Osg 8597335 Jobber Drill 3.35mm Tin Hss 130 Deg

Product Description

The OSG 8597335 is a TiN-coated vanadium high speed steel jobber drill bit designed for precise, high-performance drilling in metal fabrication and general machining applications. It measures 3.35 mm in diameter with a 130-degree split point geometry that provides self-centering entry and reduces walking on hard surfaces. The overall length is 68.00 mm, with a 36.00 mm flute length and a 4.00 mm straight-cylindrical shank. The titanium nitride coating increases surface hardness and extends tool life in production drilling environments. This bit is suited for machinists, tool-and-die techs, and metalworking professionals who need consistent performance on steel and non-ferrous workpieces.

The OSG 8597335 is rated for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. It is appropriate for blind hole, cross hole, through-hole, and self-centering drilling operations. The regular spiral flute and S-thinned web configuration promote efficient chip evacuation and reduce thrust during feed. This bit fits standard drill chucks and CNC machining centers that accept a 4.00 mm straight shank. It is sold individually and is part of OSG Series 1600, a high-performance jobber-length line engineered for demanding metalworking conditions.

Key Features

• 3.35 mm diameter with a diameter tolerance of +0 to -0.018 mm for consistent hole sizing
• 130-degree S-thinned split point for self-centering entry without a center punch
• Titanium nitride (TiN) coating for extended tool life and reduced friction
• Vanadium high speed steel construction suited for steel and stainless steel drilling
• Regular right-hand spiral flute with tapered web for efficient chip evacuation
• 4.00 mm straight-cylindrical shank compatible with standard drill chucks and CNC toolholders

Compatibility

Designed for use in standard drill chucks and CNC machining center toolholders accepting a 4.00 mm straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Part of OSG Series 1600, drill bit size range 3.00 mm to 4.00 mm (0.1000 to 0.1500 decimal inch).

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with cutting tool setup. Ensure the drill chuck or collet is fully tightened and the workpiece is securely fixtured before operation. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling stainless steel or deep holes to manage heat. Inspect the cutting edge before each use and replace the bit if chipping or excessive wear is observed.
