Sgs 66672 Taper Length Drill Bit 15/64 in Solid Carbide

Product Description

The SGS 66672 is a taper length drill bit designed for demanding drilling applications where precision and tool life are critical. Built from micrograin solid carbide with a TX coating, this bit delivers hardness and wear resistance across a wide range of workpiece materials. It measures 15/64 inch (0.3780 inch decimal) in diameter with a 135-degree split point and a spiral flute configuration. The overall length is 141.99 mm and the flute length is 95.00 mm, providing an 8xD flute-to-diameter ratio suited for deeper hole applications. Coolant-through capability supports chip evacuation during high-feed operations. This bit is intended for installation by machinists, tool-and-die tradespeople, and maintenance professionals working with precision drilling equipment.

The SGS 66672 is rated for universal material application, making it appropriate for ferrous metals, non-ferrous alloys, and similar materials encountered in production and maintenance environments. The right-hand cut spiral flute and web-thinned point reduce entry thrust and improve chip flow. The cylindrical shank measures 10.00 mm in diameter with a shank length of 40.00 mm (1-13/32 inch), fitting standard drill chucks and collet holders compatible with that shank size. This bit conforms to DIN 6537 specification and is classified as a high-performance grade, suitable for CNC machining centers and manual drill presses where consistent hole geometry is required.

Key Features

• Micrograin solid carbide construction for extended tool life and heat resistance
• TX coating reduces friction and improves wear resistance across universal material applications
• 135-degree split point with web thinning minimizes entry thrust and improves centering
• Coolant-through design supports chip evacuation in deep-hole and high-feed operations
• 8xD flute-to-diameter ratio provides 3.74 inch maximum drilling depth
• Conforms to DIN 6537 specification for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement and direct-fit taper length drill bit for standard drill chucks and collet systems accepting a 10.00 mm cylindrical shank, conforming to DIN 6537 specification.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance tradespeople familiar with rotary cutting tool procedures. Ensure the machine spindle is fully powered down and locked out before changing tooling. Verify that the chuck or collet holder is rated for the 10.00 mm cylindrical shank and that runout is within acceptable tolerances before beginning a drilling operation. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature tool wear or breakage.
