Guhring 9008150160000 Spiral Point Tap M16 X 2 Cobalt

Product Description

The GUHRING 9008150160000 is a spiral point tap designed for through-hole threading in metric applications. Built from cobalt high-speed steel with a bright finish, this plug-chamfer tap cuts M16 x 2 threads to a 6H class of fit and D6/D7 thread limit. It runs 110 mm overall length with a 12 mm shank diameter and features a 3-flute geometry that pushes chips forward ahead of the cut — the defining characteristic of a spiral point design. It is suited for production and maintenance threading in steel workpieces. Licensed machinists and toolroom professionals are the primary users of this tap.

This tap is configured for through-hole threading applications in steel, where chip evacuation in a forward direction is practical and efficient. The plug chamfer provides a gradual lead-in, typically 3 to 5 threads of taper, making it appropriate for holes with sufficient depth clearance beyond the full thread length. The right-hand thread direction and 2 mm pitch correspond to standard M16 coarse thread specifications. Coolant-through capability is not included in this tap. It is a solid choice for CNC machining centers, drill presses, and manual tapping operations where the workpiece material is steel.

Key Features

• M16 x 2 metric coarse thread form at 6H class of fit and D6/D7 thread limit
• Cobalt high-speed steel construction for improved heat and wear resistance in steel cutting
• Spiral point geometry pushes chips forward for clean through-hole threading
• Plug chamfer with gradual lead-in for controlled thread engagement
• Bright finish — no coating — for straightforward re-sharpening compatibility
• 110 mm overall length with 12 mm shank diameter for standard tap holder fitment

Compatibility

Designed for through-hole threading of M16 x 2 metric coarse threads in steel workpieces. Compatible with standard tap holders and machine tool adapters accepting a 12 mm shank diameter. Fits GUHRING Series 815.

Installation Notes

This tap is installed by machinists and toolroom technicians in CNC or manual tapping operations. Secure the tap in a properly aligned tap holder or floating collet chuck to prevent cross-threading and tool breakage. Ensure the pilot hole is drilled to the correct minor diameter for M16 x 2 before tapping. Apply appropriate cutting fluid for steel, and never reverse the tap under power without first confirming the machine is set for synchronized tapping if used in a rigid-tap setup.
