Walter-titex 7462141 Carbide Jobber Drill Bit 9.3 Mm

Product Description

The WALTER-TITEX 7462141 is a solid carbide jobber length drill bit designed for precise, high-performance drilling in ferrous materials. It measures 9.3 mm in diameter with a 140-degree drill point angle and features a TiNAl (titanium aluminum nitride) coating that extends tool life under elevated cutting temperatures. The overall length is 103 mm, with a flute length of 61 mm and a maximum drilling depth of 49 mm. The straight-cylindrical shank measures 10 mm in diameter. With a right-hand spiral flute configuration and a 5xD flute-to-diameter ratio, this bit is suited for demanding production drilling operations. It carries a material grade designation of WJ30TA and meets ANSI and ISO standards.

This drill bit is intended for use in cast iron and steel workpieces, covering primary material codes K and P. It is well-suited for blind hole drilling and stack drilling applications in industrial and manufacturing environments. Typical users include machinists, tool and die specialists, and CNC operators working in production shops or maintenance operations. The DC150 series designation places this bit within a professional-grade carbide drill line built for consistent tolerance and repeatable performance across multi-piece runs.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard ferrous materials
• TiNAl coating improves heat resistance and extends cutting life
• 140-degree drill point angle reduces thrust and minimizes workpiece deformation on entry
• Right-hand spiral flute with 5xD ratio promotes efficient chip evacuation
• Straight-cylindrical 10 mm shank for compatibility with standard chuck and collet toolholding
• Rated for blind hole and stack drilling applications
• Meets ANSI and ISO dimensional standards; diameter tolerance class m7

Compatibility

Designed for use in cast iron and steel workpieces (material codes K and P). Compatible with standard straight-shank toolholding systems that accept a 10 mm shank diameter. Part of the WALTER-TITEX DC150 series.

Installation Notes

This drill bit is installed and operated by machinists or CNC technicians using compatible drill chucks, collet holders, or hydraulic toolholders rated for the 10 mm shank diameter. Always ensure the machine spindle is fully stopped and the workpiece is properly clamped before tool changes. Carbide tooling is brittle — avoid lateral loading or interrupted cuts that could cause chipping or fracture. Verify spindle speed and feed rate settings match the workpiece material and bit diameter before beginning a drilling cycle.
