Walter-titex 6968801 Screw Machine Drill Bit 8.4mm Carbide

Product Description

The WALTER-TITEX 6968801 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to Series DC150-03-A1, it features an 8.4 mm (0.3307 inch) diameter, a 140-degree split point for accurate self-centering entry, and a TiNAl coating that extends tool life under elevated cutting temperatures. The straight-cylindrical shank measures 10 mm in diameter and 40 mm in length for secure chuck engagement. Overall length is 89 mm (3.504 inches), and maximum drilling depth reaches 35 mm (1.378 inches). This bit ships individually and is suited for machinists, toolroom technicians, and maintenance professionals who need consistent, repeatable hole quality in production environments.

This drill bit is rated for universal tool performance across cast iron, hard materials, non-ferrous metals, and steel. The screw machine length format keeps the tool rigid and reduces deflection in short-reach drilling setups such as drill presses, CNC machining centers, and gang fixtures. Coolant-through capability makes it well suited for high-speed production runs where heat management is critical to maintaining hole tolerance. The 3xD flute-to-diameter ratio provides efficient chip evacuation in deep-hole passes through ferrous and non-ferrous workpieces.

Key Features

• Solid carbide construction for superior rigidity and wear resistance versus high-speed steel alternatives
• TiNAl coating provides thermal protection and extended cutting life in ferrous and hard materials
• 140-degree point angle promotes accurate entry and reduces thrust force on workpiece entry
• Coolant-through design channels cutting fluid directly to the tip for high-speed production drilling
• Straight-cylindrical shank (10 mm diameter) compatible with standard drill chucks and collet systems
• Manufactured to DIN and ISO standards with m7 diameter tolerance for consistent fit and finish

Compatibility

Designed for use in CNC machining centers, drill presses, and similar machine tool setups capable of accepting a 10 mm straight-cylindrical shank. Rated for primary workpiece materials including cast iron, hard material, non-ferrous metal, and steel. Fits drill bit size range 0.3000 to 0.3500 decimal inch (8.00 to 9.50 mm) tooling applications per Series DC150-03-A1 specifications.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom technicians familiar with rotating cutting tools and machine tool safety practices. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the bit from the chuck or collet. Verify shank seating and chuck torque per the machine tool manufacturer guidelines before initiating a cut. Coolant-through setups require confirmation that the machine spindle coolant circuit is compatible with the bit before operation.
