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

The Dormer E003 M18 Spiral Flute Tap delivers professional-grade performance for creating M18 metric coarse threads in blind holes, a large thread size typically required in heavy industrial equipment, press tooling, and major structural assemblies. This substantial tap is designed for demanding professional applications where thread integrity and strength are paramount.

M18 threads are commonly specified in large machine tool assemblies, heavy-duty clamping systems, and industrial presses where high clamping forces and structural loads must be accommodated. The spiral flute design is essential at this thread size, as the larger chip volume produced during cutting must be efficiently evacuated upward to prevent tap breakage. Featuring 4 flutes and an extended 29mm threading length, this tap handles deeper blind hole applications.

The High Speed Steel Cobalt construction provides the hardness and heat resistance necessary for cutting larger threads in steel and cast steel materials, whilst the steam tempered surface coating enhances cutting fluid retention for improved tool life. The cylindrical shank with square drive ensures secure mounting in both manual and power-driven applications.

Features and Benefits:
• M18 thread size for heavy industrial and large assembly applications
• 4-flute configuration for efficient cutting in larger diameter threads
• Extended 29mm threading length accommodates deeper blind holes
• HSS-E cobalt material delivers superior wear resistance
• Spiral flute design prevents chip accumulation and tap breakage
