Walter-titex 5062869 Micro Drill Bit 0.0138 in Cobalt

Product Description

The WALTER-TITEX 5062869 is a cobalt micro drill bit designed for precision drilling in demanding metalworking applications. Built to DIN 1899 specification, this bit features an M35 cobalt material grade, a 118-degree standard point angle, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The overall length is 25 millimeters with a spiral flute and a straight-cylindrical shank measuring 1.00 millimeter in diameter. The bright uncoated finish suits applications where coating buildup could compromise hole tolerance in small-diameter work. Licensed tradespeople and machining specialists rely on this geometry for repeatable, accurate results in tight-tolerance micro holes.

This micro drill bit is suited for drilling into a range of workpiece materials including aluminum silicon alloy, cast iron, copper alloy, German silver, malleable iron, sintered iron, and steel. Its 0.0138-inch diameter and 2.40-millimeter flute length make it appropriate for precision component work in manufacturing, toolroom, and maintenance machining environments. The right-hand cutting direction and regular spiral type are standard for conventional drill press and CNC operations requiring consistent micro-hole quality.

Key Features

• M35 cobalt construction for improved heat and wear resistance compared to standard HSS
• 118-degree standard point angle with web thinning for reduced entry force
• Tapered web configuration promotes efficient chip flow in short flute lengths
• DIN 1899 specification ensures dimensional consistency across the A3143 series
• Bright/uncoated finish maintains close diameter tolerance in precision micro-drilling
• Diameter tolerance held to +0.000 to -0.004 millimeters for accurate hole sizing

Compatibility

Designed for use with conventional drill presses, CNC machining centers, and precision hand-held drilling equipment that accept a 1.00-millimeter straight-cylindrical shank. Compatible workpiece materials include aluminum silicon alloy, cast iron, copper alloy, German silver, malleable iron, sintered iron, and steel.

Installation Notes

This bit is installed by machinists and toolroom technicians using equipment with a collet or precision chuck capable of holding a 1.00-millimeter straight shank securely. Ensure the spindle and workpiece are properly secured before operation to prevent deflection at this diameter. Use appropriate cutting fluid or dry-cutting practice as dictated by workpiece material and machine specifications. Micro drill bits are fragile at this diameter and should be run at manufacturer-recommended speeds and feeds to avoid breakage.
