Guhring 9039070048260 Spiral Point Tap 10-24 Unc Tin

Product Description

The GUHRING 9039070048260 is a spiral point tap designed for through-hole threading in a 10-24 UNC thread form. Built from high-speed steel with powder metallurgy (HSS-E-PM), it delivers greater toughness and wear resistance than standard HSS taps. A titanium nitride (TiN) coating reduces friction and extends tool life in demanding materials. With a 3-flute, plug chamfer configuration and a right-hand thread direction, it is suited for production threading in machine tapping operations. Licensed machinists and tooling technicians use this tap in CNC machining centers, drill presses, and tapping machines where consistent 2B class-of-fit threads are required. The overall length is 2.382 inches with a thread length of 0.551 inches.

This tap is rated for threading stainless steel and other tough alloys where HSS-E-PM construction provides the edge retention needed for reliable results. The spiral point geometry pushes chips forward through the hole, making it effective in through-hole applications where chip evacuation from the cutting zone is critical. It carries a thread limit of H3/H4, appropriate for standard 2B tolerance threading. This is a Series 3907 tap intended for use in automated or hand-held tapping setups where plug chamfer entry and controlled chip flow are priorities.

Key Features

• 10-24 UNC thread form with right-hand direction and 2B class of fit
• HSS-E-PM construction for improved toughness and wear resistance over conventional HSS
• TiN coating reduces friction and extends service life in stainless steel and hard alloys
• Spiral point geometry pushes chips forward, optimized for through-hole threading
• 3-flute, plug chamfer design provides controlled entry and consistent thread formation
• H3/H4 thread limit for standard 2B tolerance compliance

Compatibility

Designed for through-hole threading applications in stainless steel and similar materials. Suitable for use with standard machine tapping equipment accepting taps with a 0.194-inch shank diameter. Compatible with cutting fluids and coolants applied externally; this tap does not include coolant-through capability.

Installation Notes

Installation should be performed by a qualified machinist familiar with tapping speeds and feeds for the workpiece material. Ensure the spindle is properly aligned and the tap holder provides adequate float to prevent thread damage. Power down the machine and secure the workpiece firmly before tool changes. Use appropriate cutting fluid for stainless steel to prevent galling and premature tap wear.
