Triumph Twist Drill 012637 Wire Size 37 Drill Bit

Product Description

The TRIUMPH TWIST DRILL 012637 is a jobber-length drill bit designed for precision drilling in metal, alloy steel, carbon steel, and wood. Built from M7 high speed steel with an oxide and gold coating, it delivers extended wear resistance in high-production environments. The 135-degree split point reduces walking and allows self-centering starts without a center punch. At 2.5 inches overall length with a 1.4375-inch flute, this bit fits standard drill chucks and is sized at wire gauge 37, equivalent to 0.1040 inches. Licensed tradespeople and machinists reach for this bit when accuracy and tool life matter in repetitive drilling operations.

This drill bit is suited for use in residential, commercial, and light industrial settings where wire-gauge-sized holes are required. Common applications include drilling alloy steel, carbon steel, and wood substrates. The T2HD series is a heavy-duty line engineered for high-performance output in production drilling scenarios. The straight-cylindrical shank seats cleanly in keyless or keyed drill chucks on handheld drills and drill presses alike. The regular spiral flute type promotes chip evacuation during cutting.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and tool-and-die professionals. Secure the shank fully in the drill chuck before operation and verify chuck tightness. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and improve hole quality. Inspect the cutting edges and web before each use and replace the bit if chipping or excessive wear is present.
