Osg 1410103701 Thread Forming Tap M6x1.00 Metric Coarse

Product Description

The OSG 1410103701 is a bottoming-chamfer thread forming tap designed for M6x1.00 metric coarse threads in blind hole applications. Unlike cutting taps, thread forming taps cold-form the thread profile by displacing material rather than cutting it, producing stronger threads with no chips to evacuate. This tap is manufactured from cobalt high-speed steel and finished with a steam oxide coating that reduces friction and improves lubrication retention during the tapping cycle. It carries a 6H class of fit with a D8 thread limit, making it appropriate for standard metric threaded fastener assemblies. Machinists, toolroom operators, and production line technicians working in precision metalworking environments are the primary users.

This tap is rated for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. The bottoming chamfer — ground to 1 to 1.5 thread pitches — allows threading to the bottom of a blind hole with minimal clearance at the end of the bore. It is well suited to CNC machining centers and manual tapping operations where chip-free thread forming is required. The HY-PRO NRT series is OSG's cold-forming tap line targeting general-purpose production threading in a wide range of ferrous and non-ferrous materials.

Key Features

• Thread forming (chipless) design strengthens threads by cold-working the material
• Bottoming chamfer (1 to 1.5P) enables threading to the bottom of blind holes
• Cobalt HSS construction provides elevated heat and wear resistance
• Steam oxide finish reduces friction and promotes lubricant adhesion
• 6H class of fit with D8 thread limit suits standard metric fastener assemblies
• Right-hand thread direction; does not require coolant-through capability

Compatibility

Designed for blind hole thread forming in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring M6x1.00 metric coarse, 6H class internal threads.

Installation Notes

Thread forming taps require a drilled hole sized specifically for form tapping — the recommended forming drill diameter is larger than a standard tap drill and must be confirmed before use. A cutting fluid or tapping compound appropriate for the workpiece material should be applied to reduce forming torque and extend tool life. Secure the tap in a rigid holder or tapping chuck with appropriate torque control to avoid overloading the tap in harder materials. Ensure the workpiece is fully clamped and the spindle is aligned square to the bore before beginning the tapping cycle.
