, in many applications more robust given the same space constraints. Skil/Bosch has had a very tenured history of producing worm drive saws allowing spindle speed lower than that of traditional spur/pinion arrangements without reducing the depth of cut. Horsepower is always calculated the same, no manufacturer has a proprietary formula for determining this. Many do deviate from how this is measured and advertise false claims based on initial in rush current or rapid braking. No one will ever achieve more than 2.41 horsepower from 15A @ 120V as doing so would violate the laws of physics. SAE standards do exist and more manufacturers are using standardized tests to determine more realistic horsepower figures vs. the inflated claims generated for marketing purposes.
