Osg 651042111 Solid Carbide Jobber Drill Bit 27/64 in

Product Description

The OSG 651042111 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding metalworking applications. It features a 27/64 inch (10.72 mm) diameter, a 140-degree R-thinned point for accurate self-centering entry, and an EgiAs coating that extends tool life under elevated cutting temperatures. The straight-cylindrical shank measures 7/16 inch for secure chuck retention. Coolant-through capability makes this bit suitable for deep-hole strategies where chip evacuation and heat management are critical. Licensed machinists, tool-and-die technicians, and production drilling operations are the primary users of this tool.

This bit is built for drilling steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. It is suited to blind hole, cross hole, standard through-hole drilling, and self-centering operations. The 5xD flute-to-diameter ratio and regular spiral geometry support consistent chip flow in both manual and CNC machining centers. The Series 6510 designation places this bit in OSG high-performance tooling for production environments where repeatability and tool life matter.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• EgiAs coating provides thermal and oxidation resistance for extended tool life at higher cutting speeds
• 140-degree R-thinned point reduces entry force and improves self-centering without a center punch
• Coolant-through design supports chip evacuation and heat control in blind and deep-hole drilling
• Tapered web with R-thinned configuration reduces thrust and minimizes chisel-edge wear
• Straight-cylindrical 7/16 inch shank fits standard drill chucks and collet-style toolholders

Compatibility

Designed for use in CNC machining centers and production drilling setups targeting steel, alloy steel, cast iron, titanium, and titanium alloy workpieces. Compatible with standard 7/16 inch straight-shank toolholders and collet chucks.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide drill handling. Power down and lock out the machine spindle before inserting or removing the bit from the toolholder. Carbide tooling is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper feed reduction, or impact-type chuck tightening that could chip the flutes or point. Verify coolant-through passages are clear and coolant pressure is correctly set before running the tool in a blind-hole application.
