Osg 1105200308 Straight Flute Tap M10x1.00 Metric Fine

Product Description

The OSG 1105200308 is a straight flute machine tap designed for cutting M10x1.00 metric fine internal threads in a bottoming configuration. Built from powdered metal and finished with a TiCN (Titanium Carbonitride) coating, this tap delivers hardness and wear resistance suited to production threading operations. It features 4 flutes with a right-hand thread direction and carries a D5 thread limit for close tolerance work. The overall length is 2-15/16 inches with a thread length of 1-1/4 inches. It is installed by machinists and tool-and-die professionals in both manual and CNC tapping applications.

This tap is suited for threading operations in aluminum and cast iron workpieces where a bottoming chamfer is required to cut threads close to the bottom of a blind hole. The Series 11052 design targets metric fine thread applications in manufacturing, maintenance, and repair environments. The TiCN coating reduces friction and extends tool life in abrasive materials. With a shank diameter of 0.381 inches and a square drive size of 0.286 inches, it fits standard tap holders and drive chucks used in machine shop environments.

Key Features

• M10x1.00 metric fine thread form with right-hand cutting direction
• Bottoming chamfer allows threading to within a few threads of blind hole bottom
• Powdered metal construction provides enhanced hardness and toughness over standard HSS
• TiCN coating improves wear resistance and reduces built-up edge in aluminum and cast iron
• D5 thread limit for consistent close-tolerance thread production
• 4 straight flutes suitable for short-chip materials such as cast iron and aluminum

Compatibility

Designed for use in aluminum and cast iron workpieces requiring M10x1.00 metric fine internal threads. Fits standard tap holders accepting a 0.381-inch shank diameter with a 0.286-inch square drive.

Installation Notes

Machine taps should be installed by qualified machinists following standard shop safety procedures. Ensure the spindle or tapping head is fully stopped and de-energized before changing tooling. Use appropriate tapping fluid or cutting oil for the workpiece material to reduce tool wear and improve thread finish. Verify tap holder alignment to avoid tap breakage, particularly in blind-hole bottoming operations where overtravel clearance is minimal.
