Osg 8670240 Screw Machine Drill Bit 0.0945 in Carbide

Product Description

The OSG 8670240 is a screw machine length solid carbide drill bit designed for high-performance drilling in ferrous and hard materials. With a 0.0945 inch (2.40 mm) diameter, a 140-degree split point, and an X-thinned web, it reduces thrust on entry and maintains accurate hole placement. The straight-cylindrical shank measures 0.1575 inches in diameter, and the overall length is 2.44 inches (62.00 mm). The spiral flute geometry and tapered web configuration promote efficient chip evacuation. This bit is built for production drilling environments and is typically operated by machinists, tool-and-die workers, and metal fabrication professionals.

The 8670240 is suited for screw machine applications and short-hole drilling in ferrous metals. Primary workpiece materials include steel, alloy steel, and cast iron. The 2xD flute-to-diameter ratio makes it a strong fit for shallow, precision holes in CNC machining centers, drill presses, and automatic screw machines. The coated finish enhances wear resistance and extends tool life in repetitive production cycles. It is sold individually and is appropriate for shops that require consistent, tight-tolerance hole quality in metalworking operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree drill point angle with X-thinned web reduces entry thrust and improves centering
• 2-flute spiral design with tapered web promotes chip evacuation in short holes
• Straight-cylindrical shank (0.1575 inches diameter) fits standard drill chucks and collets
• Coated finish for extended tool life in production drilling cycles
• Series 6300 screw machine length for compact reach in tight setups

Compatibility

Designed as a screw machine length replacement drill bit for use in CNC machining centers, automatic screw machines, and drill presses where a straight-cylindrical shank and 0.0945 inch diameter are required. Primary compatible workpiece materials are steel, alloy steel, and cast iron.

Installation Notes

Install into a compatible drill chuck or collet rated for a 0.1575 inch straight-cylindrical shank, ensuring the shank is fully seated and the chuck is properly torqued before operation. Power down the machine completely before changing tooling. Verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before starting the cut. Do not run this bit without confirming the machine setup meets the manufacturer tool specifications for carbide tooling.
