Osg 8656200 Jobber Length Drill Bit 12 Mm Hss WD1

Product Description

The OSG 8656200 is a jobber-length drill bit designed for precision hole-making in metal, alloy, and general-purpose materials. Built from vanadium high speed steel with a WD1 coating, it delivers extended tool life in demanding production and maintenance applications. The bit features a 120-degree faceted point angle with S-thinned web geometry, which reduces thrust force on entry and improves centering accuracy. At 12 mm in diameter with a 158 mm overall length and a 101 mm flute length, it fits standard jobber-length reach requirements. Machinists, toolmakers, and maintenance technicians install this bit in CNC machines, drill presses, and hand-held power drills.

This drill bit is suited for high-performance drilling in ferrous and non-ferrous materials across job shop, manufacturing, and MRO environments. The fast spiral flute type promotes efficient chip evacuation, making it effective in deeper holes where chip packing is a concern. The straight-cylindrical shank seats securely in standard 3-jaw chucks and quick-change collet systems without requiring a taper adapter. It is sold as an individual bit and is appropriate for both production runs and single-use maintenance repairs.

Key Features

• Vanadium high speed steel construction for elevated heat and wear resistance

Compatibility

Designed as a jobber-length replacement or production drill bit for use in standard 3-jaw chucks and collet holders accepting a 12 mm straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill press, lathe, or CNC spindle equipment. Secure the shank fully in the chuck or collet and confirm runout before drilling. Always power down and lock out the machine before changing bits. Do not exceed the recommended feed and speed parameters for the workpiece material and machine setup.
