Osg 1410102101 Thread Forming Tap M3.5x0.60 Metric Coarse

Product Description

The OSG 1410102101 is a thread forming tap designed for cold-forming internal threads in ductile materials without cutting or removing chips. Built from cobalt high-speed steel with a steam oxide coating, this tap handles blind hole threading applications where chip evacuation is a concern. It carries an M3.5x0.60 metric coarse thread profile, a modified bottoming chamfer of 2 to 2.5 threads, and a 6H class of fit with a D6 thread limit. The 2.0 inch overall length and 0.141 inch shank diameter suit standard tap holders used in machine shop and production environments. Licensed machinists and tooling technicians are the primary installers.

This tap is suited for blind hole threading in a range of ferrous and non-ferrous materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The thread forming method displaces material rather than cutting it, producing stronger threads with better surface finish in ductile workpieces. It is a good fit for production machining, CNC tapping centers, and manual tapping operations where a right-hand M3.5x0.60 metric coarse thread is required. The HY-PRO NRT series is built for consistent performance across medium to high volume threading cycles.

Key Features

• Thread forming design eliminates chips, reducing the risk of chip packing in blind holes
• Cobalt high-speed steel construction improves heat and wear resistance over standard HSS
• Steam oxide coating provides lubricity and corrosion resistance during operation
• Modified bottoming chamfer allows threading close to the bottom of blind holes
• 6H class of fit with D6 thread limit for standard metric tolerance requirements
• Right-hand thread direction compatible with standard tapping chucks and holders

Compatibility

Designed for use in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring right-hand M3.5x0.60 metric coarse blind hole threads. Material application codes P and N apply.

Installation Notes

This tap should be installed by qualified machinists or tooling technicians familiar with thread forming operations. Power down or lock out any machine tool before loading or removing taps from holders. Thread forming taps require a properly sized forming tap drill hole, which differs from a cut tap drill size - consult the appropriate forming tap drill chart for M3.5x0.60 before drilling. Use a suitable tapping fluid or cutting oil rated for the workpiece material to extend tool life and maintain thread quality.
