Osg 652012511 Taper Length Drill Bit 1/8 in Carbide

Product Description

The OSG 652012511 is a solid carbide taper length drill bit designed for precision drilling in demanding machining applications. Built with a 140-degree split point and EgiAs coating, this bit reduces walking at entry and resists heat buildup during high-speed cutting. The straight cylindrical shank measures 1/8 inch in diameter, and the spiral flute geometry evacuates chips efficiently in both ferrous and non-ferrous materials. Coolant-through capability supports deep-hole drilling where heat and chip management are critical. At 0.03 pounds, it is lightweight and sized for tight-tolerance work in production and maintenance environments.

This drill bit is suited for metalworking operations where hole accuracy and tool life are priorities. The taper length configuration provides additional flute length compared to a jobber bit, allowing deeper reach without sacrificing rigidity. With a flute-to-diameter ratio of 8xD and X-thinned web geometry, it performs well in CNC machining centers, drill presses, and manual operations requiring controlled feed rates. It is typically installed and operated by machinists, tool-and-die professionals, and precision fabricators working in metal fabrication and maintenance repair.

Key Features

• Solid carbide construction for superior hardness and wear resistance in hard materials
• 140-degree point angle reduces thrust force and minimizes drill walking at entry
• EgiAs coating improves surface lubricity and extends tool life in high-speed applications
• Coolant-through design supports deep-hole drilling with effective chip and heat evacuation
• X-thinned web reduces cutting resistance and improves chisel edge performance
• Right-hand spiral flute for standard clockwise cutting operations

Compatibility

Designed as a taper length replacement drill bit for CNC machining centers and drill presses accepting a 1/8-inch straight cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling procedures. Ensure the spindle and chuck are fully powered down and stopped before changing tooling. Carbide bits are brittle and should not be used with excessive runout or in wobbling chucks, as this can cause chipping or fracture. Confirm coolant-through connections are functional before beginning deep-hole operations.
