Guhring 9039370048260 Machine Tap 10-24 Unc Cobalt Firex

Product Description

The GUHRING 9039370048260 is a 10-24 UNC straight flute machine tap designed for threading operations in blind holes and through-holes. Built from cobalt high-speed steel with a FIREX coating, it delivers extended tool life in abrasive materials and cast iron. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard taper or plug tap. With four flutes and a right-hand thread direction, this tap is suited for use in CNC machining centers, drill presses, and manual tapping setups where consistent 2B class-of-fit threads are required. Thread limit is H3/H4. Licensed machinists and toolroom technicians are the primary installers.

This tap is intended for metalworking applications involving abrasive materials and cast iron. The modified bottoming chamfer and 10-24 UNC thread form make it a practical choice when threading near the base of a blind hole or completing a through-hole in tougher ferrous workpieces. The FIREX coating reduces friction and heat buildup, extending service intervals in production environments. It is sold individually and is appropriate for both job shop and production floor use.

Key Features

• Modified bottoming chamfer for threading close to the bottom of blind holes
• Cobalt substrate with FIREX coating for improved wear resistance in abrasive and cast iron materials
• 4-flute straight flute design for stable thread forming in right-hand 10-24 UNC applications
• Class of fit 2B with H3/H4 thread limit for standard fastener thread tolerance
• No coolant-through requirement, compatible with flood or brush-applied cutting fluid
• Suitable for both blind hole and through-hole threading operations

Compatibility

Designed for threading 10-24 UNC right-hand threads in abrasive materials and cast iron. Applicable to blind hole and through-hole threading operations in standard machine tapping setups.

Installation Notes

This tap should be installed by a qualified machinist familiar with tapping speeds and feeds for cobalt tooling in ferrous materials. Ensure the workpiece is securely fixtured and the spindle is aligned before engagement. Apply an appropriate cutting fluid for cast iron or abrasive material to reduce heat and extend tap life. Do not reverse the tap under power without confirming the machine setup is designed for reversing operations.
