Dormer E557 HSS Spiral Flute Tap

This M10 spiral flute tap with 1.5mm pitch is an ideal mid-range size for general engineering and maintenance applications. Whether you're working on automotive repairs, machinery maintenance, or fabrication projects, this tap delivers reliable threading performance in blind holes where chip evacuation is critical.

The 10mm connection diameter and 80mm overall length provide excellent control and reach for a wide variety of threading tasks. The spiral flute design pulls chips up and away from the cutting zone, making it particularly effective for power tool use where continuous chip removal is essential for thread quality.

Perfectly suited for steel and cast steel materials commonly found in both professional workshops and home garages, this tap combines durability with precision performance.

Features and Benefits:
• HSS construction withstands the demands of power tool operation
• Three-flute spiral design prevents chip packing in blind holes
• Metric coarse thread form for standard M10 applications
