Walter-titex 5059401 Jobber Drill Bit 57 Hss 130 Degree

Product Description

The WALTER-TITEX 5059401 is a jobber-length drill bit sized at wire gauge 57 (0.0430 inches decimal) designed for high-performance drilling in production and maintenance environments. Manufactured from high speed steel with a bright uncoated finish, the bit features a 130-degree standard point angle and a parabolic flute geometry that promotes fast chip evacuation and reduced heat buildup. The straight-cylindrical shank and web-thinned, tapered web construction make this bit well-suited for demanding applications where hole quality and tool life matter. It is a two-flute design built to ANSI and ISO standards and carries a Series A1222 designation.

This drill bit is intended for use in blind hole drilling and stack drilling operations on cast iron, non-ferrous metals, and steel workpieces. The parabolic flute with an 8xD flute-to-diameter ratio supports deeper chip clearance relative to bit diameter, making it appropriate for production shops, job sites, and machine tool environments where consistent hole geometry is required across multiple workpieces. The overall length of 1-7/16 inches suits standard drill chucks used by machinists and maintenance technicians working with small-diameter precision holes.

Key Features

• Wire gauge 57 size at 0.0430 inches decimal diameter with h8 diameter tolerance
• 130-degree standard point angle for effective penetration in ferrous and non-ferrous materials
• Parabolic flute geometry with 8xD flute-by-diameter ratio for efficient chip removal
• Web-thinned, tapered web construction reduces thrust and improves point stability
• Bright uncoated high speed steel construction meets ANSI and ISO standards
• Rated for blind hole and stack drilling tool applications

Compatibility

Designed as an OEM-style replacement and direct-fit jobber drill bit for standard straight-shank drill chucks and collet systems accepting a 0.0430-inch shank diameter. Suitable for use in cast iron, non-ferrous metal, and steel workpiece materials as specified by primary workpiece material codes K, N, and P.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or trained technician using appropriate drill press, CNC, or hand-held power tool equipment rated for the shank diameter. Verify chuck or collet runout before use to maintain hole tolerance at this small diameter. Do not exceed the maximum drilling depth of 0.4720 inches (12.00 mm) per pass without retracting to clear chips. Secure the workpiece properly and follow applicable shop safety procedures for rotating tool operation.
