Walter-titex 5062861 Cobalt Micro Drill Bit 0.27mm 118pt

Product Description

The WALTER-TITEX 5062861 is a cobalt micro drill bit engineered for precision drilling in demanding industrial and machining applications. Built to DIN 1899 standards, this bit features a 0.27 mm diameter, a 118-degree standard point angle, and a web-thinned, tapered web configuration that reduces entry resistance and improves centering accuracy. The M35 cobalt construction provides elevated heat resistance compared to standard high-speed steel, making it suitable for harder and more abrasive workpiece materials. With a bright, uncoated finish and a right-hand spiral flute, this bit delivers clean chip evacuation and consistent performance in high-tolerance work. It is typically installed and operated by machinists, tool-and-die makers, and precision fabricators.

The 5062861 is rated for blind hole, through hole, and stack drilling operations. Its primary workpiece material designations cover titanium alloys and a broad range of metals in the K, N, P, and S material groups. Secondary applications include glass and graphite. The straight-cylindrical shank with a 1.00 mm shank diameter fits standard micro drill chucks and collet systems. The 5xD flute-to-diameter ratio supports controlled drilling depths appropriate to the bit size.

Key Features

• M35 cobalt construction for improved heat and wear resistance in hard materials
• 118-degree standard point with web-thinned, tapered web for accurate entry and reduced thrust force
• Right-hand spiral flute design promotes efficient chip removal
• Bright, uncoated finish suitable for dry and lubricated drilling conditions
• Conforms to DIN 1899 specification for consistent dimensional tolerance
• Diameter tolerance of +0.000 to -0.004 mm for close-tolerance hole sizing

Compatibility

Designed for use in precision drilling of titanium alloys and metals in material groups K, N, P, and S, with secondary suitability for glass and graphite. Fits micro drill chucks and collet holders accepting a 1.00 mm straight-cylindrical shank.

Installation Notes

This micro drill bit should be installed and operated by qualified machinists familiar with micro-drilling procedures. Verify chuck or collet runout before use, as any eccentricity at this diameter can cause immediate bit breakage. Power down and de-energize the drilling machine before changing tooling. Follow applicable workplace safety standards and the machine manufacturer guidelines for spindle speed and feed rate selection appropriate to the workpiece material.
