Walter-titex 5057063 Screw Machine Drill Bit 0.159 in

Product Description

The WALTER-TITEX 5057063 is a screw machine length drill bit designed for high-performance drilling in demanding materials. Built from cobalt vanadium high speed steel with a bright uncoated finish, this bit handles cast iron, stainless steel, hard materials, non-ferrous metals, and general steel. It carries a 130-degree split point angle with web thinning for fast penetration and reduced thrust. The parabolic flute geometry promotes efficient chip evacuation in short-length drilling applications. At 2-5/32 inches overall length with a 7/8-inch flute length, it fits standard screw machine drill configurations. This bit belongs to the Series A1148 and meets DIN, ISO, and BS standards. Licensed machinists, tool and die technicians, and maintenance professionals rely on this type of bit for precision hole work in tight-tolerance environments.

This drill bit is suited for use in CNC screw machines, drill presses, and hand-held power tools where stub-length bits are required for rigidity and accuracy. Its universal tool performance rating means it is appropriate for a wide range of workpiece materials including stainless steel, cast iron, and non-ferrous metals. The straight-cylindrical shank provides secure chuck engagement in standard 3-jaw and keyless chucks. Wire size 21 designation (0.1590 decimal inch) makes it a common selection for tapping and clearance hole applications in metalworking and fabrication shops.

Key Features

• Cobalt vanadium high speed steel construction for extended tool life in hard and abrasive materials
• 130-degree drill point angle with web thinning and tapered web configuration for reduced entry thrust
• Parabolic flute geometry promotes aggressive chip evacuation at a 3xD flute-to-diameter ratio
• Right-hand cut with straight-cylindrical shank for standard chuck compatibility
• Screw machine (stub) length provides added rigidity and reduced deflection in short-reach applications
• Meets DIN, ISO, and BS standards; rated high performance grade for universal workpiece materials

Compatibility

Designed as an OEM-style replacement and standard-duty drill bit for screw machine and drill press applications requiring a wire size 21 (0.1590 inch) straight-shank stub-length bit compatible with DIN and ISO tooling standards.

Installation Notes

This bit is installed by machinists and metalworking technicians using standard drill press, CNC screw machine, or hand-held power tool setups. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck key is removed before powering the machine. Use appropriate cutting fluid or coolant for stainless steel and hard material applications to manage heat buildup, noting this bit does not support through-coolant delivery. Inspect the cutting edges before each use and replace if chipping or dulling is observed to maintain hole tolerance.
