Walter-titex 5057142 Screw Machine Drill Bit 14mm Cobalt Hss

Product Description

The WALTER-TITEX 5057142 is a screw machine length drill bit designed for high-productivity hole-making in demanding materials. Built from M35-grade Cobalt Vanadium High Speed Steel, it handles cast iron, stainless steel, hard materials, non-ferrous metals, and general steel without coating. The 130-degree conical point with U-grind geometry and web-thinned, tapered-web construction reduces entry force and improves centering. The parabolic flute profile clears chips efficiently over a 54 mm flute length. At 107 mm overall length, this is a stub-length format suited for rigid setups where a standard jobber length would flex or deflect.

This drill bit is suited for production and maintenance applications in machining environments where short, rigid tooling is preferred. The straight-cylindrical shank at 14.00 mm diameter seats directly in drill chucks and collet holders without adapters. Its universal tool performance rating makes it appropriate for manual drill presses, CNC machining centers, and turret lathes. Typical users include machinists, tool-and-die technicians, and maintenance mechanics working with structural steel, stainless fabrications, and cast components.

Key Features

• M35 Cobalt Vanadium HSS construction resists heat buildup when drilling hard and abrasive materials
• 130-degree conical point with U-grind and web thinning reduces thrust force at entry
• Parabolic flute geometry improves chip evacuation in deep-hole and interrupted-cut conditions
• Bright uncoated finish allows easy visual inspection of wear and regrinding without coating interference
• Screw machine (stub) length format maximizes rigidity and reduces deflection in short-reach applications
• Conforms to DIN 1897 specification with h8 diameter tolerance for consistent fit in standard toolholders

Compatibility

Designed as a DIN 1897 screw machine length drill bit in Series A1148, compatible with any standard drill chuck or collet system accepting a 14.00 mm straight-cylindrical shank. Suitable for primary workpiece materials including cast iron, hard materials, non-ferrous metals, stainless steel, and general steel.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with cutting tool setup. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Always power down and lock out the spindle before changing tooling. Do not exceed the recommended maximum drilling depth of 40 mm for this bit length without pecking cycles to clear chips.
