Walter-titex 5062914 Cobalt Micro Drill Bit 0.8 Mm 118 Point

Product Description

The WALTER-TITEX 5062914 is a cobalt micro drill bit engineered for precision drilling in demanding materials. Built to DIN 1899 standards, it features a 0.8 mm (0.0315 inch) diameter with a straight-cylindrical shank measuring 1.50 mm in diameter. The 118-degree standard point geometry, combined with a web-thinned, tapered web configuration, reduces entry force and improves centering accuracy. Overall length is 25.00 mm with a spiral flute length of 5.30 mm. Maximum drilling depth reaches 4.00 mm (0.2000 inch). The bright, uncoated cobalt construction provides heat resistance without the brittleness associated with carbide tooling, making this bit a reliable choice for tight-tolerance micro-drilling operations.

The 5062914 is suited for blind hole, stack drilling, and through-hole drilling applications. Its primary workpiece material rating covers titanium alloys and a broad range of ferrous and non-ferrous metals. Secondary applications include glass and graphite. Right-hand cut spiral flutes evacuate chips efficiently, reducing heat buildup in thin-section and stacked workpieces. This bit is used in precision machining, aerospace fabrication, and industrial maintenance environments where dimensional accuracy at small diameters is critical.

Key Features

• Cobalt tool material for elevated heat resistance in hard and abrasive workpieces
• 118-degree standard point with web thinning for improved centering and reduced thrust force
• DIN 1899 specification compliance ensures dimensional consistency
• Diameter tolerance of +0.000 to -0.004 mm supports tight-tolerance applications
• Right-hand cut spiral flutes promote efficient chip evacuation in blind and through-hole drilling
• 5xD flute-to-diameter ratio provides adequate chip clearance at this micro diameter

Compatibility

Designed for use in drilling titanium alloys, ferrous metals, glass, and graphite as noted by material codes K, N, P, S, M, and O. Rated for blind hole, stack drilling, and through-hole drilling operations within a maximum depth of 4.00 mm.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with micro-diameter drill bits. Secure the bit in a precision collet or chuck rated for the 1.50 mm shank diameter to prevent runout at this scale. Ensure the spindle and workpiece fixturing are fully secured before operation, as micro drill bits are susceptible to breakage under lateral loading. Follow the machine tool manufacturer guidelines for feed rate and spindle speed when working with cobalt tooling in titanium and hard alloy materials.
