Spiral Flute Tap: M39x4.00 M, 4 Flutes, 6H Class of Fit, High Speed Steel, Fe Coated MPN:6635265

The Spiral Flute Tap with an M39x4.00 M size, 4 flutes, and a 6H Class of Fit made from High-Speed Steel coated with Fe is designed for tapping precision holes in various materials such as stainless steel or aluminum, with an ideal hole diameter tolerance of +/-0.005. Its unique design delivers faster penetration and prevents clogging while its 30-degree helix angle enables chip evacuation from the hole efficiently for continuous feed applications. As a result, this versatile spiral flute tap is applicable in sectors such as automotive, aerospace or industrial engineering requiring secure holes or fastening systems without roughing operations. Additionally, its cutting edges have been heat treated to provide an optimal balance between durability and flexibility that lasts longer with minimal deformation ensuring clean and smooth finishes needed on screw threads, studs or bushings production lines for automotive or electrical assemblies.
