Walter-titex 5057081 Screw Machine Drill Bit 0.1015 in

Product Description

The WALTER-TITEX 5057081 is a screw machine length drill bit ground from Cobalt Vanadium High Speed Steel (HSS-Co) for demanding drilling applications. At 0.1015 inches in diameter, the bit features a 130-degree split point and a parabolic flute geometry that promotes chip evacuation and reduces walking on entry. The overall length is 1-11/16 inches, making it compact enough for tight-clearance work in drill presses, CNC machining centers, and hand-held power tools. Web thinning and a tapered web configuration reduce thrust requirements when drilling hard or abrasive materials. Right-hand cut. Series A1148.

This bit is suited for production and maintenance drilling in ferrous and non-ferrous metals including steel, stainless steel, cast iron, and hard alloys. The screw machine length format is a common choice when rigidity and runout control matter more than reach. Maximum recommended drilling depth is 0.40 inches (10.00 mm), consistent with the 3xD flute-to-diameter ratio. It is used by machinists, tool-and-die professionals, and maintenance technicians working on metal fabrication, equipment repair, and precision assembly applications.

Key Features

• Cobalt Vanadium High Speed Steel construction for extended tool life in hard and abrasive materials
• 130-degree split point reduces thrust and improves self-centering on entry
• Parabolic flute profile accelerates chip removal and reduces heat buildup
• Web-thinned tapered web lowers cutting resistance on harder workpieces
• Bright/uncoated finish compatible with standard cutting fluids and oils
• Manufactured to DIN, ISO, and BS standards for dimensional consistency

Compatibility

Designed for drilling cast iron, hard materials, non-ferrous metals, stainless steel, and steel. Fits any standard straight-shank chuck accepting 0.1015-inch shanks. Conforms to DIN, ISO, and BS specifications as noted in Series A1148.

Installation Notes

Installation and use of this bit is performed by machinists or maintenance technicians operating drill presses, CNC equipment, or portable power drills. Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation and verify runout before starting a production run. Use an appropriate cutting fluid or oil when drilling stainless steel or hard alloys to manage heat and extend tool life. Do not exceed the maximum drilling depth of 0.40 inches without retracting to clear chips.
