The SGS 66640 is a solid carbide taper length drill bit engineered for high-performance drilling in a wide range of materials. Built to DIN 6537 specification, it features a 135-degree split point, web-thinned geometry, and a Ti-NAMITE-X (TX) coating for extended tool life under demanding cutting conditions. The 9/32 inch diameter bit runs with a right-hand spiral flute and supports coolant-through delivery, making it well suited for precision machining operations where heat and chip evacuation are critical. Machinists and toolroom technicians working in metals, composites, and universal-grade materials will find this bit appropriate for CNC and manual drilling setups alike.
The SGS 66640 is designed for universal material applications including steels, alloys, and engineered materials. The 8xD flute-to-diameter ratio provides depth capability beyond standard-length tooling without sacrificing rigidity. Its straight cylindrical shank fits standard drill chucks and collet holders. This bit is a practical choice for production shops, tool rooms, and precision fabrication environments where consistent hole quality and diameter tolerance control are required.
Designed as a high-performance replacement or production drill bit for universal material applications; compatible with standard drill chucks and collet systems accepting a straight cylindrical shank with 8 mm shank diameter.
Installation and use of solid carbide drill bits should be performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and secured before inserting or removing the bit from the chuck or collet. Verify that the holding device matches the 8 mm cylindrical shank diameter to prevent runout or slippage during operation. When using the coolant-through feature, confirm that the machine tool spindle and toolholder are configured for internal coolant supply before engaging coolant flow.
