Walter-titex 7462162 Carbide Drill Bit 7/16 Inch Tinal

Product Description

The WALTER-TITEX 7462162 is a jobber length drill bit engineered for demanding metal drilling applications in professional machining and fabrication environments. Built from solid carbide with a TiNAl (titanium aluminum nitride) coating, it delivers high wear resistance and thermal stability under aggressive cutting conditions. The 140-degree split point promotes accurate entry and reduces walking on hard surfaces. With a 7/16 inch (0.4375 inch) diameter, spiral flute geometry, and right-hand cut direction, this bit is designed for consistent chip evacuation and repeatable hole quality in production and maintenance settings.

This drill bit is suited for blind hole drilling and stack drilling operations in cast iron and steel workpieces. It belongs to WALTER-TITEX Series DC150, a line targeted at industrial cutting tool applications where dimensional accuracy and tool life are priorities. It is typically used in CNC machining centers, drill presses, and hand-held power tools by machinists, tool-and-die professionals, and maintenance technicians working with ferrous metals. The straight-cylindrical shank fits standard drill chucks without adapters.

Key Features

• Solid carbide construction with TiNAl coating for extended tool life in ferrous materials
• 140-degree drill point angle reduces thrust and improves entry accuracy
• Spiral flute design promotes efficient chip evacuation during blind hole and stack drilling
• Right-hand cut direction; compatible with standard CNC and manual drill setups
• Straight-cylindrical shank with 12 mm shank diameter for secure chuck retention
• 5xD flute-to-diameter ratio supports drilling depths up to 56 mm

Compatibility

Designed for drilling cast iron and steel workpieces. Primary workpiece material codes K and P per ISO classification. Conforms to ANSI and ISO standards. Suitable for blind hole and stack drilling applications within the 0.4000 to 0.5000 inch drill bit size range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with cutting tool safety practices. Ensure the spindle and workpiece are fully secured before initiating a cut. This bit does not support coolant-through delivery; use appropriate external coolant or cutting fluid for the workpiece material to manage heat buildup. Inspect the cutting edges for wear or chipping before each use and replace when dimensional tolerance or surface finish degrades.
