Walter-titex 5057148 Screw Machine Drill Bit 15/64 in

Product Description

The WALTER-TITEX 5057148 is a screw machine length drill bit engineered for high-performance drilling in a range of metallic workpiece materials. It features a 15/64 inch (0.2344 inch decimal) diameter and a 130-degree split point that reduces walking and minimizes the need for a center punch. The parabolic flute geometry promotes fast chip evacuation, making it well-suited for deeper holes in gummy or stringy materials. Constructed from vanadium high speed steel with a bright uncoated finish, the 5057148 delivers solid wear resistance without the added cost of a surface coating. It is sized at 2-19/32 inches overall length and carries a right-hand cutting direction, consistent with standard drill press and handheld power tool use by machinists, maintenance technicians, and metalworking tradespeople.

This bit is designed for use in screw machine length applications where a shorter, more rigid tool is preferred over jobber-length drill bits. Primary workpiece materials include aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel. The parabolic flute and web-thinned, tapered web configuration make it particularly effective in high-feed drilling operations where chip clearance and point stability are critical. It fits standard straight-cylindrical shank tool holders and drill chucks used in bench drill presses, CNC drilling operations, and handheld power drills.

Key Features

• 15/64 inch (0.2344 inch) diameter with tight tolerance of -0.00071 to 0.00000 inches
• 130-degree split point reduces thrust and eliminates center-punch requirements on most metals
• Parabolic flute design accelerates chip evacuation in deep-hole drilling
• Web-thinned tapered web improves cutting efficiency and reduces heat buildup at the tip
• Vanadium high speed steel construction rated for high-performance grade applications
• Bright uncoated finish suits general-purpose metalworking without coating incompatibility concerns
• Straight-cylindrical shank fits standard drill chucks without special toolholding equipment

Compatibility

Compatible with aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel workpieces as specified by the manufacturer. Fits standard straight-cylindrical shank drill chucks. Part of the WALTER-TITEX Series A1148, conforming to BS and DIN specification designations.

Installation Notes

This drill bit is installed and operated by machinists, tool-and-die technicians, and maintenance tradespeople using standard drill presses, CNC machines, or power drills equipped with a compatible chuck. Ensure the workpiece is securely clamped before drilling to prevent rotation or movement. Use appropriate cutting fluid for stainless steel and harder alloys to manage heat and extend tool life. Inspect the split point for chipping or wear before each use, as a damaged point will reduce hole accuracy and increase thrust force.
