Precision Twist Drill 6000248 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000248 is a taper length drill bit designed for general-purpose drilling across a wide range of materials. Built from high speed steel with a bright/uncoated finish, this bit features a 118-degree standard point angle and a right-hand spiral flute for efficient chip evacuation. At 0.0330 inches in diameter (wire size #66) and 2 inches overall length, it is engineered for precision work in tight-tolerance applications. A web-thinned, tapered web configuration reduces thrust and improves point accuracy. This bit belongs to Precision Twist Drill Series R52 and is installed by machinists, maintenance technicians, and trade professionals working with hand or bench drill equipment.

This drill bit is suited for use on a broad spectrum of materials including alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, aluminum, aluminum alloy, magnesium, magnesium alloy, brass, bronze, high strength bronze, copper, nickel, nickel alloy, cermet, graphite, and reinforced plastic materials. Its 0.75-inch flute length at a 6xD flute-to-diameter ratio makes it appropriate for applications requiring a longer reach than a jobber-length bit while maintaining rigidity. General-purpose performance classification makes it a practical choice for production and repair drilling in shop and field environments.

Key Features

• High speed steel construction for durability across ferrous and non-ferrous materials
• 118-degree standard point angle for general-purpose drilling accuracy
• Web-thinned tapered web reduces drilling thrust and improves centering
• Right-hand spiral flute promotes efficient chip removal during drilling
• Straight shank with 0.0330-inch shank diameter for standard chuck compatibility
• Meets ANSI standards for dimensional consistency

Compatibility

Designed as an OEM-style general-purpose taper length drill bit compatible with standard straight-shank drill chucks accepting bits at 0.0330-inch shank diameter.

Installation Notes

This drill bit is installed by machinists and trade technicians using hand drills, drill presses, or CNC equipment with appropriate chuck capacity. Secure the straight shank firmly in the chuck before operation and verify chuck runout is within acceptable tolerance to protect the small-diameter bit from deflection. At 0.0330 inches in diameter, this bit is susceptible to breakage under side load or excessive feed pressure — use appropriate feed rates for the material being drilled. Always wear appropriate eye protection when drilling.
