The STAR-M bit depth stops have integral ball bearings, so that when the coloured stop contacts your work surface, it immediately stops rotating. Typical depth stops continue to turn with the bit and leave a mark on the work surface

The drill stopper can be adjusted simply by using supplied allen key to release locking screw and setting to correct height and re-tightening locking screw.

Suitable for use with Auger Bits, Steel Drill Bits & Masonry Bits.

Suits drill bits 5mm in diameter. 

Dimensions: 25mm high x 22mm in diameter
