Osg 8595159 Screw Machine Drill Bit 1/16 in Tin Hss

Product Description

The OSG 8595159 is a screw machine length drill bit designed for high-performance drilling in metalworking applications. Built from high speed steel with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction during cutting. The 1/16 inch (0.0625 inch) diameter and 140-degree faceted point angle make it well suited for starting clean, accurate holes without a center punch. Web thinning reduces thrust requirements and improves chip evacuation. A fast spiral flute and straight-cylindrical shank complete the design. Licensed machinists, tool-and-die techs, and general metalworking shops are the primary installers and users of this bit.

The OSG 8595159 is used in screw machine, CNC, and manual drill press operations where short overall length improves rigidity and reduces deflection. Its primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. The screw machine length body — approximately 1.654 inches overall — fits standard chuck setups where a shorter stub-style bit is preferred for precision work or tight clearance situations. This bit is sold individually and suits production and maintenance environments alike.

Key Features

• 1/16 inch (0.0625 inch) diameter with 140-degree faceted split point for accurate hole starting
• High speed steel construction with TiN coating for improved wear resistance and reduced heat buildup
• Web-thinned parallel web reduces cutting thrust and aids chip flow
• Fast spiral flute geometry promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks
• No coolant-through requirement — suitable for dry or conventional cutting fluid use

Compatibility

Rated for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Designed as an OSG Series 1100 screw machine length drill bit covering the 0.0000 to 0.1000 inch decimal inch size range.

Installation Notes

Install in a standard drill chuck, confirming that the shank seats fully and the chuck is tightened securely before operation. Power down the drill press or CNC machine and confirm zero-energy state before changing bits. Use appropriate cutting fluid for steel and stainless steel applications to maximize tool life. Wear approved eye protection and secure workpieces per shop safety standards before drilling.
