Walter-titex 5057086 Screw Machine Drill Bit 0.0935in

Product Description

The WALTER-TITEX 5057086 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit measures 0.0935 inches in diameter and features a parabolic flute geometry with a web-thinned, tapered web configuration. The 130-degree split point reduces walking and improves chip evacuation. At 1-11/16 inches overall length with a maximum drilling depth of 0.400 inches, it fits short-reach drilling setups where stub or screw machine length tooling is required. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the primary users.

This drill bit is suited for production and maintenance drilling in cast iron, stainless steel, hardened steel, non-ferrous metals, and other hard materials. The Series A1148 designation indicates a universal-performance tool built to DIN, ISO, and BS standards. It is appropriate for use in CNC machining centers, drill presses, and manual lathes where a straight cylindrical shank and tight diameter tolerance are required. The 3xD flute-to-diameter ratio supports chip clearance in shallow-to-moderate depth holes. Right-hand cut only.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat and wear resistance in hard materials
• 130-degree split point reduces thrust and prevents bit walking on entry
• Parabolic flute profile improves chip evacuation and reduces recutting
• Web-thinned tapered web lowers cutting forces at the tip
• Tight diameter tolerance of -0.00055 to 0.00000 inches ensures hole accuracy
• Meets DIN, ISO, and BS standards for dimensional and performance consistency

Compatibility

Designed as a screw machine length replacement drill bit for applications requiring a 0.0935 inch (Wire Size 42) straight shank bit compatible with standard drill chucks and collet systems accepting a straight cylindrical shank in this diameter range.

Installation Notes

This bit is installed by machinists and metalworking technicians in drill presses, CNC machining centers, or manual lathes. Secure the straight cylindrical shank fully in the chuck or collet before operation and verify runout before drilling. Power down and lock out the machine before changing tooling. Do not use coolant-through setups with this bit as it is not rated for coolant-through delivery.
