Walter-titex 5057223 Screw Machine Drill Bit 0.2756 in

Product Description

The WALTER-TITEX 5057223 is a screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built from cobalt and vanadium high speed steel, this bit delivers the hardness and heat resistance needed when cutting through stainless steel, cast iron, hard materials, and non-ferrous metals. The 130-degree split point reduces walking at entry and lowers thrust force, while the parabolic flute geometry promotes efficient chip evacuation. At 0.2756 inches in diameter with an overall length of 2-29/32 inches, this bit fits standard screw machine drilling setups and is suited for use by machinists, maintenance technicians, and fabricators working in production or job-shop environments.

The 5057223 is built for universal tool performance across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Its screw machine length profile makes it well suited for CNC drilling centers, turret lathes, and bench drill press operations where rigidity and short flute-to-diameter ratios improve hole accuracy. The straight-cylindrical shank fits standard drill chucks without adapters. With a maximum drilling depth of 0.9000 inches and a 3xD flute-by-diameter ratio, this bit is appropriate for through-holes and shallow blind holes in production environments.

Key Features

• Cobalt and vanadium high speed steel construction for elevated heat and wear resistance
• 130-degree split point with web thinning reduces entry thrust and prevents bit walking
• Parabolic flute profile improves chip flow and reduces clogging during deep cuts
• Tapered web configuration adds rigidity along the cutting length
• Bright uncoated finish suitable for use with cutting fluid on ferrous and non-ferrous materials
• Conforms to DIN, ISO, and BS standards for dimensional consistency and interchangeability

Compatibility

Designed for use in standard drill chucks accepting a straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Series A1148, with a drill bit size range of 0.2500 to 0.3000 inches decimal inch.

Installation Notes

This drill bit is installed by qualified machinists or maintenance technicians using a standard drill chuck on CNC equipment, turret lathes, or drill presses. Ensure the machine is fully powered down and the chuck is secured before bit changes. Use appropriate cutting fluid for the workpiece material, particularly when drilling stainless steel or hard materials, to manage heat buildup and extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is visible.
