Walter-titex 5062938 Micro Drill Bit 1.2 Mm Cobalt

Product Description

The WALTER-TITEX 5062938 is a cobalt micro drill bit engineered for high-precision drilling in demanding materials. Built to DIN 1899 standards, this bit features a 1.2 mm diameter, a 118-degree standard point angle, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at small diameters. The straight-cylindrical shank measures 1.5 mm, the overall length is 25 mm, and the spiral flute length is 8.5 mm. The bright, uncoated cobalt construction delivers reliable performance in titanium alloys and other difficult-to-machine materials. This tool is suited for precision metalworking tradespeople, tool-and-die shops, and aerospace maintenance technicians who require tight-tolerance micro-drilling.

This micro drill bit is designed for blind hole, stack drilling, and through-hole drilling applications. Its primary workpiece materials are titanium alloys along with materials rated under material codes K, N, P, and S. Secondary workpiece materials include glass and graphite. The 5xD flute-to-diameter ratio and right-hand cut spiral flute geometry support controlled chip removal in both shallow and deeper micro-bore operations. A maximum drilling depth of 6 mm makes it appropriate for precision component work in aerospace, electronics, and fine mechanical assemblies.

Key Features

• Cobalt construction rated for titanium alloy and hard material drilling
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust
• 1.2 mm diameter with a diameter tolerance of +0.000 to -0.004 mm for tight-tolerance work
• Spiral flute, right-hand cut geometry for efficient chip evacuation
• Straight-cylindrical 1.5 mm shank for secure chuck retention in micro drilling equipment
• Manufactured to DIN 1899 specification, Series A3143

Compatibility

Designed as a DIN 1899-compliant micro drill bit for use in precision drilling applications involving titanium alloys, glass, and graphite workpieces. Compatible with standard straight-shank micro drill chucks accepting a 1.5 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or precision metalworking technicians familiar with micro-drilling operations. Secure the 1.5 mm straight-cylindrical shank fully in a matched micro drill chuck before operation and verify runout before engaging the workpiece. Power down and de-energize the spindle before bit changes. Do not exceed the 6 mm maximum drilling depth rating, and avoid side loading, which can cause breakage at this diameter.
