Sgs 66575 Solid Carbide Jobber Drill 10.20mm 135 Deg

Product Description

The SGS 66575 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and non-ferrous materials. It features a 10.20 mm (0.4016 inch) diameter and a 135-degree split point for reduced thrust and self-centering on entry. The Ti-NAMITE-X coating provides enhanced wear resistance and heat dissipation, extending tool life in demanding production environments. With a micrograin carbide substrate and web-thinned geometry, this drill is built for machinists and toolroom professionals running CNC and manual drilling operations where dimensional accuracy and tool longevity are priorities.

This drill bit is suited for precision hole-making in production and job-shop environments. The straight-cylindrical shank fits standard drill chucks and collet holders across CNC machining centers, drill presses, and manual machines. The coolant-through design supports internal coolant delivery, making it effective for deeper hole applications and higher feed rates. It is manufactured to DIN 6537 specification and falls within the Series 142P product family, targeting applications that demand tight tolerances and consistent performance across repeated cycles.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in demanding cut conditions
• Ti-NAMITE-X coating reduces friction and extends tool life in high-cycle drilling applications
• 135-degree split point minimizes walking and reduces entry thrust without a center punch
• Coolant-through capability supports internal flood coolant for deeper holes and higher feed rates
• Web-thinned geometry lowers cutting forces and improves chip evacuation through the spiral flutes
• Manufactured to DIN 6537 specification for consistent geometry and dimensional tolerances

Compatibility

Designed as a high-performance replacement for standard jobber drill bits in the 10.00 mm to 12.50 mm diameter range. Fits any drill chuck or collet system that accepts a 12.00 mm straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within acceptable limits before seating the shank, as excessive runout will reduce tool life and hole quality. Do not exceed the maximum drilling depth of 49.00 mm without retracting to clear chips.
