Triumph Twist Drill 012648 Drill Bit Wire Size 48 Hss

Product Description

The TRIUMPH TWIST DRILL 012648 is a jobber-length drill bit sized to wire gauge 48 (0.0760 inches decimal), designed for precision drilling in metal and wood applications. Built from M7 high-speed steel with a gold oxide coating, it delivers extended wear resistance in high-speed operations. The 135-degree split point and web-thinned tip promote self-centering on contact, reducing the need for a center punch and minimizing walking on hard surfaces. At 2 inches overall length with a 1-inch spiral flute, this bit is suited for close-quarter drilling where a full-length bit would be impractical. Licensed machinists, tool-and-die workers, and HVAC or plumbing technicians drilling small-diameter pilot holes rely on this type of bit for consistent, repeatable results.

The 012648 is intended for use in standard drill chucks and drill presses across a wide range of applications. Its straight-cylindrical shank seats securely in both keyed and keyless chucks without slippage. The listed primary workpiece materials include alloy steel, carbon steel, and wood, making it versatile for light fabrication, sheet metal work, and finish carpentry requiring small-diameter through-holes. The regular spiral flute geometry clears chips efficiently at normal feed rates, reducing heat buildup during extended runs.

Key Features

• Wire gauge size 48 (0.0760 inches) for small-diameter precision drilling
• M7 high-speed steel construction rated for heavy-duty, high-performance use
• Gold oxide finish improves lubricity and surface hardness for longer tool life
• 135-degree split point with web thinning for self-centering entry and reduced thrust
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and drill presses

Compatibility

Designed as a direct-fit replacement or standard jobber-length drill bit for any drill press, hand drill, or CNC spindle accepting a straight-cylindrical shank of 0.0760 inches diameter. Suitable for workpieces in alloy steel, carbon steel, and wood as specified by the manufacturer.

Installation Notes

Installation of this bit is performed by machinists, fabricators, or trade professionals familiar with rotary cutting tools. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits before drilling. Wear appropriate eye protection and ensure the workpiece is clamped or fixtured securely before contact. Do not exceed the rated feed and speed range for the workpiece material to avoid premature tip failure or bit breakage at this small diameter.
