High quality metal countersinks are a necessity during the application process of steel edging or angle iron. These countersink bits have four flutes that stay sharp for a long time. Two hex bolts securely tighten the lead drill bit to the countersink about 1/2" above the flutes. These countersinks fit the 2" GRK screws.

The GRK screws and countersinks worked perfectly. Zero screws broke, zero wood split and a nice tight bite throughout.


First, I wanted to let you know that it has been a real pleasure dealing with your company. Communication has been great and the assistance with tracking our shipments has been wonderful. Second, the countersinks you sent us are worth their weight in gold! The hardware, screws, countersinks etc. were great. We were able to obtain a much closer fit from our panels to our ramps than with the traditional screws. These countersinks have cut our labor down dramatically and we experienced no chipping while drilling. The accuracy we experienced was phenomenal. Thank you again and I look forward to doing business again in the future. Jose Pineiro - Assistant Superintendent of Parks & Facilities - Round Lake Area Park District
