Precision Twist Drill 5997020 No. 33 Hss Jobber Drill

Product Description

The PRECISION TWIST DRILL 5997020 is a high speed steel jobber-length drill bit sized to wire gauge No. 33, with a decimal diameter of 0.1130 inches. It features a 135-degree split-point tip for fast engagement and reduced walking on contact, making it well-suited for production drilling and maintenance work on steel, aluminum, and non-ferrous materials. The bright, uncoated finish keeps heat dissipation straightforward without added coating cost. Overall length is 2.625 inches with a 1.5-inch flute length and a straight cylindrical shank. Two regular spiral flutes evacuate chips efficiently through the cut. Web-thinning at the tip lowers thrust requirements and improves hole entry on harder stock.

This bit is intended for general-purpose drilling applications in metal fabrication, maintenance and repair, and light manufacturing environments. Primary workpiece materials include steel, aluminum, and other non-ferrous metals, corresponding to ISO material codes P, M, K, N, and S. The QC21P series is built to ANSI standards and fits the typical workflow of machinists, tool-and-die techs, maintenance electricians, and plumbers who need reliable small-diameter bits for pilot holes, tap preparation, or close-tolerance work.

Key Features

Compatibility

Designed as a general-purpose jobber drill bit for use in standard keyless or keyed drill chucks accepting a 0.1130-inch straight shank, compatible with bench drills, drill presses, and hand drills used across HVAC, plumbing, electrical, and light fabrication trades.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and trade professionals working with portable or stationary drilling equipment. Secure the straight shank firmly in the chuck before operation and verify chuck key removal before powering the tool. When drilling steel, use a cutting fluid or lubricant to extend tool life and maintain hole quality. Do not exceed the recommended maximum drilling depth of 1.5 inches for this bit length.
