Walter-titex 6968827 Screw Machine Drill Bit 10.50mm

Product Description

The WALTER-TITEX 6968827 is a screw machine length solid carbide drill bit designed for high-performance drilling in demanding machining applications. Built to Series DC150-03-A1 specifications, this bit features a 140-degree point angle for self-centering entry and reduced thrust, and a TiNAl (titanium aluminum nitride) coating that extends tool life in abrasive and high-heat cutting environments. At 10.50 mm in diameter with a 4.016-inch overall length, it is sized for production drilling work where compact length and rigidity matter. Coolant-through construction allows cutting fluid to reach the tip directly, improving chip evacuation and thermal management. Machinists and tool-and-die professionals working on CNC machining centers and drill presses will find this bit suited to tight-tolerance hole work.

This drill bit is used in screw machine and general production drilling operations where solid carbide rigidity outperforms high-speed steel in harder workpiece materials. The 3xD flute-by-diameter ratio and 55 mm flute length support drilling to a maximum depth of 40.00 mm (1.575 inches). Its right-hand cutting direction is standard for conventional spindle rotation. Applications include metalworking shops, toolrooms, and production machining environments where consistent hole geometry and tool life are priorities.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard material drilling
• 140-degree point angle reduces entry thrust and improves self-centering
• TiNAl coating extends tool life in high-temperature and abrasive cutting conditions
• Coolant-through design delivers fluid directly to the cutting zone for improved chip evacuation
• 3xD flute ratio supports drilling to 40.00 mm maximum depth
• Screw machine length (short) body improves rigidity and reduces deflection

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide drill bit for use in standard drill chucks and collet systems accepting a 12.00 mm shank diameter, within the 9.50 to 11.00 mm drill bit size range (0.4000 to 0.4500 decimal inch).

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists familiar with CNC or manual drill press operation. Ensure the machine spindle is fully stopped and power is locked out before inserting or removing the bit from the chuck or collet. Confirm the shank diameter matches the holding device before securing; improper fitment can cause runout and premature tool failure. Coolant-through systems should be verified for pressure compatibility before use at full depth.
