Osg 1400118000 Thread Forming Tap 10-24 Unc Bottoming Cobalt

Product Description

The OSG 1400118000 is a thread forming tap in the HY-PRO NRT series, designed for cold-forming internal threads without cutting or producing chips. Manufactured from cobalt with a bright finish, this bottoming-style tap carries an H5 thread limit and is sized for 10-24 UNC threads. With a 1 to 1.5 chamfered thread lead, it seats quickly to the bottom of a blind hole, maximizing usable thread depth. The overall length is 2.375 inches, with a shank diameter of 0.194 inches. Professionals in precision machining, maintenance, and industrial fabrication rely on this tap for high-strength thread production in demanding materials.

This tap is engineered for blind hole threading applications across a range of workpiece materials including alloy steel, carbon steel, die steel, hardened steel, aluminum, and stainless steel. Its bottoming chamfer geometry makes it well suited for situations where full thread engagement close to the bottom of a hole is required. The cold-forming action produces stronger threads with better surface finish compared to cut taps, making it a preferred choice in production and repair environments where joint integrity matters.

Key Features

• 10-24 UNC thread size with right-hand thread direction
• Bottoming chamfer with 1 to 1.5 chamfered threads for near-bottom thread engagement in blind holes
• Cobalt construction with bright finish for durability in hard and abrasive materials
• H5 thread limit for controlled fit tolerance
• No coolant-through design; suitable for standard tapping setups
• Compatible with alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel

Compatibility

Designed for blind hole threading in alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces requiring 10-24 UNC internal threads.

Installation Notes

This tap is installed by machinists and maintenance technicians using a standard tap wrench, tapping head, or CNC tapping cycle. Power down and secure the workpiece before beginning. Use an appropriate tapping fluid or cutting oil for the workpiece material to reduce friction and extend tool life. Do not exceed the recommended tapping depth of 0.866 inches, and avoid forcing the tap against the bottom of the hole to prevent breakage.
