Dormer E650 Metric Spiral Flute Tap & Drill

The Dormer E650 Metric Spiral Flute Tap & Drill is a precision-engineered combination tool that drills a core hole and cuts a thread in a single pass — saving significant time and effort on site or in the workshop. Designed to work directly with a hand-held power tool, there is no need for a separate tap wrench or tool change, making the threading process faster and more straightforward for both professional tradespeople and capable DIY enthusiasts.

Manufactured from High Speed Steel to Dormer's ISO standard, the tool features a steam tempered surface coating that retains lubricant and promotes smoother, cleaner cutting. The 2-flute spiral design cuts metric coarse right-hand threads through-hole, with primary application in steel and cast steel.

Available in sizes from M3 to M16, there is a variant to suit a wide range of threading tasks.
