Walter-titex 5059397 Jobber Drill Bit No. 53 Hss

Product Description

The WALTER-TITEX 5059397 is a jobber-length, high-speed steel drill bit sized to wire gauge No. 53 (0.0595 inches decimal equivalent). Built to Series A1222 standards, it features a parabolic flute geometry with web thinning for reduced thrust and improved chip evacuation. The 130-degree drill point angle suits a broad range of workpiece materials. A bright, uncoated finish keeps the surface in its as-ground state, making wear easy to monitor during service. This bit carries ANSI and ISO compliance and is graded for high-performance drilling applications. Licensed HVAC technicians, machinists, and general trade professionals working with close-tolerance hole sizes in the No. 53 range will find this bit sized for precision pilot and clearance hole work.

This drill bit is suited for use in blind hole and stack drilling applications. Compatible primary workpiece materials include cast iron, non-ferrous metals, and steel, corresponding to material codes K, N, and P. The straight-cylindrical shank fits standard drill chucks without adapters. The overall length of 1-11/16 inches and flute length of 25/32 inches make it appropriate for benchtop drill presses, hand drills, and CNC drilling centers handling shallow to moderate drilling depths.

Installation Notes

Installation should be performed by a qualified machinist or trade professional familiar with drill press or CNC drilling operations. Secure the workpiece and confirm the drill chuck is fully tightened before spindle engagement. Observe appropriate speeds and feeds for the workpiece material category to avoid premature edge wear. Disconnect or de-energize the machine fully before changing or inspecting the bit.
