Walter-titex 5057539 Screw Machine Drill Bit 1/16 in

Product Description

The WALTER-TITEX 5057539 is a solid carbide screw machine length drill bit designed for precision drilling in hard and abrasive materials. Built to Series A1163 specifications and compliant with DIN 6539 and ISO standards, this bit features a 118-degree point angle, a two-flute right-hand spiral, and a bright uncoated finish. With an overall length of 1.34 inches and a 1/16 inch (0.0630 inch) diameter, it is sized for close-tolerance work requiring a short, rigid cutting tool. The h7 diameter tolerance ensures consistent fit in collets and chucks. Licensed HVAC technicians, machinists, and trade professionals performing precision hole work in brittle or composite substrates will find this bit suited to demanding production and service applications.

This drill bit is engineered for general purpose drilling in primary workpiece materials including glass and graphite. Its screw machine length body provides enhanced rigidity compared to jobber-length bits, making it well-suited for CNC machining centers, drill presses, and handheld operations where deflection control is critical. The straight-cylindrical shank diameter of 0.0630 inches fits standard collet chucks and keyless drill chucks designed for small-diameter tooling. Maximum drilling depth is 0.28 inches, with a flute length of 0.39 inches.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive materials such as glass and graphite
• 118-degree point angle for general purpose entry geometry
• Screw machine length body reduces deflection in short-reach drilling applications
• Right-hand cut, two-flute spiral design promotes chip evacuation in brittle substrates
• Bright uncoated finish — no coating buildup risk on small-diameter cutting edges
• h7 diameter tolerance for consistent, repeatable chuck or collet seating
• Meets DIN 6539 and ISO standards

Compatibility

Designed as a general purpose screw machine length drill bit for use in standard straight-shank collet chucks and keyless drill chucks accepting 1/16 inch diameter tooling. Verified primary workpiece materials are glass and graphite per manufacturer specification.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or trade professionals familiar with small-diameter carbide tooling. Secure the straight-cylindrical shank fully in the collet or chuck before operation to prevent runout or bit breakage. Carbide is brittle — avoid side loading, impact, or flex that would be tolerated by high-speed steel bits. Inspect the cutting edges for chipping before each use, as solid carbide micro-drill bits are susceptible to damage from improper handling or storage.
