Walter-titex 6968773 Carbide Screw Machine Drill Bit 6.2mm

Product Description

The WALTER-TITEX 6968773 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding production environments. It features a 6.2 mm diameter cutting edge with a 140-degree split point and a TiNAl (titanium aluminum nitride) coating for extended tool life and heat resistance. The bit runs a right-hand cut, uses a straight-cylindrical shank measuring 8 mm in diameter, and delivers coolant-through capability for chip evacuation and thermal management during deep drilling operations. Machinists and tool-room professionals install this bit in CNC machining centers and drill presses where close-tolerance, high-cycle work is required.

This drill bit is rated for use in cast iron, hard materials, non-ferrous metals, and steel, covering a broad range of production machining scenarios. Its screw machine (stub) length geometry provides rigidity over long run cycles, reducing deflection in applications where hole position and diameter tolerance are critical. The DC150-03-A1 series is designed for universal tool performance across a 5.00 to 6.50 mm diameter range classification, making it a standard-fit selection for shops working within that size band.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-cycle machining
• TiNAl coating improves heat resistance and extends cutting edge life
• 140-degree point angle reduces thrust force and improves chip formation
• Coolant-through design supports chip evacuation and temperature control during drilling
• Straight-cylindrical shank for reliable clamping in standard drill chucks and collets
• Right-hand cut, 2-flute configuration; flute-to-diameter ratio of 3xD for screw machine length stability

Compatibility

Designed for use in CNC machining centers and drill presses compatible with straight-cylindrical shank tooling; suitable for primary workpiece materials including cast iron, hard materials, non-ferrous metals, and steel. Conforms to DIN and ISO standards.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank diameter compatibility with the holder and apply appropriate clamping torque per the machine manufacturer specification. Coolant-through capability requires a compatible spindle or toolholder with internal coolant supply to be effective.
