Osg 62536 Jobber Drill Bit 3.6 Mm Tin Vanadium Hss

Product Description

The OSG 62536 is a jobber length twist drill bit designed for precision drilling in metalworking and machining applications. Built from vanadium high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The bit measures 3.6 mm in diameter with an overall length of 71.00 mm and a flute length of 39.00 mm. The 130-degree split point geometry, combined with S-thinned web design, promotes self-centering entry and reduces the need for a center punch on most setups. Two spiral flutes evacuate chips efficiently in blind hole and through-hole operations. Machinists, tool and die technicians, and general metalworking professionals are the primary installers.

This bit is suited for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate in production and maintenance environments. It handles blind hole, cross hole, standard drilling, and self-centering applications. The straight-cylindrical shank with a 4.00 mm diameter fits standard drill chucks and collet holders used in benchtop drill presses, CNC machining centers, and hand-held power drills. The Series 1600 designation places it within OSG's high-performance jobber length line, intended for shops that require consistent dimensional accuracy across multiple workpiece materials.

Key Features

• Vanadium high speed steel construction for hardness and wear resistance in ferrous and non-ferrous materials
• Titanium nitride (TiN) coating reduces friction and extends cutting edge life
• 130-degree drill point angle with S-thinned web for self-centering and reduced thrust force
• Right-hand, regular spiral flute design promotes clean chip evacuation in blind and through holes
• Straight-cylindrical shank at 4.00 mm diameter fits standard drill chucks and collet holders
• Diameter tolerance of plus 0 to minus 0.018 mm ensures consistent hole size in close-tolerance work

Compatibility

Designed for use in standard drill chucks and collet-style toolholders that accept a 4.00 mm straight-cylindrical shank. Suitable for drilling steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Compatible with benchtop drill presses, knee mills, and CNC drilling operations within the material code groups P, M, and N.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with drill press or CNC toolholding procedures. Secure the shank fully in the chuck or collet and verify runout before cutting. For optimal tool life, use appropriate cutting fluid or coolant when drilling steel or stainless steel, even though this bit is not coolant-through rated. Inspect the cutting edges for wear or chipping between uses and replace when the TiN coating is visibly worn from the cutting tip.
