Dormer E650 Metric Spiral Flute Tap & Drill

The Dormer E650 M4 Spiral Flute Tap & Drill drills and taps an M4 metric coarse thread in a single pass, streamlining what is traditionally a two-step process. The M4 thread size is frequently used in electronics enclosures, automotive components, precision instruments, and light fabrication work — a versatile choice for both professional engineers and DIY enthusiasts working on detailed assemblies.

Compatible with a hand-held power tool, the M4 E650 eliminates the need for a tap wrench or tool change, keeping the workflow efficient and reducing the time spent on each threaded hole.

The steam tempered surface coating helps retain cutting lubricant, resulting in a cleaner thread finish and smoother operation in steel and cast steel.
