Osg 1105201208 Straight Flute Tap M16x2 Bottoming 6H Ticn

Product Description

The OSG 1105201208 is a straight flute machine tap designed for threading M16x2.00 metric coarse holes in production and repair machining operations. Built from powdered metal and finished with a TiCN coating, it delivers increased surface hardness and wear resistance compared to standard HSS taps. The bottoming chamfer allows threading to the bottom of blind holes, and the 5-flute design supports chip control in through and shallow blind applications. Overall length is 110 millimeters with a thread length of 1-13/16 inches (24 millimeters). This tap is suited for machinists, tool and die technicians, and maintenance professionals working on metric-threaded assemblies.

The 1105201208 is rated for use in aluminum and cast iron. Its D7 thread limit and 6H class of fit make it appropriate for standard metric tolerance work where consistent thread form and fit are required. The right-hand thread direction and 5-flute configuration support smooth cutting in both manual and CNC tapping setups. The tap carries a 0.480 inch shank diameter, a square size of 0.360 inches, and a square length of 14.2875 millimeters, providing solid engagement in standard tap holders and adapters.

Key Features

• Bottoming chamfer for threading to the bottom of blind holes
• TiCN coating increases surface hardness and extends tool life in abrasive materials
• Powdered metal substrate for improved toughness over standard HSS
• 5-flute design supports chip management and consistent thread form
• 6H class of fit and D7 thread limit meet standard metric tolerance requirements
• Right-hand thread, compatible with standard CNC and manual tapping setups

Compatibility

Designed for use in aluminum and cast iron workpieces requiring M16x2.00 metric coarse right-hand threads. Fits standard tap holders and adapters accepting a 0.480 inch shank diameter with a 0.360 inch square drive.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians using a calibrated tap handle, tapping head, or CNC rigid tapping cycle. Power down and lock out all machinery before manual tool changes. Use appropriate cutting fluid for the workpiece material to prevent galling and extend tap life. Never reverse a bottoming tap under power without verifying the machine cycle supports it, as breakage risk increases in blind-hole applications without proper reversing.
