Sgs 66665 Taper Length Drill Bit 8.9mm Solid Carbide

Product Description

The SGS 66665 is a taper length drill bit engineered for high-performance drilling in a wide range of materials. Built from micrograin solid carbide and coated with Ti-NAMITE-X (TX) for extended wear resistance, this bit delivers consistent cutting performance in demanding shop and field environments. It features a 135-degree split point for accurate self-centering and reduced thrust on entry. The 8xD flute-to-diameter ratio and web-thinned geometry promote efficient chip evacuation through the 95 mm spiral flute. Coolant-through capability makes it well suited for deep-hole applications where heat management is critical. Machinists and tool-and-die professionals working with CNC equipment or manual drill presses are the primary users.

This bit is designed for universal material applications including steel, stainless steel, cast iron, aluminum, and non-ferrous metals. The Series 142P taper length format positions it for jobs requiring greater reach than a jobber-length bit without sacrificing rigidity. With a right-hand spiral flute and straight cylindrical shank, it seats directly in standard drill chucks and collet holders. It conforms to DIN 6537 specifications, making it a standard reference for shops that specify tooling by DIN designation. Typical install scenarios include production drilling, tool room work, and precision hole-making in fabrication environments.

Key Features

• Micrograin solid carbide construction for rigidity and long tool life
• Ti-NAMITE-X (TX) coating reduces friction and extends cutting edge life
• 135-degree split point with web thinning for self-centering and reduced entry thrust
• Coolant-through design supports deep-hole drilling and heat management
• Right-hand cut with regular spiral flute for efficient chip removal
• Conforms to DIN 6537 specification for standardized tooling reference

Compatibility

Designed as an OEM-style replacement and standard tooling option for applications specifying Series 142P taper length carbide drill bits per DIN 6537. Compatible with standard drill chucks and collet holders accepting a straight cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists familiar with speeds and feeds for solid carbide tooling. Ensure the machine spindle and chuck are fully powered down and locked out before loading or removing the bit. Verify shank seating and runout before beginning a cut, as excessive runout can chip carbide tooling. Coolant-through setups should be confirmed for proper flow before engaging deep-hole drilling cycles.
