Dormer E003M20 Series E003 HSS-E-PM Spiral Flute Machine Tap Metric with Steam Tempered Finish, ISO Standard, M20 x 2.50 mm Thread, 112 mm Length

The Dormer E003 M20 Spiral Flute Tap is engineered for creating M20 metric coarse threads in blind holes, representing a substantial thread size used in heavy machinery, large press tools, and major industrial fabrications. This professional-grade tap is essential for workshops handling heavy engineering, maintenance, and manufacturing operations. M20 threads provide exceptional load-bearing capacity and are frequently specified in large machine bases, heavy-duty lifting equipment, industrial gearbox housings, and structural steel assemblies where significant forces must be accommodated. The spiral flute design is critical at this thread size, efficiently evacuating the considerable chip volume produced during cutting to prevent dangerous chip packing in blind holes. With 4 flutes and a 29mm threading length, this tap handles most M20 applications. Manufactured from High Speed Steel Cobalt with steam tempering, this tap maintains sharp cutting edges when working through steel and cast
