Precision Twist Drill 6000502 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000502 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 features a 118-degree standard point angle and a right-hand spiral flute with a web-thinned, tapered web configuration. The bit measures 0.0669 inches in diameter with an overall length of approximately 2-63/64 inches and a flute length of 1-31/32 inches. It conforms to DIN 340 standards and is part of the Series 5ATL line. Machinists, tool-and-die technicians, and general fabrication shops will find this bit suited to precision small-diameter drilling applications.

This drill bit is sized at 1.70 mm (0.0669 inches) diameter and is appropriate for use in manual drill presses, CNC machining centers, and benchtop drilling operations. Its taper length geometry provides additional flute clearance compared to jobber-length bits, which helps with chip evacuation in deeper holes. The 6xD flute-to-diameter ratio makes it well suited for applications requiring drilling depth beyond standard jobber reach without moving to a full extra-long bit.

Key Features

• High speed steel construction for durability across general-purpose drilling tasks
• 118-degree standard point angle with web-thinned, tapered web for improved penetration and reduced thrust
• Bright/uncoated finish suitable for a broad range of workpiece materials
• Right-hand cut, regular spiral flute with 6xD flute-length-to-diameter ratio for effective chip clearance
• Straight shank for compatibility with standard drill chucks
• Conforms to DIN 340 specification for consistent dimensional accuracy

Compatibility

Compatible material applications include 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

Installation and use of this bit is performed by machinists or qualified fabrication technicians. Secure the straight shank fully in a properly sized drill chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Small-diameter bits are susceptible to breakage under side loading or excessive feed pressure — use consistent, controlled feed rates. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling harder materials to manage heat.
