Guhring 9008030030000 Spiral Point Tap M3 X 0.5 Cobalt

Product Description

The GUHRING 9008030030000 is a cobalt spiral point tap designed for through-hole threading in metric applications. Built to M3 x 0.5 specifications with a 6H class of fit and D2/D3 thread limit, this tap cuts right-hand internal threads in steel and similarly hard materials. The plug chamfer style provides a gradual lead-in, making it well suited for threading through-holes where the tap can run past the workpiece. With 3 flutes and a bright finish, the 9008030030000 is a Series 803 production tool intended for machinists and tool-and-die professionals working on precision metric threading jobs.

This tap is intended for through-hole threading operations in steel and comparable ferrous materials. The M3 x 0.5 thread profile is common in small fastener applications across industrial, automotive, and mechanical assembly work. At 56 millimeters overall length with a 3.50-millimeter shank diameter, it is sized for use in standard tap holders, CNC tapping heads, and hand-tapping setups where metric M3 threads are required. Coolant-through is not supported, so external or flood coolant is the appropriate approach for lubricated cutting.

Key Features

• M3 x 0.5 metric thread profile with 6H class of fit and D2/D3 thread limit for consistent tolerance control
• Cobalt construction provides heat and wear resistance for threading steel and harder ferrous materials
• Plug chamfer lead-in optimized for through-hole threading applications
• 3-flute geometry promotes chip evacuation in through-hole cutting passes
• Bright finish with no coating for straightforward resharpening when needed
• Right-hand thread direction, compatible with standard tap holders and CNC tapping attachments

Compatibility

Designed for through-hole threading in steel workpieces requiring M3 x 0.5 metric right-hand threads. Fits standard tap holders and tapping chucks accepting a 3.50-millimeter shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Secure the workpiece fully before tapping and ensure the tap is aligned perpendicular to the hole to prevent tap breakage. Use an appropriate cutting fluid or tapping oil for steel; do not run this tap dry. When using in a CNC environment, verify the spindle speed and feed rate are appropriate for M3 cobalt taps in the target material before starting the cycle.
