Precision Twist Drill 6000128 Taper Length Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 6000128 is a taper length drill bit designed for general-purpose drilling across a wide range of materials. It measures 0.1065 inches in diameter (Wire Size #36) and features a 118-degree standard point angle with web thinning for easier penetration and reduced thrust. The bit is made from high speed steel (HSS) with a bright/uncoated finish and a straight shank. At 4.625 inches in overall length with a 2.5-inch spiral flute, it provides extended reach compared to jobber-length bits. This is a Series R52 tool intended for use by machinists, maintenance technicians, and trade professionals who need reliable general-purpose drilling performance.

This taper length drill bit is suited for drilling operations in metal fabrication, maintenance, repair, and light manufacturing environments. Its extended flute length relative to diameter (6xD ratio) makes it well suited for deeper hole applications where a standard jobber bit falls short. The right-hand spiral flute and tapered web configuration support chip evacuation across a broad range of workpiece materials. It is a single-piece, individually packaged item.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drilling operations.

Appropriate cutting fluid or lubricant is recommended when drilling ferrous metals to extend tool life. Follow applicable shop safety standards and wear appropriate PPE including eye protection during all drilling operations.
