Osg 8597397 5/32 Inch Jobber Drill Bit Tin Vanadium Hss

Product Description

The OSG 8597397 is a jobber-length twist drill bit designed for high-performance drilling in metal and alloy workpieces. Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction compared to uncoated HSS. The 130-degree S-thinned point promotes self-centering and reduces thrust force, making it well suited for accurate entry on steel and stainless steel. Overall length is 75 millimeters with a 43-millimeter flute length and a straight cylindrical shank measuring 4.00 millimeters in diameter. The two-flute spiral design with a tapered web configuration supports efficient chip evacuation during through and blind hole drilling.

This bit is rated for use on steel, stainless steel, aluminum, aluminum alloys, and aluminum silicate. It is sized at 5/32 inch (0.1562 inch decimal, 3.97 millimeters) and fits within the 0.1500 to 0.2000 decimal inch drill size range. Common applications include blind hole drilling, cross hole drilling, standard drilling operations, and self-centering entry points. It is a single-piece unit packaged individually, suited for bench drilling, hand drill press, and CNC drilling operations where precision hole entry and clean flute clearing are priorities. Machinists, maintenance technicians, pipefitters, and HVAC installers working with sheet metal and structural steel components will find this bit appropriate for daily production use.

Key Features

• Vanadium high speed steel construction provides toughness and wear resistance in ferrous and non-ferrous materials
• Titanium nitride (TiN) coating reduces friction, extends cutting edge life, and improves chip flow
• 130-degree S-thinned point for self-centering entry and reduced axial thrust
• Two-flute regular spiral with tapered web configuration for consistent chip evacuation
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• No coolant-through requirement - suitable for dry or externally lubricated drilling setups

Compatibility

Designed for use on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Material performance codes P, M, and N. Fits standard drill chucks accepting a 4.00-millimeter straight cylindrical shank. Part of the OSG Series 1600 jobber-length drill bit line.

Installation Notes

Install into a properly sized drill chuck and verify secure clamping before operation. Use appropriate cutting fluid or lubricant when drilling stainless steel or harder steel alloys to preserve the TiN coating and cutting edge life. Secure the workpiece firmly before drilling to prevent bit walking, even with the S-thinned self-centering point. Inspect the cutting edges before each use and replace the bit if chipping or coating wear is evident.
