The OSG 8594080 is a jobber-length twist drill bit designed for high-performance metal drilling across a wide range of materials. Built from vanadium high speed steel with a titanium carbonitride (TiCN) coating, this bit delivers extended tool life and reduced friction in demanding production environments. The 8 mm diameter bit features a 120-degree split point with X-thinned web geometry that reduces thrust force and improves self-centering on entry. Overall length is 117 mm with a 75 mm flute length. Two right-hand spiral flutes with a regular helix provide efficient chip evacuation. Licensed HVAC techs, machinists, and maintenance professionals reaching for a go-to metal drill bit will find this a reliable production-grade option.
The 8594080 is suited for blind hole drilling, cross hole drilling, through-hole drilling, and self-centering applications. Primary workpiece materials include steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. The straight-cylindrical shank fits standard drill chucks and CNC toolholders without an adapter. This bit is part of OSG Series 1800, positioned as a high-performance jobber-length solution for both manual and machine drilling operations.
Designed for use in standard drill chucks and CNC toolholders accepting an 8 mm straight-cylindrical shank. Compatible workpiece materials include steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate per OSG Series 1800 specifications.
This bit is installed by machinists, maintenance technicians, and fabrication professionals using standard drill presses, hand drills, or CNC machining centers. Secure the straight-cylindrical shank fully into the chuck or collet before operation. This bit does not support coolant-through delivery; apply cutting fluid externally when drilling stainless steel or cast iron to manage heat. Inspect the cutting edge and TiCN coating before each use and remove the bit from service if chipping or coating breakdown is observed.
