Walter-titex 5062923 Micro Drill Bit Size 65 Cobalt

Product Description

The WALTER-TITEX 5062923 is a cobalt micro drill bit designed for precision drilling in demanding materials at extremely small diameters. Built to DIN 1899 standards, this bit carries a wire gauge size of 65, measuring 0.0350 inches (0.89 mm) in diameter, with a 1.50 mm straight-cylindrical shank and an overall length of 25 mm. The 118-degree standard point angle and spiral flute geometry make it well suited for controlled entry and chip evacuation in tight-tolerance applications. The bright, uncoated cobalt construction provides the heat resistance needed when working through hard or abrasive workpiece materials. Licensed machinists, tool-and-die technicians, and precision fabricators rely on this type of bit for repeatable, burr-minimized results in production environments.

The 5062923 is rated for blind hole, through hole, and stack drilling operations. Its primary workpiece materials are titanium alloy and similar high-strength alloys, with secondary suitability for glass and graphite. The 6.00 mm flute length and 4.50 mm maximum drilling depth keep this bit focused on shallow, high-precision passes rather than deep-bore applications. With a 5xD flute-to-diameter ratio and a web-thinned, tapered web configuration, it delivers consistent performance in short-run and production-quantity drilling where dimensional accuracy is critical.

Key Features

• Wire gauge size 65 (0.0350 inches) with a diameter tolerance of +0.000 to -0.004 mm for tight-fit applications
• Cobalt tool material provides elevated heat resistance compared to standard high-speed steel
• 118-degree standard point angle suitable for a wide range of metallic and composite workpiece materials
• Web-thinned, tapered web configuration reduces thrust force and improves hole entry accuracy
• Spiral flute with right-hand cut promotes efficient chip evacuation in blind and through hole drilling
• Conforms to DIN 1899 specification for consistent dimensional standards across the Series A3143 line

Compatibility

Rated for use in titanium alloy as the primary workpiece material, with secondary compatibility for glass and graphite. Material codes K, N, P, and S (primary) and M and O (secondary) per the supplier classification. Designed for use in CNC machining centers, drill presses, and precision hand-held equipment capable of maintaining the close tolerances required by a 0.0350-inch micro drill.

Installation Notes

Micro drill bits of this diameter require a precision collet or chuck capable of holding a 1.50 mm shank without runout. Always verify spindle speed and feed rate against the workpiece material before drilling to avoid bit breakage at this diameter. Power down or de-energize the machine spindle completely before changing tooling. Coolant-through is not supported on this bit; use appropriate external lubrication or dry-cutting technique as required by the workpiece material.
