Veritas Drill Stop Gauge

Its V-shaped cross section centers and aligns the drill bit, so you're not juggling a rule, the bit and a hex key all in one hand while tightening a drill stop or countersink in place.

The 110° angle accommodates bits up to 1" in diameter, covering the sizes typically used for depth-stop or countersink setting.

Yes, it's graduated in both scales, in sixteenths of an inch and in millimetres, so it works whichever measurement system your project uses.

It's aluminum with an anodized finish, and the markings are laser-etched for clear reading of the scale.
