The Dormer E003 M22 Spiral Flute Tap is designed for creating M22 metric coarse threads in blind holes, a large thread size typically specified in heavy industrial presses, large machine tools, and major structural fabrications. This substantial tap represents professional tooling for workshops handling the most demanding engineering and manufacturing applications. M22 threads are commonly required in large press frames, heavy-duty clamping systems, industrial rolling mills, and major structural assemblies where exceptional thread strength and load capacity are essential. The spiral flute configuration is vital at this thread size, as the large volume of chips produced must be efficiently evacuated upward to prevent the chip packing that can snap taps in blind holes. Featuring 4 flutes and a 29mm threading length, this tap handles most M22 applications. The High Speed Steel Cobalt construction delivers the hardness and wear resistance necessary for cutting large threads in steel and cast steel materials, whilst the steam tempered surface coating enhances cutting fluid retention for reduced friction and improved tool life. The cylindrical shank with square drive ensures positive engagement with tap wrenches or machine tool holders.
