Walter-titex 5057064 Screw Machine Drill Bit 0.157 in

Product Description

The WALTER-TITEX 5057064 is a screw machine length drill bit ground from Cobalt Vanadium High Speed Steel for high-performance drilling in demanding materials. The bit measures 0.157 inches (No. 22 wire gauge) in diameter with an overall length of 2-5/32 inches and a flute length of 7/8 inches. A 130-degree split point reduces walking on entry and decreases thrust force, while the parabolic flute geometry improves chip evacuation and extends tool life. The bright, uncoated finish makes it easy to inspect for wear. This bit is designed for licensed machinists, tool-and-die professionals, and HVAC or mechanical contractors who routinely drill tight-tolerance holes in hard and abrasive materials.

The 5057064 is suited for production drilling in cast iron, stainless steel, carbon steel, hard alloys, and non-ferrous metals. Its screw machine length body provides added rigidity in drill press, CNC mill, and turret lathe applications where stub-length control is preferred over jobber-length reach. The 3xD flute-to-diameter ratio supports chip clearance in short, interrupted cuts typical of sheet metal stacks and structural components. The straight-cylindrical shank fits standard drill chucks without adapters.

Key Features

• Cobalt Vanadium HSS construction for heat resistance and edge retention in hard and abrasive workpieces
• 130-degree split point with web thinning reduces entry thrust and prevents bit walk
• Parabolic flute profile with tapered web configuration accelerates chip removal
• Screw machine (stub) length body increases rigidity and reduces deflection
• Right-hand cut, straight-cylindrical shank fits standard drill chucks directly
• Meets DIN, ISO, and BS standards; Series A1148 designation for OEM and replacement sourcing

Compatibility

Designed for use in drill presses, CNC machining centers, turret lathes, and hand-held drilling equipment accepting a straight-cylindrical shank. Primary workpiece materials include cast iron, stainless steel, carbon steel, hard alloys, and non-ferrous metals.

Installation Notes

Secure the shank fully in the chuck and confirm runout is within acceptable tolerance before drilling. Power down and de-energize all equipment before changing tooling. Follow applicable ANSI and shop-safety guidelines for rotating cutting tools. Do not exceed the recommended maximum drilling depth of 0.600 inches per pass without retracting to clear chips.
