Walter-titex 5057062 Screw Machine Drill Bit 0.161 in

Product Description

The WALTER-TITEX 5057062 is a screw machine length drill bit ground from Cobalt Vanadium High Speed Steel for high-performance drilling in demanding materials. It measures 0.161 inches (Wire Size 20) in diameter with an overall length of 2-5/32 inches and a flute length of 7/8 inch. The 130-degree split point with web thinning reduces thrust and centers the bit on contact, while the parabolic flute geometry promotes efficient chip evacuation. This bit is sold individually and carries a minimum order quantity of 5 units per order. Licensed trades and machining professionals rely on this geometry for production drilling in tight-tolerance applications.

The 5057062 is suited for drilling cast iron, hardened materials, non-ferrous metals, stainless steel, and carbon steel in both shop and field environments. Its screw machine length body fits standard drill chucks and CNC machining centers without extended reach, making it practical for high-cycle production work. The straight-cylindrical shank seats cleanly in Jacobs-style and precision collet chucks. The 3xD flute-to-diameter ratio supports a maximum drilling depth of 0.600 inches, keeping chips moving out of the hole during continuous feeds.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat resistance in hard and abrasive workpiece materials
• 130-degree split point with web thinning reduces walking and lowers feed force at entry
• Parabolic flute design improves chip flow and reduces packing in deep holes
• Bright/uncoated finish suitable for a wide range of cutting fluids and workpiece materials
• Tapered web configuration adds body strength while keeping cutting geometry consistent
• Conforms to DIN, ISO, and BS standards for dimensional and geometric accuracy

Compatibility

Designed as an OEM-style screw machine length drill bit in Series A1148, compatible with standard straight-cylindrical chuck systems and appropriate for universal drilling applications across cast iron, stainless steel, hard materials, and non-ferrous metals as specified by the manufacturer.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or trade professionals familiar with drill press, lathe, or CNC operation. Secure the straight-cylindrical shank fully in the chuck before operation and verify concentricity to minimize runout. Apply appropriate cutting fluid for the workpiece material, particularly when drilling stainless steel or hard alloys. Power down and de-energize the machine spindle completely before changing or inspecting the bit.
