Precision Twist Drill 6000769 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000769 is a taper length drill bit engineered for general-purpose hole-making across a wide range of metallic and non-metallic materials. Built from high speed steel with a bright uncoated finish, it features a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip clearance at the point. The straight shank measures 0.5512 inches in diameter, matching the drill diameter for use in standard chucks. With an overall length of 8.4375 inches and a 5.5-inch spiral flute, this bit provides the extended reach required for deeper hole applications where jobber-length bits fall short.

This Series 5ATL taper length drill bit is suited for machinists, fabricators, and maintenance professionals working in production and repair environments. The right-hand spiral flute and web-thinned point make it effective in drill presses, CNC machines, and manual milling setups. It performs across a broad material range including carbon steel, alloy steel, stainless steel, cast iron, aluminum, brass, bronze, copper, nickel alloys, magnesium alloys, malleable iron, hardened steel, high strength bronze, cermet, graphite, and reinforced plastics. The 6xD flute-to-diameter ratio supports chip evacuation during moderate-depth drilling operations.

Key Features

• High speed steel construction for durability across general-purpose metalworking applications

• Taper length body at 8.4375 inches overall for extended reach beyond standard jobber bits
• Spiral flute length of 5.5 inches with 6xD flute-to-diameter ratio for effective chip removal
• Bright uncoated finish suitable for use with cutting fluids across a wide material range
• Conforms to DIN 340 specification for dimensional consistency

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks and collet systems accepting a 0.5512-inch straight shank. Rated for use in alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, cermet, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel.

Installation Notes

This bit is installed and serviced by machinists, tool and die technicians, and maintenance mechanics. Before mounting, ensure the drill press, lathe, or CNC spindle is fully powered down and locked out per applicable safety procedures. Secure the straight shank firmly in a properly sized chuck or collet to prevent runout. Coolant-through is not supported on this bit; apply cutting fluid externally as required for the workpiece material.
