Walter-titex 5057058 Screw Machine Drill Bit 0.173 in

Product Description

The WALTER-TITEX 5057058 is a screw machine length cobalt vanadium high speed steel drill bit designed for high-performance drilling in demanding trade and industrial applications. Built to Series A1148 standards, it features a 0.173-inch diameter, a 130-degree split point, and a parabolic flute geometry that promotes fast chip evacuation and reduced heat buildup. The straight-cylindrical shank fits standard drill chucks without modification. Web thinning and a tapered web configuration reduce entry force and improve centering accuracy. Licensed machinists, maintenance mechanics, and fabrication professionals commonly use this bit where precision hole sizing and tool longevity are priorities.

This drill bit is suited for drilling cast iron, stainless steel, hard materials, non-ferrous metals, and general steel stock. The screw machine length format - shorter overall length for improved rigidity - makes it a practical choice for CNC machining centers, turret lathes, and production drilling fixtures where chatter and deflection must be minimized. It is equally applicable in manual drill press setups requiring tight hole-diameter tolerances.

Key Features

• 0.173-inch (wire size 17) diameter with a tolerance of -0.00071 to 0.00000 inches for precise hole sizing
• 130-degree split point reduces walking and lowers required thrust force
• Parabolic 2-flute design promotes aggressive chip removal and reduced friction
• Cobalt vanadium HSS construction improves heat and wear resistance over standard HSS
• Web-thinned, tapered web configuration for easier penetration in tough materials
• Bright/uncoated finish; right-hand cut; no coolant-through requirement

Compatibility

Designed as a screw machine length drill bit compatible with primary workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel. Conforms to DIN, ISO, and BS specification designations under Series A1148.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance professionals familiar with rotating cutting tools. Always secure the workpiece and confirm chuck grip before starting the spindle. Verify machine RPM is appropriate for the workpiece material and bit diameter before drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is detected.
