Guhring 9039420060000 Thread Forming Tap M6x1.00 Ticn

Product Description

The GUHRING 9039420060000 is a thread forming tap designed for cold-forming internal threads without cutting, reducing chip generation in the work zone. Built from High-Speed Steel-E-CO (cobalt-grade HSS) and coated with TiCN for added surface hardness and lubricity, this tap handles M6x1.00 Metric Coarse threads to a 6HX class of fit. The modified bottoming chamfer — 2 to 3 thread lead — allows threading close to the bottom of blind holes. Overall length is 2.5 inches with a thread length of 0.6299 inches and a tapping depth of 1.1811 inches. Machinists and toolroom operators use this tap in CNC machining centers and manual drill presses where tight-tolerance metric threads are required.

This tap is suited for blind-hole and through-hole threading applications across a range of workpiece materials including steel, stainless steel, cast iron, and non-ferrous metals — corresponding to material application codes P, M, K, and N. The Series 3942 design features five oil grooves to distribute forming lubricant evenly around the tap body during the cold-forming process. Right-hand thread direction is standard. Typical applications include precision machine components, fastener bosses, and structural hardware where M6 metric threads are specified to DIN or ISO standards.

Key Features

• Thread forming (chipless) operation reduces clogging in blind holes
• High-Speed Steel-E-CO (cobalt) construction for elevated heat and wear resistance
• TiCN coating increases surface hardness and reduces friction during forming
• Modified bottoming chamfer (2-3P lead) allows threading close to blind hole floors
• Five oil grooves ensure consistent lubricant distribution at the forming lobes
• Thread limit D8/D9 supports 6HX class of fit for standard metric tolerance zones

Compatibility

Designed for M6x1.00 Metric Coarse thread forming in steel, stainless steel, cast iron, and non-ferrous metal workpieces. Compatible with standard M6 tap holders and collet chucks accepting a 0.2550 inch (6.48 mm) shank diameter with a 0.1929 inch (4.90 mm) square drive.

Installation Notes

Thread forming taps require a forming-specific pilot hole diameter — consult the applicable ISO or DIN forming tap drill chart for M6x1.00 to determine the correct pre-drill size, as it differs from a cutting tap pilot hole. Use a suitable forming or tapping fluid rated for the workpiece material; dry forming will damage the tap and the workpiece thread. Secure the tap in a floating or tension-compression tap holder to absorb axial variation during the forming cycle. Ensure the spindle is fully stopped and the workpiece is firmly fixtured before engaging the tap.
