Walter-titex 5057158 Screw Machine Drill Bit 19/64 in

Product Description

The WALTER-TITEX 5057158 is a screw machine length drill bit designed for high-performance drilling in a range of metallic workpiece materials. Built from vanadium high speed steel with a bright, uncoated finish, it features a 130-degree split point and parabolic flute geometry for efficient chip evacuation and reduced thrust. The straight-cylindrical shank measures 19/64 inches in diameter (0.2969 inches decimal), and the overall length is 3.125 inches. A web-thinned, tapered web configuration supports accurate starting and cleaner hole entry. This bit is suited for production drilling environments where precision and repeatability are required.

The 5057158 is used in screw machine operations and general metalworking applications across residential and commercial shops, as well as maintenance and repair settings. Its primary workpiece materials include aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel. The right-hand cutting direction is standard for conventional drill press and CNC spindle setups. Machinists, tool-and-die tradespeople, and maintenance technicians working with short-hole drilling applications will find this bit appropriate for their workflow.

Key Features

• Vanadium high speed steel construction for durability in metalworking applications
• 130-degree split point reduces walking and improves hole accuracy at entry
• Parabolic flute geometry promotes fast chip evacuation, especially in aluminum and soft alloys
• Web-thinned tapered web reduces cutting resistance and axial thrust
• Screw machine (stub) length provides added rigidity compared to jobber-length bits
• Meets BS and DIN specification designations

Compatibility

Designed for use with aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel workpieces. Fits any drill press, screw machine, or CNC spindle accepting a straight-cylindrical shank in the 19/64-inch diameter range. Part of the WALTER-TITEX Series A1148.

Installation Notes

This bit is installed and serviced by machinists, toolroom technicians, and maintenance tradespeople. Secure the straight-cylindrical shank firmly in a matching collet or drill chuck before operation. Inspect the cutting edges and web area for wear or chipping before each use and replace if the split point shows degradation. No coolant-through capability is present on this bit, so apply external cutting fluid as appropriate for the workpiece material to manage heat buildup.
