Osg 8594035 Jobber Drill Bit 3.5 Mm Ticn Hss

Product Description

The OSG 8594035 is a jobber-length twist drill bit designed for precision hole-making in a wide range of metallic workpiece materials. Built from vanadium high speed steel and finished with a TiCN (titanium carbonitride) coating, this bit delivers extended tool life and improved wear resistance compared to uncoated HSS tooling. It measures 3.5 mm in diameter with an overall length of 70 mm and a flute length of 39 mm. The 120-degree drill point angle and X-thinned web geometry reduce thrust force at entry and improve self-centering behavior. It is suited for production machining, toolroom work, and precision fabrication environments where consistent hole tolerances are required.

This drill bit is intended for use in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate workpieces. It performs in blind hole, cross hole, standard drilling, and self-centering applications. The straight-cylindrical shank accepts standard drill chucks, collet holders, and keyless chuck systems commonly found on CNC machining centers, drill presses, and hand-held power tools. The OSG Series 1800 product line is positioned as a high-performance general-purpose drill series appropriate for professional machine shop and industrial maintenance use.

Key Features

• TiCN coating provides increased surface hardness and lubricity for longer tool life in ferrous and non-ferrous materials
• X-thinned web point reduces entry thrust force and improves self-centering without a separate spotting operation
• 120-degree point angle suited for steel, stainless steel, cast iron, and aluminum applications
• Vanadium high speed steel substrate maintains hardness at elevated cutting temperatures
• Right-hand spiral flute with regular helix efficiently evacuates chips from blind and through holes
• Diameter tolerance of +0 to -0.018 mm ensures consistent, close-tolerance hole sizing

Compatibility

Designed as a high-performance jobber-length drill bit for use in standard drill chucks and collet systems accepting 3.5 mm straight-cylindrical shanks across CNC and manual drilling equipment.

Installation Notes

This bit is installed and removed by a licensed machinist or trained tool-and-die technician following standard tooling change procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the bit from any chuck or collet holder. Secure the shank to the full recommended grip depth to prevent pullout under cutting load. Follow the machine manufacturer and OSG cutting data recommendations for speed and feed when setting up for a new material or operation.
