Walter-titex 7462125 Solid Carbide Jobber Drill Bit 8 Mm

Product Description

The WALTER-TITEX 7462125 is a solid carbide jobber-length drill bit designed for precision hole-making in ferrous materials. Built to Series DC150 standards, it carries a TiNAl coating that extends tool life in abrasive cutting conditions. The 8 mm diameter bit features a 140-degree drill point angle optimized for self-centering entry and clean breakthrough on cast iron and steel workpieces. With a two-flute spiral design and a straight-cylindrical shank, it fits standard drill chucks without adapters. Right-hand cut geometry and an overall length of 91 mm make it a reliable choice for production-floor and maintenance drilling operations.

This drill bit is rated for use in cast iron and steel applications, covering material grades within the K and P workpiece material codes. It is well-suited for blind hole drilling and stack drilling scenarios in both light manufacturing and heavy fabrication environments. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes, with a maximum drilling depth of 43 mm. Machinists, tool-and-die technicians, and maintenance mechanics working in production shops will find this bit at home in CNC drilling centers, radial arm drills, and manual drill presses alike.

Key Features

• Solid carbide construction with TiNAl coating for extended wear resistance in ferrous materials
• 140-degree split-point geometry promotes self-centering and reduces thrust force on entry
• Two-flute spiral design supports efficient chip evacuation in blind hole and stack drilling
• Straight-cylindrical shank at 8 mm diameter fits standard drill chucks directly
• 5xD flute ratio with 43 mm maximum drilling depth suits typical through and blind hole work
• Meets ANSI and ISO standards; material grade WJ30TA for consistent carbide performance

Compatibility

Designed for drilling cast iron and steel workpieces; compatible with standard 8 mm straight-shank drill chucks on CNC machining centers, drill presses, and hand-held power drills with sufficient torque capacity.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with carbide drill bit handling. Secure the shank fully within the chuck jaws before operation and verify runout is within acceptable tolerance to avoid premature chipping of the carbide flute edges. This bit does not support coolant-through delivery; external flood or mist coolant is recommended when drilling steel at elevated feed rates. Inspect the cutting edges for chipping or wear before each use, as carbide is brittle and sensitive to impact loading from interrupted cuts.
