Walter-titex 5057203 Screw Machine Drill Bit 0.2087in

Product Description

The WALTER-TITEX 5057203 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from Cobalt Vanadium High Speed Steel, this bit delivers the hardness and heat resistance required when working through stainless steel, cast iron, hard materials, and non-ferrous metals. The 130-degree split point starts on contact without walking, and the parabolic flute geometry clears chips efficiently at depth. With an overall length of 2-7/16 inches and a straight-cylindrical shank, it seats securely in standard drill chucks and machine spindles. This is a high-performance grade bit intended for production and maintenance machinists who need consistent, repeatable hole quality.

The 5057203 is rated for use across a broad range of primary workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Its universal tool performance rating and 3xD flute-to-diameter ratio make it suitable for CNC machining centers, drill presses, and screw machine operations in both shop and field maintenance environments. The bright, uncoated finish is appropriate for a wide range of cutting fluids or dry drilling setups depending on the base material. This bit is sold individually per package, with a minimum order quantity of 10 units.

Key Features

• Cobalt Vanadium High Speed Steel construction for elevated heat and wear resistance in hard materials
• 130-degree split point reduces thrust and eliminates center-punch requirements on most metals
• Parabolic flute geometry with web thinning improves chip evacuation and reduces cutting torque
• Tapered web configuration with web-thinned geometry extends tool life in production drilling
• Screw machine length (2-7/16 inches overall) provides rigidity and reduced deflection at the cutting zone
• Meets DIN, ISO, and BS standards for dimensional accuracy and tool geometry

Compatibility

Designed as a Series A1148 screw machine length drill bit suitable for use in CNC machining centers, drill presses, and turret lathes equipped with standard straight-shank toolholders or chucks accepting a 0.2087-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the straight-cylindrical shank fully in a properly sized chuck or collet before operation, and verify spindle runout is within acceptable limits to maintain the stated diameter tolerance of -0.00071 to 0.00000 inches. Always power down and lock out the machine before changing or inspecting bits. Follow applicable shop safety standards and use appropriate cutting fluid or coolant for the workpiece material being drilled.
