Triumph Twist Drill 012636 Jobber Drill Bit Wire 36 Hss

Product Description

The TRIUMPH TWIST DRILL 012636 is a jobber-length drill bit in wire gauge size 36 (0.1065 inches decimal), built from M7 high speed steel with an oxide/gold coating for added lubricity and surface protection. The 135-degree split point provides self-centering entry and reduces walking on hard materials, making it well suited for production drilling in alloy steel, carbon steel, and wood. At 2.5 inches overall length with a 1.4375-inch spiral flute, it delivers a compact yet capable reach for standard jobber applications. The straight-cylindrical shank seats securely in standard drill chucks without slippage.

This bit is designed for right-hand cutting in a variety of workpiece materials including alloy steel, carbon steel, and wood. Its web-thinned, tapered web configuration reduces thrust requirements and improves chip evacuation in tighter cuts. The T2HD series targets high-performance, heavy-duty drilling scenarios where a standard black-oxide bit would wear prematurely. Typical install environments include machine shop production lines, fabrication benches, and field service work requiring consistent, repeatable hole quality in ferrous and non-ferrous materials.

Key Features

• Wire gauge size 36, 0.1065 inches decimal diameter for precise small-diameter hole applications
• 135-degree split point with web thinning for self-centering entry and reduced thrust
• M7 high speed steel construction rated for heavy-duty, high-performance drilling
• Oxide/gold coating improves lubricity and extends tool life in ferrous materials
• Regular spiral flute with tapered web promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement or direct-use jobber-length drill bit for standard 3-jaw and keyless drill chucks accepting straight-cylindrical shanks at 0.1065 inches diameter. Compatible primary workpiece materials per manufacturer specifications include alloy steel, carbon steel, and wood.

Installation Notes

This bit is installed by machinists, fabricators, and trade professionals using bench-top or handheld drilling equipment. Secure the shank fully in the chuck before operation and confirm concentricity to avoid premature tip breakage at this small diameter. Use appropriate cutting fluid for ferrous metals to extend tool life. Inspect the split point for chipping before each use, as small-diameter bits are susceptible to tip damage if dropped or improperly stored.
