Osg 8594064 Jobber Drill 6.40mm Ticn Vanadium Hss

Product Description

The OSG 8594064 is a jobber-length drill bit engineered for high-performance drilling in a wide range of metalworking applications. Manufactured from vanadium high speed steel and finished with a TiCN (titanium carbonitride) coating, this bit delivers extended tool life and reduced heat buildup compared to uncoated HSS tooling. The cutting geometry features a 120-degree point angle with X-thinned web configuration, which reduces thrust force and promotes self-centering on entry. At 6.40 mm in diameter with a 101.00 mm overall length and a 63.00 mm flute length, it fits standard drill chucks and CNC toolholders with a straight-cylindrical shank. Two spiral flutes with regular helix clear chips efficiently during operation. Installed by machinists, tool-and-die tradespeople, and maintenance mechanics on drill presses, lathes, and CNC machining centers.

The OSG 8594064 is suited for drilling blind holes, cross holes, and through holes in ferrous and non-ferrous materials. Its primary workpiece material ratings cover steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate. The Series 1800 designation places it in OSG's high-performance jobber drill lineup, appropriate for production environments where tool consistency and dimensional accuracy are required. Diameter tolerance is held to +0 to -0.022 mm, making it suitable for applications where hole size consistency matters before reaming or tapping.

Key Features

• TiCN coating reduces friction and extends tool life in steel and stainless steel cutting
• X-thinned web point lowers thrust requirement and supports self-centering entry
• 120-degree point angle suited for drilling steel, cast iron, and aluminum
• Right-hand cut, regular spiral flute for standard drill press and CNC use
• Straight-cylindrical shank fits standard Jacobs-style chucks and collet holders
• Diameter tolerance of +0 to -0.022 mm for consistent hole sizing

Compatibility

Designed as a direct-fit jobber drill for any drill press, manual lathe, or CNC machining center accepting a 6.40 mm straight-cylindrical shank. Rated for use in steel, alloy steel, stainless steel, cast iron, aluminum, aluminum alloy, and aluminum silicate workpieces per OSG Series 1800 material codes P, M, K, and N.

Installation Notes

A licensed machinist or qualified maintenance mechanic should secure the shank fully in a properly sized chuck or collet before operation. Ensure the spindle and workpiece are firmly clamped and that all guarding is in place before starting the cut. Do not use coolant-through setups with this bit, as it is not rated for internal coolant delivery. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge condition is degraded to avoid oversized holes or workpiece damage.
