The SGS 66507 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, web-thinned geometry, and a Ti-NAMITE-X coating that extends tool life in abrasive and hard materials. The 3.40 mm cutting diameter produces an equivalent decimal size of 0.1339 inches. With an overall length of 66.00 mm (2.5984 inches) and a flute length of 28.00 mm (1.1024 inches), this bit suits CNC machining centers, drill presses, and manual operations where tight-tolerance holes are required. It is installed and used by machinists, tool-and-die technicians, and precision fabricators.
The 66507 is suited for precision drilling in ferrous and non-ferrous metals, composites, and other hard materials that benefit from a carbide substrate and advanced coating. The 5xD flute-to-diameter ratio and coolant-through capability make it appropriate for deep-hole applications where chip evacuation and heat management are critical. The straight-cylindrical shank measures 6.00 mm (0.6200 inches) in diameter and 36.00 mm (1.4173 inches) in length, fitting standard collet and drill chuck systems. Maximum drilling depth is 35.00 mm (1.3780 inches).
Designed as an OEM-style replacement and standard jobber drill in the SGS Series 142P lineup, fitting any drill chuck or collet rated for a 6.00 mm straight-cylindrical shank.
Installation is performed by machinists or tool-room technicians. Ensure the spindle and workpiece are fully secured before engaging the drill. Verify coolant-through lines are clear and flowing at the rated pressure for the machine before initiating deep-hole cycles. Do not exceed the maximum drilling depth of 35.00 mm without retracting to clear chips. Replace the bit if runout exceeds tolerance or cutting performance degrades noticeably.
