Walter-titex 5062883 Micro Drill Bit 0.49 Mm Cobalt

Product Description

The WALTER-TITEX 5062883 is a cobalt micro drill bit engineered for precision drilling in demanding materials. Built to DIN 1899 standards, this M35 cobalt-grade bit features a 0.49 mm diameter with a 118-degree standard point angle and a web-thinned, tapered web configuration for consistent centering and reduced thrust on entry. The straight-cylindrical shank measures 1.00 mm in diameter, and the overall length is 25.00 mm, making it well suited for confined, close-tolerance work. With a spiral flute and right-hand cut geometry, it delivers clean chip evacuation in both blind and through-hole applications. Licensed HVAC techs, machinists, and precision fabricators working with titanium alloys and similar hard metals rely on this bit for repeatable results at micro-scale diameters.

This micro drill bit is designed for blind hole drilling, through-hole drilling, and stack drilling operations. Its primary workpiece materials are titanium alloys and other high-strength metals classified under material codes K, N, P, and S. Secondary applications include glass and graphite (material codes M and O). The 5xD flute-by-diameter ratio and a maximum drilling depth of 2.60 mm support controlled penetration in layered or stacked workpieces. This bit is a fit for precision shops, aerospace fabrication, and trade professionals working with thin or hard substrates that demand micro-diameter tooling.

Key Features

• M35 cobalt material grade for heat and wear resistance in titanium alloy and hard material drilling
• 118-degree standard point angle with web-thinned, tapered web for accurate entry and reduced walking
• Right-hand spiral flute geometry promotes efficient chip evacuation in blind and through-hole work
• Straight-cylindrical 1.00 mm shank fits standard micro-drill chucks and collet holders
• Bright/uncoated finish maintains dimensional accuracy to DIN 1899 tolerance of +0.000 to -0.004 mm
• Suitable for blind hole, through hole, and stack drilling applications

Compatibility

Designed as an OEM-style replacement or direct-application micro drill bit conforming to DIN 1899 Series A3143, suitable for use in precision drilling of titanium alloys, glass, and graphite across blind hole, through hole, and stack drilling setups.

Installation Notes

Installation and use of micro drill bits at this diameter should be performed by qualified machinists or precision fabricators using a drill press, CNC machining center, or micro-drill station with appropriate speed and feed settings for cobalt tooling in the target material. Secure the workpiece firmly before drilling to prevent bit deflection or breakage at this micro diameter. Always power down and lock out the machine spindle before changing bits. Do not exceed the maximum drilling depth of 2.60 mm in a single pass without clearing chips to prevent bit breakage.
