Walter-titex 5153963 Jobber Drill Bit 37/64 in Hss

Product Description

The WALTER-TITEX 5153963 is a jobber length drill bit designed for high-performance drilling in ferrous and non-ferrous materials. It measures 37/64 inches (0.5781 inches decimal) in diameter with a 130-degree drill point angle and a parabolic flute geometry that improves chip evacuation and reduces heat buildup at the cutting edge. The overall length is 6-5/8 inches, and the bit is manufactured from high speed steel with an oxide coating to extend surface life under production drilling conditions. It is installed and used by machinists, maintenance technicians, and metal fabricators working with manual or CNC drilling equipment.

This drill bit is suited for use on cast iron, non-ferrous metals, and steel in both blind hole and stack drilling applications. The parabolic flute design with a flute-to-diameter ratio of 8xD supports deeper drilling passes with fewer pecking cycles. The web-thinned, tapered web configuration reduces thrust requirements at entry, making it a practical choice for production environments where cycle time and hole quality both matter. It is appropriate for residential and commercial maintenance shops as well as light industrial settings.

Key Features

• 37/64 inch diameter (0.5781 inches decimal) with h8 diameter tolerance for consistent fit
• 130-degree standard point angle with web thinning for reduced entry thrust
• Parabolic flute geometry at 8xD ratio promotes efficient chip removal in deep holes
• Oxide-coated high speed steel construction for enhanced wear resistance
• Straight-cylindrical shank (37/64 inches diameter, 2.166 inches shank length) fits standard drill chucks
• Rated for blind hole and stack drilling applications across cast iron, steel, and non-ferrous metals
• Meets ANSI and ISO standards; specification designation includes BS and DIN

Compatibility

The WALTER-TITEX 5153963 belongs to Series A1222 and is designed for use in standard drill chucks accepting a straight-cylindrical shank. Primary workpiece material compatibility includes cast iron, non-ferrous metals, and steel as specified by the manufacturer.

Installation Notes

This drill bit is installed by machinists or maintenance technicians using a standard drill press, mill, or handheld drilling tool. Ensure the drill chuck is securely tightened and the workpiece is properly clamped before beginning operations. Coolant-through is not supported on this bit; external cutting fluid or appropriate dry-cutting practice should be applied based on material type. Inspect the cutting edges and point for wear or chipping before each use and replace when performance degrades to maintain hole quality and dimensional accuracy.
