Walter-titex 6968709 Screw Machine Drill Bit 3mm Carbide

Product Description

The WALTER-TITEX 6968709 is a screw machine length solid carbide drill bit designed for high-performance drilling in metalworking applications. It features a 3 mm (0.1181 inch) diameter, a 140-degree split point, and a TiNAl (titanium aluminum nitride) coating that extends tool life in demanding materials. The bit measures 62 mm (2.441 inches) overall length with a 6 mm (0.236 inch) straight-cylindrical shank. Coolant-through design supports internal coolant delivery, making it well suited for CNC machining centers and automated drilling operations. This bit is sold individually and is part of the DC150-03-A1 series.

This drill bit is engineered for production and job shop environments where consistent hole quality across high-volume runs is required. Its screw machine length profile provides rigidity in short-reach applications. The universal tool performance rating and flute-by-diameter ratio of 3xD make it appropriate for cast iron, hardened materials, non-ferrous metals, and steel workpieces. It is a standard choice for machinists and tool-and-die professionals running drilling operations on vertical machining centers, drill presses, and multi-axis CNC equipment.

Key Features

• Solid carbide construction for rigidity and wear resistance in metal drilling
• TiNAl coating improves heat resistance and extends tool life in steel and hard materials
• 140-degree point angle reduces thrust force and improves self-centering on entry
• Coolant-through design supports internal coolant delivery for chip evacuation and heat control
• Straight-cylindrical shank compatible with standard ER collets and drill chucks
• Meets DIN and ISO dimensional standards for consistent toolholder fit

Compatibility

Designed as an OEM-style replacement drill bit for use in standard straight-shank toolholders and ER collet chucks accepting a 6 mm shank diameter. Suitable for primary workpiece materials including cast iron, hard material, non-ferrous metal, and steel per series DC150-03-A1 application guidelines.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Seat the shank fully in the collet or chuck and verify runout before beginning a drilling cycle. When using the coolant-through feature, confirm that coolant pressure and flow rate are set per the machine tool manufacturer specifications. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge condition is degraded.
