Precision Twist Drill 6000103 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000103 is an extra length, high-speed steel twist drill bit designed for through-hole and deep-hole drilling applications where standard length bits cannot reach. Built to ANSI standards, it features a 0.4062-inch diameter, a 118-degree standard point angle, and a bright uncoated finish. The 8-inch overall length and 6-inch spiral flute length give technicians, machinists, and tradespeople the reach needed for deep-stack or obstructed workpiece conditions. The web-thinned, tapered web design reduces thrust and improves chip evacuation during drilling. This bit is sold individually and suits both production and maintenance drilling environments.

This drill bit is suited for use on aluminum, magnesium, copper, nickel, titanium, and synthetic materials as its primary workpiece targets. Secondary workpiece materials include stainless steel, hardened steel, nickel alloys, magnesium alloys, malleable iron, high-strength bronze, and reinforced plastics. The straight-cylindrical shank fits standard drill chucks without adapters, making it a practical choice for machine shop setups, HVAC equipment fabrication, mechanical contractors, and maintenance technicians working with varied metal assemblies.

Key Features

• Extra length design: 8 inches overall length with 6 inches of spiral flute for deep-hole reach
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High-speed steel construction, bright uncoated finish — no coating buildup on cutting edge
• Right-hand, regular spiral, 2-flute configuration promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without specialized tooling
• ANSI-certified general-purpose grade; Series 860

Compatibility

Compatible with aluminum, magnesium, copper, nickel, titanium, synthetic materials, stainless steel, hardened steel, nickel alloys, magnesium alloys, malleable iron, high-strength bronze, and reinforced plastics. Fits any drill chuck accepting a 0.4063-inch straight-cylindrical shank.

Installation Notes

This bit is installed by machinists, mechanical contractors, and maintenance technicians using standard drill press or hand-held drilling equipment. Secure the straight-cylindrical shank firmly in the chuck before use and verify chuck key is removed before powering the drill. When drilling deep holes, retract the bit periodically to clear chips and prevent heat buildup. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.
