Precision Twist Drill 6000797 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000797 is a taper length, straight-shank drill bit designed for general-purpose drilling across a wide range of materials. Built from high speed steel with a bright/uncoated finish, it measures 0.7087 inches in diameter with a 118-degree standard point angle. The spiral flute geometry and web-thinned, tapered web configuration promote efficient chip evacuation and reduce thrust during entry. Right-hand cut action is standard. This bit is suited for use in production shops, fabrication environments, and maintenance applications where a longer flute length is required to reach depth without a reduced-shank extension.

The 6000797 is rated for use in alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, magnesium, magnesium alloy, nickel, nickel alloy, cermet, graphite, and reinforced plastic materials. The 6xD flute-to-diameter ratio makes it well suited to through-hole drilling in moderate-thickness stock where a jobber-length bit falls short. Machinists, tool-and-die workers, and maintenance mechanics are the primary installers and operators.

Key Features

• 0.7087-inch diameter with matching 0.7087-inch straight shank — no step-down at the shank
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• 6.219-inch (6-7/32 inch) flute length provides extended reach compared to jobber-length bits
• 9.5-inch (9-1/2 inch) overall length for deep-hole access
• High speed steel construction for broad material compatibility including stainless and hardened steel
• Meets DIN 340 specification — Series 5ATL
• Bright/uncoated finish — no coating to chip or delaminate in interrupted cuts

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks and milling machine spindles accepting a 0.7087-inch (18.00 mm) straight shank. Conforms to DIN 340 specification under Series 5ATL.

Installation Notes

Secure the shank firmly in a properly sized drill chuck or collet before operation and verify runout is within acceptable limits for the application. Use appropriate cutting fluid or coolant for the workpiece material, particularly when drilling stainless steel or hardened steel, to extend tool life. Do not exceed the rated speed range for high speed steel tooling in the material being cut. Inspect the cutting edges and web condition before each use and redress or replace the bit if chipping or excessive wear is observed.
