Precision Twist Drill 6000044 Cobalt Drill Bit Size 52

Product Description

The PRECISION TWIST DRILL 6000044 is a cobalt high-speed steel jobber length drill bit in wire gauge size 52, measuring 0.0635 inches in diameter. It features a 135-degree split point with web thinning for improved centering and reduced feed force on hard materials. The straight-cylindrical shank and regular spiral flute geometry deliver consistent chip evacuation during drilling operations. Overall length is 1.875 inches with a 7/16-inch flute length. This bit is designed for use by machinists, maintenance technicians, and metalworking tradespeople who need reliable performance in ferrous and non-ferrous materials.

This drill bit is suited for precision drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its cobalt content and oxide bronze finish provide heat resistance and surface protection, making it appropriate for production drilling and repair work where tool life matters. The NAS 907 specification ensures dimensional and performance consistency. It is commonly used in industrial maintenance, sheet metal work, and fabrication shops where small-diameter accuracy is critical.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or metalworking technician. Secure the workpiece and verify spindle alignment before drilling to prevent bit deflection at this small diameter. Use appropriate cutting fluid for the workpiece material to extend tool life. Do not exceed recommended feed and speed parameters for the bit diameter and material combination.
