Osg 651012511 Jobber Drill Bit 1/8 Inch Solid Carbide

Product Description

The OSG 651012511 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding metalworking applications. It measures 1/8 inch (3.18 mm) in diameter with a 140-degree point angle and an overall length of 86 mm (approximately 3.39 inches). The bit carries an EgiAs coating to extend tool life and reduce heat buildup at the cutting edge. It features a right-hand spiral flute with a straight-cylindrical shank and an R-thinned web for improved chip evacuation and self-centering performance. Machinists and tool-and-die professionals use this bit in production environments where tool consistency and material hardness demand carbide over high-speed steel.

This drill bit is rated for use in steel, alloy steel, cast iron, titanium, and titanium alloys, covering ISO material codes P, K, S, and H. It supports blind hole drilling, cross hole drilling, general drilling, and self-centering operations. The 5xD flute-to-diameter ratio and coolant-through capability make it well suited for CNC machining centers and automated production lines where through-coolant is available. It is packaged and sold individually.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EgiAs coating reduces friction and extends tool life in ferrous and exotic alloy applications
• 140-degree R-thinned point improves self-centering and reduces thrust force at entry
• Coolant-through design supports high-speed production drilling with through-coolant systems
• Right-hand spiral flute with regular spiral type for consistent chip evacuation
• Straight-cylindrical shank for use in standard drill chucks and collet holders

Compatibility

Designed for use in steel, alloy steel, cast iron, titanium, and titanium alloys (ISO material codes P, K, S, H). Suitable for blind hole, cross hole, and general drilling operations. Compatible with any machine tool setup accepting a 1/8-inch straight-cylindrical shank.

Installation Notes

This bit is installed by machinists or CNC operators in drill chucks or collet holders rated for 1/8-inch shanks. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. When using coolant-through capability, verify that coolant pressure and flow rate are within the machine tool manufacturer's specifications. Avoid side-loading or using this bit as a reamer, as carbide is brittle under lateral stress.
