Fibreglass Drill Bits

Our SHOCKWAVE Impact Duty™ Lineman’s Fiberglass Drill Bits are engineered to deliver cleaner, straight through holes in composite and fiberglass utility poles and crossarms. Our carbide tip design reduces friction, allowing you to make faster, cleaner cuts while maintaining best life. Our fiberglass drill bits are available 22″ lengths, which can pass through power utility poles and arms in a single pass. These bits maximise productivity by eliminating the need to flip over the pole, line up holes, and drill through the other side. The heated treated carbon 7/16″ hex shank increases strength and durability when drilling through fiberglass and composite power utility poles. Pair these bits with the MILWAUKEE® Hex Utility High Torque Impact Wrench for ultimate performance.
