Bosch recently announced their new corded CSW41 worm drive circular saw that they say delivers unmatched comfort and control and answers user demands for a lightweight saw without compromising durability and power.
- Weighs 13.2 pounds
- 17-1/2″ length
- 7-1/4″ blade size, diamond arbor shape
- 5300 RPM
- All-magnesium construction [except for the blue and black handles]
- Max bevel capacity: 53° with positive stop at 45°
- Max cutting depth at 90°: 2-3/8″
- Max cutting depth a 45°: 1-15/16″
- 15A ball bearing motor
- Built-in hook
- On-board storage for included multi-function wrench
- Compatible with WD7RIP adjustable fence and WD7LUB gear lubricant
Bosch designed the new saw specifically for concrete form builders, framers, deckers, general contractors, and other types of users who are looking for a heavy duty saw in a lightweight package.
The saw is packaged with a 24T blade.

The new Bosch CSW41 very closely resembles the recent Skil Mag77LT worm drive saw, which also retails for $219 via Amazon.
I took a look at Bosch’s current magnesium-construction worm drive circular saw, model 1677M ($192-210 via Amazon). That model has similar cutting capacity as the new CSW41, but weighs in at 14 lbs.
In other words, the new Bosch CSW41’s is lighter than Bosch’s current model and is competitive with other brands’ worm drive saws. It seems that there is not much that can be done to decrease the weight further without compromising strength or performance.
One thing I did notice was that the new Bosch saw has a faster motor than competing models. This could potentially translate to higher application speeds.
I tend to favor Bosch corded power tools over other brands’, and so this would probably be my pick if I were looking to buy a magnesium-bodied worm drive saw in the near future.
