Dormer E003 HSS-E High Perf Mult-App Metric Coarse Spiral Flute Tap - M3

The Dormer E003 M3 Spiral Flute Tap is perfect for creating M3 metric coarse threads in blind holes, a small thread size commonly required in precision engineering, electronics enclosures, instrumentation, and small mechanical assemblies. This fine tap is ideal for both professional workshops and hobbyists working on detailed projects requiring precise small threads. M3 threads are frequently specified in control panels, small motor housings, precision instruments, computer hardware, and delicate mechanical assemblies where space is limited. The spiral flute design is essential even at this small diameter, as chips must be evacuated upward from blind holes to prevent thread damage and tap breakage. With 3 flutes and a 6mm threading length, this tap handles most M3 applications in thin materials and shallow holes. Manufactured from High Speed Steel Cobalt with steam tempering, this tap maintains sharp cutting edges essential for producing clean, accurate threads at small diameters. The coating helps retain cutting fluid, which is particularly important for small taps that can break easily if cutting becomes too forceful. The cylindrical shank with square drive provides secure mounting in precision tap wrenches.
