SHOCKWAVE™ Impact Duty 13/16"x12" Lineman's Fiberglass Drill Bit

Drill faster, cleaner, straight-through holes in composite utility poles with the Milwaukee® SHOCKWAVE™ Lineman's Fiberglass Drill Bit. Specifically engineered for power utility linemen and distribution crews, this high-performance bit cuts effortlessly through abrasive fiberglass and resin crossarms without tearing or binding. Its durable carbide-tipped cutting geometry significantly lowers friction to accelerate cutting speeds while delivering maximum bit longevity. Available in extended 12" and 22" lengths, it passes completely through poles in a single pass—eliminating the hassle of flipping heavy utility poles or attempting to realign bores from the opposite side. Featuring a heat-treated 7/16" quick-connect hex shank, it is fully optimized to withstand the high torque output of the Milwaukee M18 FUEL™ 7/16" Hex Utility Impact Wrench (2865-20).

Key Features:

• True Single-Pass Capability: Available in 12" and 22" overall lengths to drill straight through composite poles and arms without flipping or realignment.

• Carbide-Tipped Cutting Edges: Wear-resistant carbide head minimizes friction, speeds up drilling rates, and extends edge life in abrasive materials.

• Optimized Flute Geometry: Flute profile aggressively ejects dense fiberglass shavings and composite dust to prevent clogging.

• Heavy-Duty 7/16" Hex Shank: Heat-treated carbon steel shank provides exceptional torsional strength and ensures secure quick-connect locking.

• Utility Impact Optimized: Built to harness the torque profile of the Milwaukee M18 FUEL™ 7/16" Hex High Torque Impact Wrench (2865-20).

• Clear Laser-Etched Markings: Permanent laser etching ensures effortless diameter and model identification in utility buckets and staging boxes.

• Pole Material Rating: Purpose-built for fiberglass and composite distribution structures (not rated for concrete poles).
