Osg 1410103501 Thread Forming Tap M5x0.80 Metric Coarse

Product Description

The OSG 1410103501 is a thread forming tap designed for M5x0.80 metric coarse applications. Unlike cutting taps, thread forming taps displace material rather than cut it, producing stronger, work-hardened threads with no chips to clear. 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. With a plug chamfer of 4 to 4.5 threads, it is suited for through-hole threading operations where a gradual lead-in is needed. It is part of the OSG HY-PRO NRT series, built for production environments and general repair work across a range of metallic materials.

This tap is used in through-hole threading of M5x0.80 metric coarse threads in materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. It is a right-hand tap with a 6H class of fit and a D7 thread limit, making it appropriate for standard metric fastener fits in both light manufacturing and maintenance contexts. Machinists, tool and die makers, and maintenance technicians working with metric hardware will find this tap applicable to tapping machine and hand-tapping setups.

Key Features

• Thread forming design displaces material to create chip-free, work-hardened threads
• Cobalt construction provides heat and wear resistance in harder workpiece materials
• Steam oxide coating reduces friction and promotes coolant retention
• Plug chamfer (4 to 4.5 threads) allows gradual thread engagement for through-hole applications
• 6H class of fit with D7 thread limit meets standard metric tolerance requirements
• Right-hand thread direction compatible with standard tapping equipment and tap handles

Compatibility

Designed for through-hole threading of M5x0.80 metric coarse threads in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces.

Installation Notes

Thread forming taps require an appropriately sized forming tap drill — use the correct drill size for M5x0.80 form tapping rather than a standard tap drill chart value for cut taps. Secure the workpiece before tapping and apply a suitable cutting fluid or tapping compound for the workpiece material. Always back the tap out periodically when hand-tapping to maintain alignment and avoid tool breakage. Follow applicable shop safety practices and equipment manufacturer guidelines when using tapping machines or CNC equipment.
