Walter-titex 5060434 Jobber Drill Bit 8.7mm Hss

Product Description

The WALTER-TITEX 5060434 is a jobber length drill bit engineered for high-performance drilling in demanding materials. Built from vanadium high speed steel with a bright uncoated finish, it measures 8.7 mm (0.3425 inches) in diameter with an overall length of 125 mm (4.92 inches) and a flute length of 81 mm (3.19 inches). The 130-degree drill point angle and web-thinned, tapered web geometry reduce entry thrust and improve centering in hard materials. A spiral flute with a right-hand cut provides efficient chip evacuation. This bit is suited for trade machinists, tool-and-die shops, and maintenance technicians working with hard ferrous stock.

The 5060434 is designed for blind hole drilling and stack drilling applications in stainless steel, superalloys, and titanium. Its 8xD flute-to-diameter ratio and straight-cylindrical shank make it compatible with standard drill chucks and collet holders used in both manual and CNC setups. The Series A1244 designation places it within a consistent line of precision jobber bits built to ANSI, ISO, BS, and DIN specifications. Typical use cases include fabrication shops, aerospace MRO, and industrial maintenance where material hardness demands a purpose-built HSS bit.

Key Features

• Vanadium high speed steel construction for durability in hard and abrasive workpiece materials
• 130-degree point angle optimized for stainless steel, superalloys, and titanium
• Web-thinned tapered web reduces thrust load and improves drill entry accuracy
• Bright uncoated finish maintains close dimensional tolerances to h8 standard
• Right-hand spiral flute with regular helix provides consistent chip clearance
• Meets ANSI, ISO, BS, and DIN standards for interchangeability and dimensional consistency

Compatibility

Designed for use in standard drill chucks and collet systems accepting an 8.7 mm (0.3430-inch) straight-cylindrical shank. Rated for drilling stainless steel, superalloys, and titanium. Suited for blind hole and stack drilling operations per Series A1244 design parameters.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with metalworking equipment. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Do not exceed the recommended maximum drilling depth of 66 mm (2.598 inches) without retracting to clear chips. Coolant-through is not supported on this bit; use external cutting fluid appropriate for the workpiece material when drilling stainless steel or superalloys.
