Osg 8597386 Jobber Drill Bit 0.1520 in 130 Deg Tin Hss

Product Description

The OSG 8597386 is a jobber-length twist drill bit designed for high-performance drilling in steel, stainless steel, aluminum, and aluminum alloys. It measures 0.1520 inches (No. 24 wire gauge) in diameter and features a 130-degree split point with S-thinned web geometry for self-centering entry without a center punch. The bit is manufactured from vanadium high speed steel and carries a TiN (titanium nitride) coating that extends cutting life in production and maintenance drilling environments. With a straight-cylindrical shank and right-hand spiral flute, it seats directly in standard drill chucks and CNC toolholders.

This bit is suited for blind hole, cross hole, and through-hole drilling operations across light manufacturing, maintenance, and fabrication work. Its 0.1520-inch diameter falls within the 0.1500 to 0.2000 inch range common in precision fastener and tapping prep applications. The two-flute regular spiral design provides efficient chip evacuation in both ferrous and non-ferrous materials. It is a single-piece, individually packaged bit appropriate for use in hand drills, drill presses, and CNC machining centers.

Compatibility

Designed for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate. Suitable for blind hole, cross hole, general drilling, and self-centering applications per OSG Series 1600 specifications. Compatible with standard straight-shank drill chucks and CNC toolholders accepting a 4.00 mm shank diameter.

Installation Notes

Machinists and maintenance technicians should ensure the drill chuck or collet is properly tightened and the workpiece is securely clamped before beginning any drilling operation. Power down and de-energize the machine before changing tooling. Coolant-through is not supported on this bit; apply cutting fluid externally when drilling stainless steel or deep holes to manage heat buildup. Follow applicable OSHA machine guarding and PPE requirements during operation.
