Walter-titex 5337197 Cobalt Screw Machine Drill Bit 0.0635 in

Product Description

The WALTER-TITEX 5337197 is a screw machine length cobalt drill bit designed for high-performance drilling in demanding materials. Built to DIN 1897 specification, this bit measures 0.0635 inches (Wire Size 52) in diameter with a 130-degree conical point for aggressive, self-centering entry. The M35 cobalt material grade provides heat resistance and edge retention when cutting through abrasive or work-hardening materials. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup during continuous drilling operations. At 1.3386 inches overall length, this screw machine length format suits drill presses, CNC machines, and handheld power tools in close-tolerance applications where a shorter-than-jobber-length bit is required.

This bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and carbon steel in both production and maintenance environments. The straight-cylindrical shank seats securely in standard chucks without slippage. Its universal tool performance rating makes it a practical choice for metal fabrication shops, aerospace component work, and MRO applications where a small-diameter, short-length bit handles tight-clearance drilling or pilot hole operations. The right-hand cut and tapered web configuration are standard for general-purpose drilling in horizontal or vertical orientations.

Key Features

• M35 cobalt construction for extended tool life in stainless steel and hard alloys
• 130-degree conical point for fast, self-centering penetration
• Parabolic flute design improves chip flow and reduces heat at the cutting edge
• Screw machine (stub) length at 1.3386 inches overall for rigid, low-deflection drilling
• Straight-cylindrical shank with h8 diameter tolerance for accurate chuck fitment
• Meets DIN 1897 and ISO standards for dimensional consistency

Compatibility

Designed as an OEM-specification replacement drill bit for applications requiring a Wire Size 52 screw machine length bit per DIN 1897 and ISO standards. Compatible with any standard drill chuck accepting a 1.61 mm straight-cylindrical shank.

Installation Notes

This bit is installed and operated by machinists, tool-and-die technicians, and maintenance professionals using drill presses, CNC machining centers, or handheld power drills. Ensure the chuck is fully tightened and the shank is fully seated before operation. When drilling stainless steel or hardened alloys, use appropriate cutting fluid to manage heat and extend bit life. Inspect the cutting edges for wear before each use, as cobalt bits can chip if run at incorrect speeds or feeds.
