Osg 1625010244 Thread Forming Tap 10-24 Unc Cobalt Ticn

Product Description

The OSG 1625010244 is a thread forming tap designed for cold-forming internal threads in a wide range of metals without cutting chips. Part of the OSG EXOPRO XPF Series 16250, this tap produces a 10-24 UNC thread to a 3B class of fit with a modified bottoming chamfer of 2.5 to 3 threads. Constructed from cobalt high-speed steel and finished with a TiCN coating, the 1625010244 offers elevated heat and wear resistance suited to demanding production and maintenance environments. Thread direction is right hand. This tap is installed by machining professionals and maintenance technicians using standard tapping equipment.

The 1625010244 is suited for both blind hole and through-hole threading applications. Its material compatibility covers a broad spectrum including aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium, corresponding to material application codes P, M, N, and H. The modified bottoming chamfer allows threading close to the bottom of blind holes, making this tap a practical choice in precision machining, fabrication shops, and field repair scenarios where thread depth control is critical.

Key Features

• Thread forming design produces threads without cutting chips, reducing tap breakage risk in ductile materials
• Cobalt construction provides superior red hardness and wear resistance compared to standard HSS
• TiCN coating reduces friction and extends tool life in abrasive and high-temperature applications
• Modified bottoming chamfer (2.5 to 3 threads) enables threading close to the bottom of blind holes
• Compatible with blind hole and through-hole threading applications across a wide material range
• Right-hand thread direction, 3B class of fit, H4 thread limit for accurate fitment control

Compatibility

Designed for threading 10-24 UNC blind and through-holes in aluminum, cast aluminum, carbon steel, alloy steel, die steel, hardened steel, stainless steel, high-nickel alloys, and titanium. Material application codes P, M, N, and H are supported.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tapping head, tapping attachment, or CNC machine set to the correct feed rate for a 10-24 UNC pitch. Power down or de-energize all equipment before performing manual tapping operations on assemblies. Use appropriate cutting fluid or tapping compound recommended for the workpiece material to maximize tool life and thread quality. Thread forming taps require a properly sized forming tap drill hole, which differs from a standard cut-tap drill size — verify the correct drill diameter for the material before starting.
