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

The Dormer E003 M2 Spiral Flute Tap is designed for creating M2 metric coarse threads in blind holes, the smallest size in this professional range. This precision tap is essential for fine engineering work, electronics assembly, instrumentation, and delicate mechanical components where space constraints demand the smallest thread sizes.

M2 threads are commonly specified in precision instruments, electronic device housings, small control mechanisms, watch components, and miniature assemblies where extremely limited space necessitates tiny but functional threads. The spiral flute design is vital even at this minute diameter, as chips must be evacuated upward from blind holes to prevent the easily-damaged threads and fragile tap breakage. Featuring 2 flutes (rather than 3) and an 8mm threading length, this tap is optimised for the unique challenges of micro-threading.

Manufactured from High Speed Steel Cobalt with steam tempering, this tap maintains the extremely sharp cutting edges required for producing clean threads at such a small diameter. The coating helps retain cutting fluid, which is crucial for preventing the friction and heat that can instantly break micro-diameter taps. The cylindrical shank with square drive allows secure mounting in precision tap wrenches for carefully controlled threading operations.

Features and Benefits:
• M2 thread size for precision engineering and micro-assemblies
• 2-flute design optimised for smallest diameter applications
• Spiral flute geometry essential for chip evacuation in tiny blind holes
• HSS-E cobalt material for durability at micro-diameters
• Steam tempered coating critical for friction reduction
