Bosch: Getting Around to a New Rotary

Bosch: Getting Around to a New Rotary

Rotary saws aren’t just for drywall anymore, which is one reason Bosch has revamped their offering into the new 1639 rotary saw. It replaces their previous saw, the 1638, by putting 43 percent more power into your hands than its predecessor.
The 1639’s 5-amp motor (compared to a 3.5 amp on the older model) can cut through particle board and composites, as well as plaster, ceramic wall tile and cement board. When you’re making those cuts, you can also switch between a speed of 25,000 rpm for thicker materials and a speed of 30,000 rpm for the rest of your work. The bump-off switch allows for one-handed operation.

When you get to the bottom of the tool, you’ll see the additional upgrades Bosch has added to the 1639: a high-impact, glass-filled nylon foot plate and depth guide. This material won’t bend or break as easily as metal, and it won’t scratch your work surface, either. The depth guide/base also now has quick-clamp assembly: it’ll attach, adjust and detach in seconds.

The 1639 comes with collets to accept all 1/8″ and 1/4″ rotary saw bits, including those from Bosch competitors. It’s also available in a kit with carrying case, additional bits and a circle cutting guide. Optional accessories include a dust extraction hood and vacuum adapter. The 1639 by itself sells for $130.
