Walter-titex 5057050 Screw Machine Drill Bit 0.228 in

Product Description

The WALTER-TITEX 5057050 is a screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from cobalt and vanadium high speed steel, this bit delivers superior heat resistance and edge retention when cutting through hard and abrasive workpiece materials. It measures 0.228 inches in diameter with an overall length of 2-19/32 inches and features a 130-degree split point for accurate self-starting entry with minimal walking. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and extending tool life. A straight-cylindrical shank seats securely in standard drill chucks, and the bright uncoated finish suits a wide range of cutting fluid applications.

This drill bit is suited for screw machine operations, production drilling, and maintenance work across metalworking environments. The 3xD flute-to-diameter ratio and web-thinned tapered web configuration make it especially effective on difficult-to-machine materials including stainless steel, cast iron, hard alloys, and non-ferrous metals. It fits standard drill presses, CNC machines, and handheld power drills where a stub-length bit is preferred for rigidity. Licensed machinists, millwrights, and tool-and-die professionals will find it performs reliably in both light production and heavy shop use.

Key Features

• Cobalt and vanadium high speed steel construction for extended heat and wear resistance
• 130-degree split point reduces entry thrust and improves hole location accuracy
• Parabolic flute design accelerates chip evacuation during deep or interrupted cuts
• Web-thinned tapered web lowers cutting force on hard and stainless materials
• Screw machine length provides added rigidity compared to jobber-length bits
• Bright uncoated finish compatible with a broad range of cutting fluids and coolants

Compatibility

Designed for right-hand cut drilling into cast iron, hard material, non-ferrous metal, stainless steel, and steel. Fits standard straight-shank drill chucks used on drill presses, screw machines, and CNC equipment. Conforms to DIN, ISO, and BS specification designations per Series A1148.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with metal cutting operations. Secure the shank fully in the chuck and verify runout before drilling. Apply appropriate cutting fluid for the workpiece material, particularly when drilling stainless steel or hard alloys. Inspect the cutting edge for wear or chipping before each use and replace the bit if edge integrity is compromised.
