Osg 8670380 Screw Machine Drill Bit 0.1496in Carbide

Product Description

The OSG 8670380 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. At 0.1496 inches (3.80 mm) in diameter with a 140-degree split point, it delivers clean entry and reduced thrust in tough workpiece materials. The bit features a right-hand spiral flute with X-thinned web geometry and a tapered web configuration for improved chip evacuation. A straight-cylindrical shank with a 4.00 mm diameter seats securely in standard chucks and collets. This bit is built for production drilling environments where consistency, hole quality, and tool life are critical priorities for machinists and tool-and-die tradespeople.

The OSG 8670380 is suited for screw machine, CNC, and manual drill press applications targeting steel, alloy steel, and cast iron workpieces. Its screw machine length profile — shorter than jobber length — provides added rigidity and reduced deflection in close-tolerance work. The 2xD flute-by-diameter ratio and regular spiral flute type make it a practical choice for shallow-to-moderate depth holes where chip control and hole straightness matter. It is a Series 6300 tool positioned for high-performance general metalworking applications.

Key Features

• Solid carbide construction for superior hardness and wear resistance in ferrous metals
• 140-degree drill point angle reduces thrust and improves self-centering on entry
• X-thinned web with tapered web configuration supports aggressive chip clearing
• Right-hand cut, regular spiral flute for consistent chip evacuation
• Screw machine length body provides increased rigidity versus jobber length bits
• Straight-cylindrical shank compatible with standard chucks and collet systems

Compatibility

Designed for drilling steel, alloy steel, and cast iron workpieces. Compatible with standard straight-shank chucks and collet holders accepting a 4.00 mm shank diameter. Intended for use in screw machine, CNC, and drill press setups within the OSG Series 6300 product line.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle at a full stop and all power isolated. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation. Inspect the cutting edges and web for chips or wear before each use — solid carbide tooling is brittle and should not be used in setups with excessive runout or vibration. Follow the machine manufacturer and OSG Series 6300 recommended speeds and feeds for the target workpiece material.
