Walter-titex 5058597 12mm Hss Jobber Drill Bit

Product Description

The WALTER-TITEX 5058597 is a jobber length drill bit designed for general-purpose drilling in cast iron and steel. Built from high speed steel with an oxide coating, it measures 12 mm (0.4724 inches) in diameter and carries an overall length of 151 mm (5-15/16 inches). The standard 118-degree split point with web thinning reduces entry force and improves centering accuracy. Two spiral flutes with a regular helix evacuate chips efficiently during through-hole and blind-hole operations. This bit is sized within the Series A1211 family and meets ANSI, ISO, BS, and DIN standards. It is installed by machinists, maintenance technicians, and mechanical contractors using standard drill presses, CNC machines, or hand-held power drills.

This drill bit is suited for blind hole drilling and stack drilling applications in cast iron and steel workpieces. The straight-cylindrical shank fits standard drill chucks without adapters. The 8xD flute-to-diameter ratio and a maximum drilling depth of 87 mm (3.4250 inches) make it practical for moderate-depth holes in production and maintenance environments. The h8 diameter tolerance supports consistent fit in precision fixtures. Right-hand cut geometry is compatible with standard forward-rotation spindles found across most drilling equipment.

Key Features

Compatibility

Designed as an OEM-style jobber length drill bit for use in standard drill chucks and collet holders accepting a 0.4724-inch straight-cylindrical shank across drill presses, machining centers, and hand-held power drills.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Power down and lock out all equipment before changing bits. Apply cutting fluid appropriate for the workpiece material to extend tool life and maintain bore quality. Follow applicable ANSI B11 machine safety standards when operating drilling equipment.
