Osg 8597227 Jobber Drill Bit 2.27mm Tin Hss 130 Deg

Product Description

The OSG 8597227 is a jobber-length twist drill bit designed for precision hole-making in metal and alloy workpieces. Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this bit runs at elevated speeds without excessive wear. It measures 2.27 mm in diameter with a 59 mm overall length and a 3.00 mm straight-cylindrical shank. The 130-degree split-point (S-thinned) tip reduces thrust, starts on contact without walking, and self-centers without a pilot hole. The regular spiral flute with tapered web provides efficient chip evacuation in both through and blind hole applications. Machinists, tool and die tradespeople, and CNC operators are the primary users.

This bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Typical applications include blind hole drilling, cross hole operations, general drilling, and self-centering entry cuts. The 2-flute configuration handles a broad range of production and maintenance machining scenarios where a small-diameter, high-performance jobber bit is needed. It fits the OSG Series 1600 lineup, which covers the 2.00 mm to 3.00 mm diameter range in decimal inch sizes from 0.0500 to 0.1000 inch.

Key Features

• Vanadium high speed steel construction with TiN coating for extended tool life at higher cutting speeds
• 130-degree S-thinned split point self-centers on contact, eliminating the need for a center punch or pilot hole
• Regular spiral flute with tapered web promotes consistent chip evacuation in blind and through holes
• 2.27 mm diameter with a 3.00 mm straight-cylindrical shank for broad collet and chuck compatibility
• Right-hand cut, 2-flute geometry compatible with standard CNC and manual drill press setups
• Rated for steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpiece materials

Compatibility

Designed as an OSG Series 1600 jobber-length drill bit for use in standard straight-shank drill chucks and collet systems accepting a 3.00 mm shank. Compatible workpiece materials per OSG specification include steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. No specific machine model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with speeds, feeds, and chip load calculations for small-diameter high speed steel bits. Secure the shank fully in the chuck or collet and verify runout before engaging the workpiece. Power down and de-energize the machine spindle completely before changing tooling. Avoid excessive feed pressure on small-diameter bits, as this increases the risk of bit deflection or breakage.
