Precision Twist Drill 6000179 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000179 is a taper length high speed steel drill bit designed for precise, clean-hole drilling across a wide range of metal and non-metal substrates. It carries a wire gauge size of 48, corresponding to a decimal diameter of 0.0760 inches. The 118-degree standard point angle suits general-purpose drilling in both production and maintenance environments. The bright, uncoated finish allows visual inspection of the cutting edge. With a 2-inch flute length and 3-3/4-inch overall length, this bit provides the extended reach characteristic of taper length geometry without sacrificing rigidity. Machinists, tool-and-die technicians, and maintenance mechanics are the primary users.

This bit is suited for drilling operations in alloy steel, carbon steel, stainless steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, magnesium, magnesium alloy, nickel, nickel alloy, cermet, graphite, and reinforced plastic materials. The taper length format is commonly chosen when standard jobber length bits lack the reach needed for deeper features or when working inside fixtures and jigs. Right-hand spiral flutes clear chips efficiently in through-hole and blind-hole applications at moderate feed and speed rates.

Key Features

• Wire size 48 with 0.0760-inch decimal diameter for precision small-hole work
• 118-degree standard point angle for general-purpose metal drilling
• High speed steel construction provides heat resistance during sustained drilling cycles
• Bright, uncoated finish allows easy edge inspection and suits use with cutting fluids
• Web-thinned, tapered web configuration reduces thrust and improves chip evacuation
• Straight shank compatible with standard drill chucks and collet systems
• Meets ANSI standards for taper length drill geometry

Compatibility

Designed as a general-purpose taper length drill bit suitable for use in standard drill presses, CNC machining centers, and hand-held drill motors equipped with chucks or collets sized for a 0.0760-inch straight shank.

Installation Notes

Installation is performed by machinists or maintenance technicians. Secure the shank fully in the chuck or collet before applying power, and verify runout before beginning a drilling cycle. Select appropriate cutting speed and feed rate for the workpiece material to avoid overheating the cutting edge. Use a cutting fluid or coolant where the material application and machine setup allow, particularly when drilling stainless steel or nickel alloys.
