Sgs 66605 Solid Carbide Jobber Drill Bit 16mm 135 Deg

Product Description

The SGS 66605 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding production environments. Built to DIN 6537 specification, it features a 16.00 mm (0.6299 inch) diameter, a 135-degree split point for accurate self-centering starts, and SGS Ti-NAMITE-X (TX) proprietary coating for extended tool life. The two-flute right-hand spiral design combined with web thinning reduces cutting forces and improves chip evacuation. Coolant-through capability makes this bit well-suited for deep-hole applications where heat management is critical. Machinists, tooling specialists, and CNC operators working in metals and hard materials are the primary users of this tool.

The SGS 66605 Series 142P drill is intended for use in CNC machining centers, drill presses, and production drilling operations where tight tolerances and surface integrity are required. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 63.00 mm (2.4803 inches), it handles moderate-depth bores effectively. The straight cylindrical shank with a 16.00 mm shank diameter seats securely in standard ER or hydraulic chuck toolholders. This bit is well-matched for applications in aerospace, automotive, die-mold, and general precision machining where micrograin carbide substrate and high-performance coatings are specified.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance in hard materials
• Ti-NAMITE-X (TX) proprietary coating reduces friction and extends tool life
• 135-degree standard point angle with web thinning for reduced thrust and accurate entry
• Coolant-through design supports deep-hole drilling and effective heat removal
• Right-hand cut, regular spiral flute geometry promotes consistent chip evacuation
• Manufactured to DIN 6537 specification for dimensional consistency and interchangeability

Compatibility

Designed as a high-performance OEM-style replacement or upgrade drill bit for CNC and production drilling setups requiring a 16.00 mm straight-shank carbide jobber drill conforming to DIN 6537. Compatible with standard straight-bore ER collet chucks, hydraulic chucks, and Weldon-style holders accepting a 16.00 mm cylindrical shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per applicable safety procedures. Ensure the shank seating surface and chuck bore are clean and free of chips before securing the bit. Do not exceed the recommended maximum drilling depth of 63.00 mm without retracting to clear chips, particularly in blind-hole applications. Consult the machine tool manufacturer and SGS cutting data recommendations for appropriate feed rate and spindle speed for the specific workpiece material.
