Osg 1415004708 Thread Forming Tap M10x1.25 Bottoming Ticn

Product Description

The OSG 1415004708 is a thread forming tap designed for M10x1.25 metric fine threading in blind hole applications. Part of the EXOTAP VP-NRT series, it uses a cold-forming process that displaces material rather than cutting it, producing stronger threads with no chips to clear. Constructed from powdered metal high-speed steel (PM-HSS) and finished with a TiCN coating, it delivers high hardness and wear resistance across demanding production environments. The bottoming chamfer with 1 to 1.5 chamfered threads allows threading close to the bottom of a blind hole. Overall length is 2.9134 inches with a tapping depth of 1.252 inches.

This tap is suited for use in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum workpieces. The thread forming design makes it especially effective in ductile materials where chip evacuation is a concern. Typical installation scenarios include CNC machining centers, tapping heads, and manual tapping fixtures in production shops, tool rooms, and maintenance environments. Right-hand thread direction and a D9 thread limit support standard 2B class of fit tolerances for metric fine fastener applications.

Key Features

• Thread forming (chipless) design produces stronger threads and eliminates chip-related tap breakage in blind holes
• Powdered metal high-speed steel construction provides superior toughness and heat resistance over standard HSS
• TiCN coating reduces friction and extends tool life in ferrous and non-ferrous materials
• Bottoming chamfer with 1 to 1.5 chamfered threads maximizes usable thread depth in blind holes
• D9 thread limit holds 2B class of fit for M10x1.25 metric fine threads
• Compatible with coolant-external setups; no through-coolant required

Compatibility

Designed for M10x1.25 metric fine blind hole threading in alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. Suitable for use with standard tapping chucks, CNC rigid tapping, and tapping heads that accept a 0.381-inch shank diameter.

Installation Notes

Thread forming taps should be installed by a machinist or toolroom technician familiar with tapping speeds and feed rates for the specific workpiece material. Ensure the spindle is properly aligned with the hole before engaging to prevent tap damage or thread distortion. Use a thread-forming-compatible tapping fluid or cutting oil appropriate for the workpiece material. Always verify machine RPM and feed rate are set for form tapping, as these differ from cutting tap parameters.
