Guhring 9039430035050 Thread Forming Tap 6-32 Unc

Product Description

The GUHRING 9039430035050 is a thread forming tap designed for cold-forming internal threads in ductile materials without cutting or removing chips. Manufactured from High-Speed Steel-E-CO (cobalt-grade HSS) and finished with a TiCN coating, this tap delivers extended tool life in demanding production environments. It is configured for 6-32 UNC threads with a Modified Bottoming chamfer of 2-3 threads, allowing it to form threads close to the bottom of blind holes. The overall length is 2 inches with a thread length of 0.4724 inches and a tapping depth of 0.748 inches. Machinists and maintenance technicians working in CNC, manual, or hand-tapping applications install this tool.

This tap is suited for blind hole and through-hole threading operations in steel, stainless steel, cast iron, and non-ferrous metals. The 2BX class of fit with H5/H6 thread limits makes it appropriate for applications requiring tight, controlled thread tolerance. It is part of the GUHRING Series 3943, a roll-forming tap series designed for production use on CNC machining centers, drill presses, and tapping machines where a chipless threading process reduces the risk of chip-related damage in blind holes.

Key Features

• Chipless thread forming process eliminates chip buildup in blind holes
• TiCN coating improves surface hardness and wear resistance for longer tool life
• Modified Bottoming chamfer (2-3P) allows threading close to the bottom of blind bores
• H5/H6 thread limits hold 2BX class of fit tolerances consistently
• 4 oil grooves support lubrication flow during the forming process
• Right-hand thread direction, 3xD flute-to-diameter ratio for stable engagement

Compatibility

Designed for use in steel, stainless steel, cast iron, and non-ferrous metal workpieces requiring 6-32 UNC internal threads. Material application codes P, M, K, and N confirm suitability across this material range. Verify spindle speed, lubrication type, and torque limits against your machine specifications before use.

Installation Notes

Thread forming taps require a specific forming tap drill size — do not use a standard tap drill chart sized for cutting taps. Always apply an appropriate tapping fluid or cutting oil rated for the workpiece material before and during the operation. Ensure the tapping spindle is properly aligned to avoid tap breakage, especially in blind hole applications where bottoming contact is a risk. Qualified machinists or toolroom technicians should select proper RPM and feed rate according to the workpiece material and machine rigidity.
