Guhring 9039430048260 Thread Forming Tap 10-24 Unc

Product Description

The GUHRING 9039430048260 is a thread forming tap designed for cold-forming internal threads in ductile materials without cutting chips. Built from High-Speed Steel-E-CO (cobalt-bearing HSS) and coated with TiCN for increased surface hardness and heat resistance, this tap handles demanding production and maintenance threading work. It is configured for 10-24 UNC threads with a 2BX class of fit and a modified bottoming chamfer of 2-3 threads, making it effective for both blind hole and through-hole applications. Overall length is 2.382 inches, thread length is 0.551 inches, and tapping depth reaches 0.945 inches. Licensed machinists, toolmakers, and maintenance mechanics are the primary users.

This tap suits blind hole and through-hole threading in steel, stainless steel, cast iron, and non-ferrous metals. The right-hand, 10-24 UNC thread profile is common in light-duty fastener applications across HVAC sheet metal fabrication, electrical enclosures, and general mechanical assembly. The modified bottoming chamfer allows threading close to the bottom of a blind hole without fully bottoming out, reducing the setup adjustments needed compared to a standard plug chamfer. It is sized for use in CNC machining centers, drill presses, and hand-tapping operations wherever a 10-24 UNC thread is required.

Key Features

• Thread forming (chipless) design reduces clogging risk in blind holes
• High-Speed Steel-E-CO (cobalt) construction improves heat and wear resistance over standard HSS
• TiCN coating extends tool life in abrasive and high-temperature cutting conditions
• Modified bottoming chamfer (2-3 threads) enables threading near the base of blind holes
• 4 oil grooves promote lubricant distribution during the forming process
• Compatible with steel, stainless steel, cast iron, and non-ferrous metals (Material Application Codes P, M, K, N)

Compatibility

Designed for blind hole and through-hole threading applications in steel, stainless steel, cast iron, and non-ferrous metals. Suitable for use with standard 10-24 UNC tapping operations requiring a 2BX class of fit and H6 or H7 thread limit tolerances.

Installation Notes

Thread forming taps require proper lubrication — use a cutting or tapping fluid appropriate for the workpiece material before and during the tapping operation. Power down or lock out all equipment before changing or inspecting taps. Ensure the tap is held perpendicular to the workpiece to avoid thread distortion or tap breakage. Machinists should verify the correct drill size for thread forming (larger than cut-tap equivalents) before drilling pilot holes.
