Sgs 66668 Taper Length Drill Bit 9.2mm Solid Carbide

Product Description

The SGS 66668 is a taper length drill bit in the Series 142P line, manufactured from micrograin solid carbide and coated with Ti-NAMITE-X (TX) for extended tool life in demanding applications. The bit features a 135-degree split point for accurate starts and reduced walking on entry, an 8xD flute-to-diameter ratio that provides chip evacuation depth, and a web-thinned geometry that lowers thrust force. Coolant-through capability is built into the shank, supporting high-speed drilling in production environments. Installed by machinists and tool-room technicians, this bit is suited for CNC machining centers and drill presses requiring a precise, long-reach hole in a 9.2 mm diameter.

The SGS 66668 carries a universal material application rating, meaning it is engineered to cut a broad range of workpiece materials including steels, stainless steels, cast iron, and non-ferrous alloys. The 8xD flute length supports deep-hole drilling cycles without the need for a separate extended-reach tool. The straight cylindrical shank fits standard drill chucks and collet holders. Conforming to DIN 6537, this bit meets a recognized international specification for twist drills, giving shops a consistent benchmark for tool qualification and replacement cycles.

Key Features

• Micrograin solid carbide substrate for rigidity and wear resistance in high-performance applications
• Ti-NAMITE-X coating reduces friction and extends cutting edge life across universal material grades
• 135-degree standard point with web thinning for accurate entry and reduced axial thrust
• Coolant-through design supports internal coolant delivery for deep-hole operations
• 8xD flute-to-diameter ratio allows deep drilling without tool change to an extended-reach variant
• Conforms to DIN 6537 specification for consistent replacement and qualification standards

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers, drill presses, and multi-spindle machines accepting a straight cylindrical shank drill bit in 9.2 mm diameter. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation is performed by machinists or tool-room personnel following standard tooling change procedures. Secure the cylindrical shank firmly in a properly sized collet or drill chuck before beginning any cutting cycle. Verify that coolant-through supply lines are connected and at the correct flow rate before engaging internal coolant during drilling. Inspect the cutting edges for chipping or wear before each use, as carbide tooling can sustain micro-damage that is not visible to the unaided eye at normal lighting.
