Item #

This package includes the Bosch GOP40-30 oscillating multi-tool with the Starlock PLUS 3D accessory interface. This interface boasts more surface area between the tool and accessory, and a three-dimensional bottle cap-like connection for better torque transfer. It also features incredibly easy, no-touch blade changes—just press the tool down onto the blade and it snaps into place. To eject, pull the lever—there is no need to touch a hot blade. The professional-grade 4.0-amp motor delivers a top speed of up to 20,000 oscillations per minute, and the tool has a 3.0° oscillating arc. A variable-speed dial allows the user to set the optimal speed, while Constant Response circuitry maintains the desired speed under load. At only 3.3 lbs., it is lightweight and compact enough to reach into tight spaces. Ideal for flush cuts such as door-jamb cuts (using various plunge or segment blades). Compatible with all Starlock and StarlockPlus accessories.

I own this tool and love it, but i'm in desperate need of a replacement sanding pad. Any suggestions?

Can it cut round glass bottles???
Chandra S on Jul 29, 2019
BEST ANSWER: Yes, with the appropriate blade. However, I wouldn’t recommend it. Probably better to use a traditional glass scoring tool for a round glass bottle.
Cost of replacement blades?
