Walter-titex 5062897 Micro Drill Bit 0.63 Mm Cobalt 118 Pt

Product Description

The WALTER-TITEX 5062897 is a cobalt micro drill bit engineered for precision drilling in small-diameter applications. Measuring 0.63 mm in diameter with an overall length of 25 mm, this bit features a 118-degree standard point and a web-thinned, tapered web configuration that reduces thrust and improves centering on entry. Built to DIN 1899 specification from M35-grade cobalt steel, it delivers the heat resistance and edge retention required when drilling hard or abrasive materials. Installation is performed by machinists and tooling technicians on CNC equipment, precision drilling machines, or similar tooling setups.

This micro drill bit is rated for blind hole, stack drilling, and through hole drilling applications. Primary workpiece materials include titanium alloy, with secondary suitability for glass and graphite. The right-hand spiral flute promotes efficient chip evacuation in these materials. The straight-cylindrical shank with a 1.00 mm shank diameter seats securely in standard micro collets and precision chucks. It is part of the Series A3143 lineup and carries a flute-to-diameter ratio of 5xD, supporting maximum drilling depths up to 3.10 mm.

Key Features

• M35-grade cobalt construction for heat resistance in titanium alloy and abrasive materials
• 118-degree standard point with web-thinned, tapered web for accurate entry and reduced thrust
• Bright/uncoated finish suitable for applications where coating interaction is a concern
• Right-hand spiral flute design promotes chip clearance in deep micro holes
• Straight-cylindrical 1.00 mm shank for compatibility with standard micro collets
• Conforms to DIN 1899 specification for dimensional consistency

Compatibility

Designed for use in blind hole, stack drilling, and through hole drilling operations on titanium alloy as the primary workpiece material, with secondary compatibility for glass and graphite workpieces. Part of Walter-Titex Series A3143.

Installation Notes

This bit is installed by qualified machinists or tooling technicians in precision drilling equipment. Ensure the spindle and collet are clean and free of debris before seating the shank. Verify that spindle speed and feed rate settings are appropriate for the workpiece material and drill diameter before operation. No coolant-through feature is present on this bit; apply external coolant or cutting fluid as required by the machining operation.
