Dormer E003 HSS-E High Perf Mult-App Metric Coarse Spiral Flute Tap M4 Spiral Flute

The Dormer E003 M4 Spiral Flute Tap is designed for creating M4 metric coarse threads in blind holes, a popular small thread size used extensively in electronics, control panels, light engineering, and small mechanical assemblies. This versatile tap is suitable for both professional precision work and DIY projects requiring accurate small threads. M4 threads are one of the most commonly encountered small thread sizes, frequently specified in electrical enclosures, instrument housings, light brackets, small machinery, and computer equipment. The spiral flute configuration efficiently removes chips upward from blind holes, which is crucial for preventing the tap breakage that can easily occur at smaller diameters if chips accumulate. With 3 flutes and a 7mm threading length, this tap covers most M4 applications. The High Speed Steel Cobalt construction ensures the tap maintains sharp cutting edges for producing clean, precise threads in steel and cast steel materials. The steam tempered
