Osg 8597508 Jobber Drill Bit 5.08mm Tin Vanadium Hss

Product Description

The OSG 8597508 is a jobber-length twist drill bit built from vanadium high speed steel with a titanium nitride (TiN) coating for extended wear resistance. It carries a 5.08 mm cutting diameter, a 120-degree split-point (S-thinned) tip, and a 96 mm overall length with a 52 mm flute length. The straight-cylindrical shank measures 6.00 mm in diameter. The S-thinned web reduces thrust load at entry, allowing cleaner starts without a center punch on many materials. This bit is suited for machinists, tool-and-die technicians, and maintenance trades drilling in steel, stainless steel, aluminum, and aluminum alloys.

The OSG 8597508 is designed for a wide range of drilling operations including blind holes, cross holes, and self-centering applications. It performs in steel and stainless steel as well as aluminum and aluminum alloy workpieces. The regular spiral geometry and two-flute configuration promote efficient chip evacuation in both short and interrupted cuts. It is appropriate for use in drill presses, CNC machining centers, and hand-held power drills where a straight-shank jobber bit is required.

Key Features

• Vanadium high speed steel construction for toughness in hard and abrasive materials
• Titanium nitride (TiN) coating reduces friction and extends tool life compared to uncoated HSS
• S-thinned point reduces entry thrust and improves self-centering without a pilot hole
• 120-degree included point angle suited for steel, stainless steel, and aluminum
• Two-flute regular spiral geometry promotes positive chip evacuation
• No coolant-through requirement — compatible with standard flood or mist coolant setups

Compatibility

Designed for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Suitable for blind hole, cross hole, standard drilling, and self-centering applications per OSG Series 1600 specifications.

Installation Notes

This bit is installed by a machinist or maintenance technician into any drill chuck or collet accepting a 6.00 mm straight-cylindrical shank. Secure the shank fully in the chuck before operation and confirm runout is within acceptable limits for the application. Always power down and de-energize the machine before changing bits. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
