Walter-titex 5057147 Screw Machine Drill Bit 15/32 in

Product Description

The WALTER-TITEX 5057147 is a screw machine length drill bit designed for high-performance metal drilling in industrial and trade applications. Built from Vanadium High Speed Steel with a bright, uncoated finish, this bit features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduced heat buildup. The overall length is 4-1/32 inches with a 2-inch flute length, making it well-suited for close-quarters drilling where a jobber-length bit would not fit. Machinists, tool-and-die techs, and maintenance trades install this bit in drill presses, CNC machines, and hand-held power drills.

This drill bit is optimized for use on a wide range of workpiece materials including aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel. Its screw machine length profile and straight-cylindrical shank make it a practical choice for production drilling, fixture work, and precision hole-making where rigidity and stub-length stability matter. The web-thinned, tapered web configuration reduces thrust and improves centering, particularly in interrupted cuts and cross-drilled applications.

Key Features

• 130-degree split point improves self-centering and reduces walking on entry
• Parabolic flute design accelerates chip removal and lowers cutting temperature
• Web-thinned tapered web reduces axial thrust for easier penetration
• Vanadium High Speed Steel construction provides hardness and wear resistance across rated workpiece materials
• Straight-cylindrical shank fits standard three-jaw drill chucks and collets
• Screw machine length body adds rigidity over jobber-length bits in confined setups

Compatibility

Rated for drilling aluminum alloy, aluminum silicon alloy, brass, copper alloy, stainless steel, and steel. Part of WALTER-TITEX Series A1148. Conforms to BS and DIN specification designations. Fits any standard drill chuck or collet sized for a 15/32-inch straight-cylindrical shank.

Installation Notes

This bit is installed and replaced by machinists, tool-and-die technicians, and maintenance mechanics. Secure the shank fully in the chuck or collet before use and verify runout is within acceptable limits. Use appropriate cutting fluid or coolant for stainless steel and copper alloys to extend tool life, noting this bit does not support through-coolant delivery. Follow machine manufacturer guidelines for spindle speed and feed rate based on workpiece material.
