Precision Twist Drill 6000252 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000252 is a high-speed steel extra length drill bit designed for deep-hole drilling in a wide range of materials. It features a 0.4844-inch diameter with a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at entry. The two-flute spiral design with a right-hand cutting direction provides consistent, controlled material removal. At 12 inches overall length with a 9-inch flute length, this bit reaches depths that standard-length drill bits cannot. It is used by machinists, maintenance technicians, and fabricators who require extended reach in production and repair drilling operations.

This extra length drill bit is well suited for drilling through thick stock, deep cross-holes, and hard-to-reach features in both production shop and field maintenance settings. The bright uncoated high-speed steel construction makes it appropriate for use in aluminum, magnesium, copper, nickel, synthetic materials, and titanium as primary workpiece materials. Secondary materials include stainless steel, hardened steel, nickel alloy, malleable iron, high-strength bronze, magnesium alloy, reinforced plastics, and steel. The straight-cylindrical shank seats in standard drill chucks without adapters.

Compatibility

Designed as a general purpose extra length drill bit compatible with standard drill chucks accepting a 0.4844-inch straight-cylindrical shank. Suitable for use in aluminum, magnesium, copper, nickel, synthetic materials, titanium, stainless steel, hardened steel, nickel alloy, malleable iron, high-strength bronze, magnesium alloy, reinforced plastics, and steel workpieces as specified by the manufacturer.

Installation Notes

Install in a drill press, milling machine, or hand drill with a chuck rated for the 0.4844-inch shank diameter. Ensure the shank is fully seated and the chuck is tightened securely before operation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting that this bit does not support coolant-through delivery. Power down and de-energize all equipment before changing or inspecting the bit.
