Dormer E003 HSS-E High Perf Mult-App Metric Coarse Spiral Flute Tap

The Dormer E003 M16 Spiral Flute Tap is designed for creating M16 metric coarse threads in blind holes, a substantial thread size commonly specified in heavy industrial machinery, structural steel fabrication, and large equipment assembly. This robust tap is essential for professional workshops handling heavy engineering and maintenance projects.

M16 threads provide significant load-bearing capacity and are frequently used in press frames, large motor mountings, construction equipment, and industrial gearboxes. The spiral flute configuration is critical for blind hole applications, pulling chips upward and preventing the dangerous chip packing that can break taps in larger thread sizes. This variant features 4 flutes rather than 3, providing additional cutting edges for improved performance in the larger diameter.

Manufactured from High Speed Steel Cobalt with steam tempering, this tap delivers the hardness and wear resistance needed for cutting through steel and cast steel materials. The 18mm threading length is suitable for most M16 applications, whilst the cylindrical shank with square drive ensures positive engagement with tap wrenches or machine holders.

Features and Benefits:
• M16 thread size for heavy-duty industrial and structural applications
• 4-flute design provides enhanced cutting performance in larger diameter
• Spiral flute geometry efficiently evacuates chips in blind holes
• HSS-E cobalt construction for extended tool life
• Steam tempered coating improves cutting fluid retention
