This depth stop system is designed for forstner bits and drill bits up to 60mm in diameter. 

Choose from one of the 6 supplied bushing that fits your drill/forstner bit (5/6/7/8/9/10), slide the bushing in the enclosure's integral bearing, slide over the shank to desired depth and lock in place with set screw. Slide the second (same size) bushing over the top of the stop and bushing and secure in place with the set screw on the second bushing.

The depth stop has a built in bearing, which keeps the stop motionless while forstner bit spins, which allows the stop to rest on the stock without marking or burning the wood. Forstner bit not included.

Note: Bushes are locked with a grub screw. Includes allen key.
