Sgs 66638 Taper Length Drill Bit 6.2mm Solid Carbide

Product Description

The SGS 66638 is a taper length drill bit from the Series 142P line, engineered for high-performance drilling in a wide range of materials. Built from micrograin solid carbide and coated with Ti-NAMITE-X (TX) for extended wear resistance, this bit handles demanding applications where standard high-speed steel tooling falls short. The 135-degree split point reduces walking and thrust, while the web-thinned tip improves chip evacuation from the start of the cut. With an 8xD flute-to-diameter ratio and coolant-through capability, it is well suited for deep-hole drilling in production environments. The cylindrical straight shank mounts in standard drill chucks or collet holders without modification.

This drill bit is designed for use in CNC machining centers, drill presses, and manual machines where tight diameter tolerances and clean exit holes are required. The universal material application rating makes it appropriate for steel, stainless steel, cast iron, aluminum, and similar workpiece materials. Machinists, tool-and-die makers, and maintenance technicians working in metal fabrication, job shops, and industrial maintenance will find this bit applicable to a broad range of production and repair drilling tasks.

Key Features

• Micrograin solid carbide construction for high hardness and heat resistance
• Ti-NAMITE-X coating provides enhanced lubricity and extended tool life
• 135-degree standard point angle with web thinning reduces entry force and improves centering
• Coolant-through design supports internal coolant delivery for deep-hole applications
• Right-hand spiral flute geometry promotes efficient chip removal
• Meets DIN 6537 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement and standard taper length drill bit compatible with CNC and manual drilling setups that accept a straight cylindrical shank at the specified 6.2 mm diameter.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the collet or chuck and verify runout before beginning a cut. When using the coolant-through feature, confirm that coolant pressure and flow rate are appropriate for the machine and workpiece material before engaging the spindle.
