Walter-titex 5062879 Micro Drill Bit 0.45 Mm Cobalt

Product Description

The WALTER-TITEX 5062879 is a cobalt micro drill bit engineered for precision drilling in demanding materials. Built to DIN 1899 standards, it features a 0.45 mm diameter, a 118-degree standard point, and a web-thinned, tapered web design that reduces entry force and improves centering accuracy. The M35 cobalt steel construction resists heat buildup during high-speed drilling in tough alloys. With an overall length of 25.00 mm and a 1.00 mm straight-cylindrical shank, this bit fits standard micro-drill chucks and collets. It is sold individually and suited for precision machining shops, aerospace fabricators, and skilled trade professionals working at tight tolerances.

This micro drill bit is designed for blind hole, through-hole, and stack drilling operations. Its primary workpiece material rating covers titanium alloys and a range of ferrous and non-ferrous metals. It also handles secondary materials including glass and graphite where micro-drilling is required. The 5xD flute-to-diameter ratio and 3.00 mm flute length support chip evacuation in shallow, precise holes with a maximum drilling depth of 2.20 mm. The bright, uncoated finish maintains dimensional accuracy without added coating thickness, which matters at sub-millimeter diameters.

Key Features

• 0.45 mm diameter with a tight tolerance of +0.000 to -0.004 mm for precise hole sizing
• M35 cobalt steel construction for heat resistance in titanium alloys and hard metals
• 118-degree standard point with web-thinning for reduced thrust and accurate starts
• Spiral flute, right-hand cut for standard CNC and bench-drill applications
• DIN 1899 compliant construction for consistent dimensional quality
• Straight-cylindrical 1.00 mm shank fits standard micro-drill chucks and collets

Compatibility

Designed for use in Series A3143 micro-drilling applications. Rated for primary workpiece materials including titanium alloy and related material codes K, N, P, and S. Secondary material compatibility includes glass and graphite (codes M and O). Confirm spindle speed and feed rate recommendations for the specific workpiece material before use.

Installation Notes

This bit is installed by qualified machinists or precision drilling technicians using appropriate micro-drill chucks or collets rated for 1.00 mm shanks. Ensure the spindle and workpiece fixture are fully secured before operation. At sub-millimeter diameters, runout in the chuck or collet can cause premature breakage; verify chuck concentricity before use. Follow the machine manufacturer's recommended spindle speed and feed rates for cobalt tooling in the target material.
