Straight Flute Tap 1/4 -28 HSS MPN:305210

The TiN coating on these taps protects them from wear and allows them to be used at higher speeds than taps with a bright finish. Non-coolant-through taps do not have coolant holes, so a separate hose is required to bring coolant to the cutting area if it is needed.
