Osg 1410103500 Thread Forming Tap M5x0.80 Cobalt Plug

Product Description

The OSG 1410103500 is a thread forming tap designed for cold-forming internal threads without cutting or generating chips. Built from cobalt high-speed steel with a bright finish, this plug-chamfer tap produces M5x0.80 metric coarse threads in through-hole applications. The cobalt construction provides elevated heat resistance and hardness retention, making it suitable for demanding materials and higher-speed tapping operations. With an overall length of 2.3622 inches and a thread length of 0.3937 inches, this tap is sized for standard machine tapping setups. It is installed by machinists and toolroom professionals working in production or maintenance environments.

This tap is intended for through-hole threading in a range of metals including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The plug chamfer with 4 to 4.5 chamfered threads makes it well suited for blind or through holes where a gradual thread lead-in is appropriate. It belongs to the OSG HY-PRO NRT series, which is engineered for roll-form tapping where superior thread strength and smooth finish are required. Typical applications include CNC machining centers, drill presses, and tapping machines in both job shop and production settings.

Key Features

• Bright finish suitable for a wide range of metals and cutting fluid compatibility
• Plug chamfer with 4 to 4.5 chamfered threads for controlled thread engagement lead-in
• Thread forming design eliminates chips, reducing tap breakage risk and improving thread strength
• Right-hand thread direction, Class 6H fit, Thread Limit D7 for standard metric tolerance control
• Part of the HY-PRO NRT series for consistent roll-form tapping performance

Compatibility

Designed for through-hole threading applications requiring M5x0.80 metric coarse threads in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. Compatible with standard machine tapping setups accepting a 0.1940-inch shank diameter.

Installation Notes

This tap is installed by machinists using CNC tapping cycles, rigid tapping attachments, or manual tapping machines. Ensure the workpiece is securely fixtured and the spindle is aligned with the hole axis before tapping. Use an appropriate cutting or forming fluid compatible with the workpiece material to reduce friction and extend tap life. Do not reverse the tap under load without confirming the machine cycle supports synchronized reversal.
