Sgs 66699 Taper Length Drill Bit 13mm Solid Carbide

Product Description

The SGS 66699 is a taper length drill bit engineered for high-performance metal cutting and universal material applications. Built from micrograin solid carbide with a TX coating, this bit delivers extended tool life and thermal resistance in demanding drilling operations. It features a 135-degree split point for accurate self-centering entry and reduced thrust, a right-hand spiral flute for efficient chip evacuation, and a web-thinned geometry that lowers cutting resistance. The cylindrical shank measures 14 mm in diameter, and the overall length is 178 mm. Coolant-through capability makes it well-suited for deep-hole work where heat and chip buildup are concerns.

The SGS 66699 is designed for use in CNC machining centers, drill presses, and production environments where consistent hole quality is required across a range of materials including steel, stainless, cast iron, and non-ferrous alloys. The Series 142P geometry with an 8xD flute-to-diameter ratio supports taper-length drilling in applications that exceed the reach of jobber-length tooling. It is a common choice for tool and die, aerospace component, and general metalworking shops.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TX coating for improved surface hardness and heat resistance
• 135-degree standard point with web thinning for reduced entry thrust
• Coolant-through design supports deep-hole drilling and extended tool life
• Right-hand spiral flute for positive chip evacuation
• DIN 6537 specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement and standard production drill bit compatible with CNC machining centers and drill presses that accept a 14 mm cylindrical shank. Suitable for universal material applications per Series 142P specifications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out. Ensure the tool holder or chuck is rated for the 14 mm cylindrical shank diameter before clamping. When activating coolant-through capability, verify that the machine spindle and toolholder support internal coolant delivery at the required pressure. Inspect the cutting edge for chips or wear before each use and replace if edge integrity is compromised.
