Sgs 66514 Solid Carbide Jobber Drill 4.10 Mm 135 Deg

Product Description

The SGS 66514 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to DIN 6537 specification, it features a 135-degree split point with web thinning to reduce thrust and improve hole entry accuracy. The Ti-NAMITE-X coating adds thermal and wear resistance, extending tool life in abrasive and hard materials. With a 4.10 mm cutting diameter, a 74.00 mm overall length (2.9134 inches), and a straight-cylindrical shank, this bit is suited for CNC machining centers, drill presses, and manual setups requiring consistent hole quality. Coolant-through capability supports high-feed-rate operations where chip evacuation and heat management are critical.

The SGS 66514 is intended for precision drilling in ferrous and non-ferrous metals, hardened steels, stainless alloys, and similar materials where carbide tooling is specified. Its 5xD flute-to-diameter ratio and two-flute spiral design facilitate efficient chip removal in deep-hole applications up to 43.00 mm (1.6929 inches). This drill is a practical choice for machine shops, tool rooms, aerospace fabrication, and other environments that require tight-tolerance hole-making with consistent repeatability across production runs.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• Ti-NAMITE-X coating provides thermal protection and extends cutting life
• 135-degree standard point with web thinning reduces entry thrust and improves centering
• Coolant-through design supports chip evacuation in deep-hole drilling
• Straight-cylindrical shank with 6.00 mm diameter fits standard drill chucks and collets
• Built to DIN 6537 specification for consistent dimensional tolerances

Compatibility

Designed as an OEM-style replacement and standard production drill for use in CNC machining centers, drill presses, and manual spindles accepting a 6.00 mm straight-cylindrical shank. Fits applications within the 4.00 mm to 5.00 mm drill diameter range per Series 142P sizing.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine in a full stop and de-energized state. Confirm chuck or collet runout is within acceptable limits before seating the shank to avoid premature cutting edge wear. When using the coolant-through feature, verify coolant pressure and flow rate are appropriate for the machine spindle before initiating a cut. Follow the machine manufacturer and applicable workplace safety guidelines for carbide tooling handling, as carbide edges are brittle and can chip if dropped or impacted.
