Osg 62561 Jobber Length Drill Bit 6.1 Mm Tin Hss

Product Description

The OSG 62561 is a jobber-length twist drill bit engineered for high-performance drilling in ferrous and non-ferrous materials. Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction compared to uncoated HSS tooling. It cuts in a right-hand direction with a standard spiral flute and features an S-thinned point at 120 degrees for improved self-centering and reduced thrust. The straight-cylindrical shank measures 8.00 mm in diameter, making it compatible with standard drill chucks. Machinists, toolroom technicians, and maintenance mechanics are the primary users of this Series 1600 bit.

This bit is suited for drilling blind holes, cross holes, and through-holes in steel, stainless steel, aluminum, aluminum alloys, and aluminum silicate. It performs well in both manual and CNC-assisted drilling operations where consistent hole quality and dimensional accuracy are required. The 120-degree point angle is a general-purpose geometry appropriate for a wide range of these materials. Overall length is 107.00 mm with a flute length of 63.00 mm, positioning it in the standard jobber-length category for everyday production and maintenance drilling tasks.

Key Features

• Vanadium high speed steel construction with TiN coating for extended wear resistance
• 120-degree S-thinned point promotes self-centering and lowers entry thrust force
• Right-hand, regular spiral flute with tapered web configuration for efficient chip evacuation
• Straight-cylindrical 8.00 mm shank fits standard drill chucks without adapters
• Rated for steel, stainless steel, aluminum, and aluminum alloy workpieces
• Series 1600 high-performance grade; diameter tolerance held to +0 to -0.022 mm

Compatibility

Designed for use in drilling applications on steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces; suitable for blind hole, cross hole, standard drilling, and self-centering operations across general machining and maintenance environments.

Installation Notes

Install into a compatible drill chuck or collet rated for the 8.00 mm straight-cylindrical shank before use. Ensure the machine spindle is fully stopped and the workpiece is securely clamped before beginning any drilling operation. Apply appropriate cutting fluid for stainless steel or deep-hole applications to manage heat and chip load. Inspect the TiN coating and cutting edges before each use and replace the bit if chipping or excessive wear is observed.
