Star M Rotating Drill Depth Stopper for Drill and Auger Bits from 3mm to 30mm
Drill Stopper made by Star M, a manufacturer of high-quality boring bits based in Miki, Japan.
These drill bit depth stops allow complete and precise depth control when drilling with hand drills or braces. Stops can be attached to any twist, brad point or auger bit from 3mm to 30mm via a supplied Allen screw. When set, these stops prevent further drilling once the desired depth is reached. As soon as the depth stop touches the work surface, it stops spinning to let you know you have reached your desired depth. As the large resin body contacts the work surface, it will not cause damage. The window in the side gives the operator an excellent view of the drilling process and provides clearance for chips. Bits can be fitted with a drill stop with up to 0.5mm difference in size. For example, a 5.5mm drill can be used with a 6mm drill stop. Available in 19 sizes. Each stop supplied with an Allen wrench.
