Guhring 9044150200000 Spiral Point Tap M20x2.5 4 Flute

Product Description

The GUHRING 9044150200000 is a spiral point tap designed for through-hole threading in metric applications. Built from HSS-E cobalt steel with a steam oxide finish, it handles M20 x 2.5 thread sizes with a 4-flute, plug chamfer configuration. The 6H thread class and D8 thread limit make it suited for standard tolerance metric threading. At 4.469 inches overall length with a 2.362-inch thread length and 0.652-inch shank diameter, it fits standard tap holders used in production and maintenance machining. Licensed machinists and tool-and-die professionals use this tap for right-hand threading in steel workpieces.

This tap is intended for through-hole threading operations in steel. The spiral point geometry pushes chips forward ahead of the cutting edge, making it effective in through-hole applications where chip evacuation is straightforward. Series 4415 taps from GUHRING are used in both manual and CNC tapping operations. The cobalt-enriched HSS-E substrate improves heat resistance compared to standard HSS, which is relevant when tapping harder steel grades or running at higher spindle speeds.

Key Features

• M20 x 2.5 metric thread size with plug chamfer for through-hole starts
• 4-flute spiral point geometry pushes chips forward for clean through-hole threading
• HSS-E cobalt material improves wear and heat resistance in steel applications
• Steam oxide finish reduces friction and provides mild corrosion resistance
• 6H class of fit and D8 thread limit for standard metric tolerance requirements
• Right-hand thread direction, no coolant-through — compatible with standard tap holders

Compatibility

Designed for through-hole threading in steel workpieces requiring M20 x 2.5 metric threads to a 6H class of fit. Fits standard tap holders and collet chucks sized for a 0.652-inch shank diameter.

Installation Notes

Installation and use of this tap should be performed by qualified machinists familiar with tapping operations on manual or CNC equipment. Before beginning, confirm the pre-drilled hole diameter matches the recommended tap drill size for M20 x 2.5. Apply appropriate cutting fluid for steel to extend tool life, even though this tap does not require coolant-through supply. Verify spindle direction is set to right-hand rotation before engaging the tap.
