E557 Dormer Metric Spiral Flute Machine Taps - For General Use
HSS Spiral Flute Power Tool Tap, Metric, ISO Standard
Ideal for hand held tapping with the use of Power Tools. Tapping typically produce long stringy chips which, when not evacuated properly, can cause serious problems especially when threading blind holes. The spiral flute design counters this problem as it draws chips from the hole being tapped.
