Machine tap M3 is a precision cutting tool designed for cutting internal threads in metal, plastic, or wood materials. This class III tap is designed primarily for machine use, where it guarantees consistent and precise results in both serial production and individual work.
The tap features a characteristic transitional taper on the working part, visible in the photograph – it allows smooth introduction of the tool into the pre-drilled hole and even distribution of the cutting load. The precisely machined shank ensures reliable clamping in a machine chuck or tap chuck.
Key features and benefits include:
- M3 thread – standard metric thread, widely used in engineering, electronics, and assembly
- Precision class III – suitable for common engineering applications requiring reliable functionality
- NO finish (no surface treatment) – suitable for machining steel, cast iron, and non-ferrous metals
- Quality tool materials ensure long tool life
- Compatible with common machine tap chucks
This tap is an ideal choice for machine shops, maintenance workers, locksmiths, and DIY enthusiasts who need a reliable tool for cutting fine metric threads. Before use, we recommend drilling a hole of the correct diameter – for M3 thread, the standard pre-drilled diameter is 2.5 mm.
