Precision Twist Drill 6000316 Taper Length Drill Bit Q

Product Description

The PRECISION TWIST DRILL 6000316 is a taper length, straight-shank drill bit sized at 0.3320 inches in diameter, corresponding to Letter Q. 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 for improved chisel-edge performance and easier penetration. The spiral flute runs 4.125 inches, giving this bit a flute-to-diameter ratio of 6xD, and the overall length is 6.5 inches. Right-hand cut geometry and a straight shank make it compatible with standard drill chucks. This is a general-purpose bit suited for machinists, maintenance technicians, and trade professionals who need reliable performance across a wide range of materials.

The 6000316 is rated for use across an extensive range of materials, including alloy steel, carbon steel, stainless steel, cast iron, malleable iron, hardened steel, brass, bronze, high strength bronze, copper, aluminum, aluminum alloy, magnesium, magnesium alloy, nickel, nickel alloy, cermet, graphite, and reinforced plastics. This breadth of material compatibility makes it well suited for general shop use, fabrication environments, HVAC equipment drilling, plumbing rough-in work, and electrical panel installations where metal-boring is required on mixed material assemblies.

Key Features

• Letter Q size at 0.3320 inches diameter for precise, standard-referenced sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• High speed steel construction for durability across ferrous and non-ferrous metals
• Taper length body with 4.125-inch flute provides greater reach than jobber-length bits
• Bright, uncoated finish allows visual wear inspection during service life
• Regular spiral, right-hand cut with straight shank fits standard drill chucks without adapters
• Meets ANSI standards for dimensional accuracy and geometry

Compatibility

Designed as a general-purpose OEM-style taper length drill bit fitting standard three-jaw drill chucks and compatible with any drilling application calling for a Letter Q or 0.3320-inch diameter straight-shank bit per ANSI specifications.

Installation Notes

This bit is installed by machinists, maintenance technicians, and trade professionals using standard drill presses, hand drills, or CNC spindles with a compatible chuck. Always power down or de-energize equipment before changing tooling. Secure the workpiece firmly before drilling, and use cutting fluid when boring stainless steel, hardened steel, or nickel alloys to extend bit life and reduce heat buildup. Do not force the bit beyond its rated capacity or use it in impact drivers.
