Walter-titex 5062900 Micro Drill Bit Wire 71 Cobalt

Product Description

The WALTER-TITEX 5062900 is a cobalt micro drill bit designed for precision drilling in demanding materials. Built to DIN 1899 standards, this wire gauge size 71 bit measures 0.0260 inches (decimal inch) in diameter and carries a 118-degree standard point angle. The M35 cobalt construction delivers the heat resistance and edge retention needed when drilling titanium alloys, glass, and graphite. A web-thinned, tapered web geometry reduces thrust and improves centering at entry. The spiral flute with a 5xD flute-to-diameter ratio evacuates chips efficiently during both through-hole and blind-hole applications. Licensed HVAC, plumbing, and mechanical technicians, as well as precision machinists and fabricators, rely on this bit for high-accuracy micro-drilling work.

The 5062900 is suited for blind hole drilling, through-hole drilling, and stack drilling operations where tight tolerances and small diameters are required. Primary workpiece materials include titanium alloy, with secondary suitability for glass and graphite. The straight-cylindrical shank accepts standard collet chucks and drill press fixtures. With a 25 mm overall length and a 4.20 mm flute length, this bit is sized for shallow, precise entries in thin-section or layered workpieces. It is sold individually but carries a minimum order quantity of 10 units, making it appropriate for shop-stock replenishment.

Key Features

• M35 cobalt construction provides elevated heat resistance for titanium alloy and hard secondary materials
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust and accurate self-centering
• Wire gauge size 71 at 0.0260 inches decimal diameter with a tight tolerance of +0.000 to -0.004 mm
• Spiral flute with 5xD ratio supports chip evacuation in blind-hole and through-hole drilling
• Right-hand cut with bright/uncoated finish; no coolant-through feature required for typical micro-drilling depths
• Conforms to DIN 1899 specification for consistent dimensional and performance standards

Compatibility

Designed as a DIN 1899 Series A3143 micro drill bit for use in blind hole, through-hole, and stack drilling operations on titanium alloy (material codes K, N, P, S) and secondary materials including glass and graphite (material codes M, O). Fits any standard collet or chuck accepting a 1.00 mm straight-cylindrical shank.

Installation Notes

Installation and use of this micro drill bit should be performed by qualified machinists or trade professionals familiar with high-speed precision drilling equipment. Secure the straight-cylindrical shank fully in a collet or drill chuck rated for the spindle speed appropriate to a 0.0260-inch diameter cobalt bit before beginning any operation. Ensure the workpiece is clamped rigidly to minimize deflection at this diameter. Inspect the cutting edge for damage before each use, as micro drill bits at this diameter are susceptible to breakage if run at incorrect feeds, speeds, or entry angles.
