Description
Overview:
The Volkel M20 x 2.5 Plug Tap is a precision threading tool for cutting or restoring internal threads in blind holes. Made from durable, high-quality steel, it delivers reliable, repeatable results in maintenance, repair and light production tasks. A helical (spiral) flute design lifts swarf out of the hole to help protect the cutting edges and produce clean, accurate threads. This tap suits workshop and on-site use across construction and garden machinery, from mower housings and brackets to gear casings and fixtures. It can be used by hand with a tap wrench or in a suitable tapping head at controlled speed. The thread is ISO metric coarse M20 x 2.5, a common size for plant and machinery fasteners.
Key Features:
- M20 x 2.5 ISO metric coarse size for common machinery fasteners
- Helical flute efficiently evacuates swarf from blind holes for cleaner threads

Useful for restoring damaged threads during maintenance, fabricating custom mounts, or preparing holes for M20 fasteners in plant equipment, agricultural implements, workshop jigs and service repairs. Suitable for use on mild steel, aluminium, cast iron and brass with appropriate technique and lubrication.
