Walter-titex 5337237 Screw Machine Drill Bit 13/64 in Cobalt

Product Description

The WALTER-TITEX 5337237 is a screw machine length cobalt drill bit designed for high-productivity drilling in demanding materials. Built to Series A1149XPL, it features a 130-degree split point, parabolic flute geometry, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The 13/64 inch (0.2031 inch) diameter and compact 2.4409-inch overall length make it well suited for close-tolerance, short-hole applications on the shop floor or in the field. It is installed by machinists, maintenance technicians, and fabricators working with drill presses, CNC machines, and hand-held power tools requiring a straight-cylindrical shank.

This bit is rated for universal tool performance and targets primary workpiece materials including cast iron, non-ferrous metals, stainless steel, and steel. The screw machine length format provides a rigid, stub-style profile that minimizes deflection in production drilling scenarios. Its h8 shank diameter tolerance ensures a consistent fit in standard chucks and collets. The 3xD flute-to-diameter ratio supports efficient chip removal without coolant-through capability, making it appropriate for standard dry or flood-coolant setups on conventional and CNC equipment.

Key Features

• 130-degree split point reduces walking and lowers required thrust force
• Parabolic flute design promotes fast chip evacuation in deep or interrupted cuts
• Web-thinned, tapered web improves penetration in hard and abrasive materials
• Cobalt tool material provides heat and wear resistance beyond standard HSS
• h8 diameter tolerance on straight-cylindrical shank for precise chuck fit
• Conforms to DIN and ISO standards for dimensional consistency

Compatibility

Designed as an OEM-style screw machine length drill bit compatible with standard straight-shank drill chucks, keyless chucks, and collet systems accepting a 0.2031-inch (5.16 mm) shank diameter. Rated for use in cast iron, non-ferrous metal, stainless steel, and steel workpieces.

Installation Notes

Installation and use is performed by machinists and maintenance technicians using drill presses, CNC machining centers, or portable power drills. Secure the shank fully in the chuck to the rated grip depth before beginning any cut. Ensure the workpiece is properly fixtured and the machine is at a full stop before bit changes. Do not exceed the manufacturer-rated maximum drilling depth of 0.7087 inches per pass without retracting to clear chips.
