Walter-titex 5058651 16mm Hss Jobber Drill Bit

Product Description

The WALTER-TITEX 5058651 is a jobber length twist drill bit designed for general-purpose and high-performance hole-making in cast iron and steel. It is manufactured from high speed steel with an oxide coating to reduce friction and extend tool life. The bit measures 16 mm (0.6299 inches) in diameter with an overall length of 178 mm (7-1/64 inches) and a flute length of 120 mm (4-23/32 inches). The standard 118-degree point geometry and web-thinned tip reduce entry force and improve chip evacuation. Two spiral flutes with a regular helix handle chip removal in both blind hole and stack drilling applications. This bit is installed by machinists, maintenance technicians, and trade professionals working in metalworking and fabrication environments.

This drill bit is suited for drilling into cast iron and steel in both blind hole and stack drilling scenarios. The straight-cylindrical shank fits standard drill chucks on drill presses, handheld power drills, and CNC machines. The Series A1211 designation places it within a general-purpose HSS line conforming to ANSI, ISO, BS, and DIN standards. A maximum drilling depth of 104 mm (4.094 inches) and an 8xD flute-to-diameter ratio make it appropriate for through-hole and moderate-depth blind-hole work in production and maintenance settings.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press, handheld, or CNC drilling operations. Secure the workpiece firmly before drilling and ensure the chuck is properly tightened on the shank before operation. Appropriate cutting fluid or lubrication is recommended when drilling steel to manage heat buildup, though this bit does not support coolant-through delivery. Follow applicable workplace safety standards and machine guarding requirements during use.
