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

The Dormer E003 M8 Spiral Flute Tap is designed for creating M8 metric coarse threads in blind holes, a highly popular medium thread size used extensively in automotive work, machinery assembly, and general engineering applications. This versatile tap is ideal for both professional mechanics and DIY enthusiasts handling everyday threading tasks.

M8 threads are extremely common in automotive components, machinery housings, mounting brackets, and general mechanical assemblies where a good balance between strength and size is required. The spiral flute configuration pulls chips upward and away from the cutting zone, which is essential in blind holes to prevent chip accumulation that can break taps or produce poor threads. With 3 flutes and a 12mm threading length, this tap handles most M8 applications.

Manufactured from High Speed Steel Cobalt with steam tempering, this tap maintains sharp cutting edges whilst working through steel and cast steel materials. The coating improves cutting fluid retention, reducing friction and heat build-up for smoother operation and extended tool life. The cylindrical shank with square drive provides secure mounting in tap wrenches or machine holders for accurate, controlled threading.

• M8 thread size extremely popular in automotive and general engineering
• 3-flute spiral design for efficient chip evacuation in blind holes
• 12mm threading length accommodates most M8 applications
