Carmex Threading Taps

Carmex's Supercut range covers three tap constructions across four thread systems. Spiral point taps push the chip forward, ahead of the tap, so they're the right choice for through-holes where the swarf can just fall out the other side. Spiral flute taps pull the chip back up and out of the hole, which is what you need for a blind hole where there's nowhere for the chip to go but back the way it came.

Forming taps, also called roll taps, don't cut a chip at all. They squeeze the thread into shape by displacing material rather than cutting it away, which leaves no swarf and produces a stronger thread in ductile materials. All three constructions are stocked in Metric, BSP, UNC and UNF, in both HSS-E and Powder Metal.

Powder Metal is the harder, more wear-resistant option for tougher or more abrasive materials; HSS-E covers general-purpose steel and stainless work. All held in UK stock. Order before 4pm and it ships same day.
