SHOCKWAVE™ Impact Duty 11/16"x12" Lineman's Fiberglass Drill Bit

Drill clean, precise, single-pass holes through composite utility poles and crossarms with the Milwaukee® SHOCKWAVE™ 11/16" x 12" Lineman's Fiberglass Drill Bit. Engineered specifically for power linemen and line maintenance crews, this heavy-duty bit features premium carbide-tipped cutting edges that cut cleanly through tough fiberglass without delamination or binding. Its 12-inch overall length allows crews to bore completely through utility crossarms in one single pass—eliminating unnecessary pole rotation and misaligned entry/exit holes. Built with an optimized flute geometry that evacuates dense resin dust quickly and a 7/16-inch quick-connect hex shank, it is fully optimized to harness the power of the Milwaukee M18 FUEL™ 7/16" Hex Utility High Torque Impact Wrench (2865-20).

Key Features:

• True Single-Pass Drilling (12" Length): 12-inch extended flute cleanly passes through standard utility crossarms without flipping or realigning from the opposite side.

• Precision 11/16" Diameter: Engineered to produce clean, straight holes sized accurately for standard utility hardware and through-bolts.

• Carbide-Tipped Cutting Edges: Hardened carbide tip reduces cutting friction, resists severe abrasion, and dramatically prolongs cutting edge life.

• Optimized Flute Geometry: Flute path rapidly channels composite shavings and fiberglass dust away from the tip to eliminate clogging.

• 7/16" Quick-Connect Hex Shank: Industrial heat-treated shank withstands extreme impact torque while ensuring secure retention in compatible utility drivers.

• Impact-Duty Optimization: Designed specifically to pair with high-torque utility tools such as the Milwaukee 2865-20 impact wrench.

• Laser-Etched Size Markings: High-contrast laser etching ensures fast, permanent size and part identification in lineman buckets.

• Material Compatibility: Built for fiberglass and composite utility poles; not recommended for drilling concrete.
