Use them to create flat bottomed holes that act as seats for the heads of lag screws, washer head screws, and tee nuts. Lock the drill bit in place with the included set screw. For tough resistance to wear, corrosion, and heat, the drill bit is titanium nitride TiN coated.

Use the optional rotating depth stops to drill holes to a precise depth. The end of the collar has a ring that rotates separately from the body. When the ring touches your workpiece, it stops moving to prevent scratches or rub marks. The wide opening leaves room for chips to clear the drilling area. Lock the counterbore into position on the drill bit with the two set screws. Optional collar not included controls the cutting depth of your counterbore.
