Walter-titex 5062943 Micro Drill Bit 1.45 Mm Cobalt

Product Description

The WALTER-TITEX 5062943 is a cobalt micro drill bit engineered for precision drilling in demanding materials. Built to DIN 1899 standards, it carries a 1.45 mm diameter with a straight-cylindrical shank of 1.50 mm and an overall length of 25.00 mm. The 118-degree standard point with web-thinned, tapered web geometry reduces entry force and improves centering accuracy. The bright, uncoated cobalt construction delivers heat resistance and edge retention without a surface coating that could affect tolerance in tight-clearance bores. Spiral fluting handles chip evacuation efficiently in short, confined cuts. This bit is intended for use by machinists, tool-and-die technicians, and precision fabricators working with micro-diameter holes.

The 5062943 is rated for blind hole, through hole, and stack drilling applications. Its primary workpiece materials are titanium alloys, with secondary suitability for glass and graphite. The 5xD flute-to-diameter ratio and 7.00 mm maximum drilling depth make it well-suited for shallow, precision bores in aerospace, medical, and specialty fabrication work where dimensional control and material integrity are critical. Right-hand cut orientation is standard for conventional CNC and manual drill press setups.

Key Features

• 1.45 mm drill diameter with a tight tolerance of +0.000 to -0.004 mm for precision bore sizing
• Cobalt tool material provides thermal resistance during drilling of titanium alloys and hard substrates
• 118-degree standard point with web-thinning for improved entry and reduced thrust force
• Spiral flute with regular helix promotes consistent chip evacuation in short-depth holes
• DIN 1899 specification ensures dimensional conformance and interchangeability
• Bright, uncoated finish maintains true diameter without coating buildup in micro-diameter bores

Compatibility

Designed for use in blind hole, stack drilling, and through hole drilling operations on titanium alloy workpieces, with secondary application on glass and graphite. Fits standard straight-shank collets and chucks accepting a 1.50 mm shank diameter. Part of WALTER-TITEX Series A3143.

Installation Notes

Installation and use should be performed by qualified machinists familiar with micro-diameter tooling. Secure the shank in a precision collet or drill chuck rated for 1.50 mm straight-cylindrical shanks before operation. Verify spindle runout is within tolerance before use, as micro drill bits are sensitive to radial error. Coolant-through is not supported on this bit; use external coolant or dry cutting practice appropriate for the workpiece material.
