Osg 8595191 Screw Machine Drill Bit 0.0752 in Tin Hss

Product Description

The OSG 8595191 is a screw machine length drill bit designed for high-performance drilling in metalworking and machining applications. Built from vanadium high speed steel with a TiN (titanium nitride) coating, it delivers extended tool life and reduced friction during cutting. The bit features a 140-degree, 4-facet point geometry and a web-thinned, parallel web configuration that improves chip evacuation and reduces the thrust force needed to start a hole. At 0.0752 inches in diameter with an overall length of 1.7323 inches, this stub-length bit is well suited for precision drilling in tight setups where rigidity matters.

This drill bit is rated for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. The screw machine length format makes it a standard choice in CNC machining centers, manual drill presses, and turret lathes where shorter flute length and reduced deflection are required. The straight cylindrical shank measures 0.1181 inches in diameter and seats securely in standard drill chucks and collet holders. It is sold individually and is part of the OSG Series 1100 high-performance drill line.

Key Features

• Vanadium high speed steel construction with TiN coating for extended tool life
• 140-degree, 4-facet point for fast, accurate hole entry with reduced walking
• Web-thinned parallel web design improves chip flow and lowers cutting thrust
• Screw machine (stub) length provides maximum rigidity and minimizes deflection
• Right-hand cutting, regular spiral flute for reliable chip evacuation
• Compatible with a wide range of ferrous and non-ferrous workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for screw machine, CNC turning center, and drill press applications requiring a straight-shank stub-length bit in the 0.0752-inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and machine tool operation. Ensure the machine spindle and chuck or collet are fully powered down and locked out before loading or changing the bit. Verify chuck or collet bore compatibility with the 0.1181-inch shank diameter before seating. Use appropriate cutting fluid or coolant for the workpiece material to optimize tool life, noting this bit does not support internal coolant-through delivery.
