Osg 8597455 Jobber Drill Bit 4.55mm Tin Hss

Product Description

The OSG 8597455 is a jobber-length twist drill bit designed for precision hole-making in metal and alloy workpieces. Built from vanadium high speed steel with a titanium nitride (TiN) coating, the bit delivers extended tool life and reduced friction during cutting. It measures 4.55 mm in diameter with a 91 mm overall length and a 47 mm flute length. The 120-degree split point geometry includes S-thinned web thinning for self-centering capability and reduced thrust force. A straight-cylindrical shank at 6.00 mm diameter fits standard drill chucks. Machinists, maintenance mechanics, and metal fabricators typically use this bit for production and repair drilling operations.

This bit is suited for drilling into steel, stainless steel, aluminum, aluminum alloys, and aluminum silicate. Typical applications include blind hole drilling, cross hole drilling, and self-centering operations in both manual and CNC setups. The regular spiral flute design promotes efficient chip evacuation in these materials. The 4.55 mm diameter falls within the 4.00 to 5.00 mm size range of the OSG Series 1600 jobber drill line, which targets high-performance general-purpose metal drilling.

Key Features

• Vanadium high speed steel construction for toughness and heat resistance
• Titanium nitride (TiN) coating reduces friction and extends cutting life
• S-thinned 120-degree split point promotes self-centering and lowers entry thrust
• Regular spiral flute with tapered web configuration for consistent chip flow
• Right-hand cut with 2-flute geometry suited for standard drilling operations
• No coolant-through requirement — compatible with dry or flood external coolant setups

Compatibility

Designed as a high-performance jobber-length drill bit for use in steel, stainless steel, aluminum, and aluminum alloy workpieces as part of the OSG Series 1600 product line.

Installation Notes

This bit is installed by machinists and metalworkers in standard drill chucks or CNC tool holders accepting a 6.00 mm straight-cylindrical shank. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Always wear appropriate eye protection and follow shop safety procedures when drilling metal. Do not exceed the recommended feed and speed range for the workpiece material.
