Cleveland C27670 M8-1.25 Semi-Bottoming Tap
The Cleveland C27670 is a straight-flute tap designed to cut M8 threads with a 1.25 mm pitch. It is made from cobalt with a black oxide and nitride surface treatment for wear resistance. The semi-bottoming chamfer allows threading close to the bottom of a blind hole. This accessory suits machinists and maintenance technicians who need a reliable metric threading tool.
Suited for through and blind holes in general
The semi-bottoming design and straight flutes make this tap effective for both through-holes and blind holes where chip evacuation is manageable. It matches a 6H class of fit with a D5 thread limit using a 75 percent thread drill size H. Builders who require a spiral-point or spiral-flute geometry for deep blind holes in sticky alloys should consider a different flute style.
M8x1.25 thread size with 17.46 mm thread length
The tap cuts a standard M8x1.25 metric thread over a 17.46 mm thread length within an overall length of 69.06 mm. This specific thread size and thread length determine whether the tool fits the hole depth and fastener specification required for the job. Verify the workpiece material and hole depth against these dimensions before ordering.
