Walter-titex 5062852 Micro Drill Bit Wire 94 Cobalt

Product Description

The WALTER-TITEX 5062852 is a cobalt micro drill bit engineered for precision drilling in demanding materials. Built to DIN 1899 standards and manufactured from M35 cobalt steel, this bit carries a wire gauge size of 94, equivalent to 0.0071 inches in decimal diameter. The 118-degree standard point geometry paired with a web-thinned, tapered web configuration reduces entry force and improves centering on small-diameter holes. A bright, uncoated finish is standard. The spiral, regular-helix flute design promotes chip evacuation in short, confined flute lengths. Licensed technicians and precision machinists working with micro-diameter tooling will find this bit suited to tight-tolerance production and repair applications.

This drill bit is designed for blind hole, through hole, and stack drilling operations. Its primary workpiece material designation is titanium alloy, covering material codes K, N, P, and S. Secondary workpiece materials include glass and graphite. The 5xD flute-to-diameter ratio supports controlled penetration in thin and layered materials. With a straight-cylindrical shank of 1.00 mm diameter, it seats directly into compatible micro-chuck collets and precision drill presses used in aerospace, medical device, and electronics fabrication environments.

Key Features

• Wire size 94 with 0.0071-inch decimal diameter for micro-precision applications
• M35 cobalt steel construction for heat resistance in titanium alloy and hard materials
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust force
• Spiral flute with 5xD ratio supports chip clearance in blind and through hole drilling
• Straight-cylindrical shank, 1.00 mm diameter, for secure collet seating
• Manufactured to DIN 1899 specification with diameter tolerance of +0.000 to -0.004 mm
• Right-hand cut for use with standard clockwise-rotation spindles

Compatibility

Designed as an OEM-specification micro drill bit per DIN 1899 Series A3143, suited for use in precision drilling systems accepting a 1.00 mm straight-cylindrical shank. Rated for primary use in titanium alloy workpieces and secondary use in glass and graphite substrates.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die professionals familiar with micro-diameter tooling. Secure the shank fully in a precision collet or micro chuck before operation and verify runout with a dial indicator before drilling. At this diameter, excessive feed rate or lateral force will cause bit breakage. Coolant-through is not supported on this bit; use an appropriate external mist or flood coolant for titanium alloy applications where heat buildup is a concern.
