Bosch recently launched a new 12V Max cordless die grinder on Amazon, model GWG12V-20S, their first new compact cordless power tool in quite some time.

The new Bosch cordless die grinder features a variable speed trigger, “innovative user interface and speed buttons,” and a compact design.

It features a brushless motor and spindle lock for quick accessory changes.

Bosch says that the tool’s constant electronics provide for uniform performance even at the highest speed levels.

  • 1/4″ collet
  • “Deadman” paddle switch
  • 5 speed settings
  • 4.5″ width x 7.5″ length x 2″ height
  • Weighs 1.2 lbs (tool-only)

The USA version of the kit comes with (2) compact 3Ah batteries, a compact charger, and soft tool case.

Price: $229 for the kit (GWG12V-20SB23), $169 for the tool-only (GWG12V-20SN)
ETA: February 2024


Images from overseas product listings show plus and minus buttons on the back of the tool for speed changes. I wouldn’t hail this as innovative, but the controls look straightforward and user-friendly.

Bosch has not disclosed the tool’s RPM specs, but 5 settings plus a variable speed trigger should give users fine control over the tool’s performance and material removal rate.

This is Bosch USA’s first 12V Max cordless power tool launch in what I would consider a long time, and from the looks of it, it’s only following the international release by a couple of months.

In recent years, Bosch USA launched a 12V Max cordless angle grinder, following its overseas release by more than 6 years.

The grinder looks well designed with no glaring “gotchas.”

It’s puzzling why Amazon is breaking the news about the new cordless die grinder, but this is definitely a welcome expansion to Bosch’s 12V Max cordless power tool line.

Top Competition

Milwaukee M12 Fuel Right Angle Cordless Die Grinder 2485

I would say the Milwaukee M12 Fuel right angle die grinder is Bosch’s biggest competitor, featuring 4 electronic speed control settings and pneumatic-style variable speed lever-style throttle switch.
