Osg 8595222 Screw Machine Drill Bit 2.22mm Tin Hss

Product Description

The OSG 8595222 is a screw machine length drill bit designed for high-performance drilling in metalworking applications. Built from vanadium high speed steel with a TiN (titanium nitride) coating, this bit delivers extended tool life and improved wear resistance compared to uncoated HSS tooling. The 130-degree, 4-facet point geometry reduces walking at entry and allows faster penetration with less thrust. At 45.00 mm overall length and 2.22 mm diameter, it is sized for compact drilling in tight clearance setups typical of screw machine work and short-run production environments. Installation is handled by machinists and CNC operators working with drill presses, turret lathes, or machining centers.

This bit is suited for drilling steel, stainless steel, aluminum, and other non-ferrous materials. The screw machine length format keeps the tool shorter than jobber-length bits, improving rigidity and reducing deflection when drilling small-diameter holes in production runs. The 5xD flute-to-diameter ratio provides adequate chip evacuation for the target workpiece materials. The straight cylindrical shank measures 3.00 mm in diameter, fitting standard collets and drill chucks used in precision machining setups. It is a single-piece, individually packaged tool from OSG Series 1100.

Key Features

• TiN coating increases surface hardness and reduces friction for longer tool life in steel and non-ferrous applications
• 130-degree, 4-facet point geometry reduces drill walk and improves hole entry accuracy
• Vanadium high speed steel construction provides toughness for interrupted cuts and production drilling
• Web-thinned, tapered web design lowers cutting resistance and reduces thrust requirements
• Screw machine length format maximizes rigidity at small diameters compared to jobber-length alternatives
• Right-hand spiral flute with regular spiral type for consistent chip removal in through-hole and blind-hole drilling

Compatibility

Designed as an OEM-style replacement and production tooling option for use in drill presses, CNC machining centers, turret lathes, and screw machines accepting a 3.00 mm straight cylindrical shank. Primary workpiece materials include steel, stainless steel, aluminum, and non-ferrous alloys.

Installation Notes

This tool should be installed by qualified machinists familiar with cutting tool selection and machine setup. Ensure the spindle and work holding are fully stopped and de-energized before changing tooling. Verify collet or chuck bore matches the 3.00 mm shank diameter before clamping to avoid runout. Consult applicable workplace safety standards and machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
