High quality countersinks are a necessity during the application process of the dense ramp surfacing. These countersink bits have four flutes that stay sharp for a long time compared to the less expensive single flutes. Two hex bolts securely tighten the lead drill bit to the countersink about 1/2" above the flutes.
Expect to use one of these countersinks per four sheets of ramp surfacing. If your ramp takes 16 sheets of Skatelite Pro or Ramp Armor Deluxe, you'll want to order a four pack of countersinks. These countersinks fit the thicker 2" GRK screws that we sell.
