Sgs 66627 Taper Length Drill Bit 1/8 in Solid Carbide

Product Description

The SGS 66627 is a taper length drill bit engineered for high-performance drilling in demanding applications. Built from micrograin solid carbide and finished with a TX coating, it delivers consistent cutting performance in a wide range of work materials. The 135-degree split point reduces walking at entry and minimizes the need for a center punch. With a 1-21/64 inch flute length and 2-53/64 inch overall length, this bit fits standard drill chucks and CNC machining centers. The web-thinned geometry lowers thrust requirements and improves chip evacuation. Coolant-through capability supports high-speed production environments. This is a precision ground tool intended for machinists, toolroom techs, and production drilling applications.

The SGS 66627 is suited for universal material applications including ferrous and non-ferrous metals, alloys, and engineered materials. The cylindrical shank and 8xD flute-to-diameter ratio make it appropriate for both manual drill press setups and CNC operations requiring consistent hole depth and diameter tolerance. The DIN 6537 specification confirms dimensional conformance to international tooling standards. It is typically selected for precision drilling tasks where hole quality, tool life, and dimensional accuracy are priorities.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• TX coating reduces friction and improves wear resistance at the cutting edge
• 135-degree web-thinned point minimizes entry walking and reduces thrust load
• Coolant-through design supports high-speed and deep-hole drilling cycles
• Right-hand spiral flute with cylindrical shank for standard chuck and collet compatibility
• Conforms to DIN 6537 specification for dimensional consistency

Compatibility

Designed as a universal-material taper length drill bit with a cylindrical shank conforming to DIN 6537. Compatible with standard drill chucks, ER collets, and CNC tool holders sized for a 5.99 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Secure the cylindrical shank fully in the chuck or collet before operation, and confirm runout is within acceptable limits for the application. Carbide tooling is brittle — avoid lateral loading, interrupted cuts without proper setup, or improper feed rates that can cause chipping or fracture. When using coolant-through capability, verify that the machine spindle and tool holder support through-coolant flow before use.
