Cleveland M10 × 1.5 Spiral-Point Tap
The Cleveland C57189 is a high-speed steel spiral-point tap cut for M10 × 1.5 metric threads. It has an overall length of 74.61 mm and a 31.75 mm thread length with three flutes. The bright uncoated finish suits general-purpose threading in through holes. Right-hand threads follow standard rotation.
For through-hole threading in steel or cast iron
This tap matches a 6H class of fit and a D6 thread limit, requiring a 75 percent thread drill size of 8.50 mm. It is not for blind holes where chip evacuation needs a spiral-flute design, nor for left-hand thread requirements. Buyers who need coated tool life or different tolerance classes should look at other options.
M10 × 1.5 thread size with D6 limit
The single specification that decides fit is the M10 × 1.5 thread size combined with the D6 thread limit and 6H class of fit. Verify the workpiece material and hole type against these limits before ordering.

Questions about this item
How do I install the M10x1.5 spiral point tap and what step is often missed?
Use an 8.50 mm drill for the 75 percent thread hole, then run the tap right-hand to the 31.75 mm thread length; the step often missed is clearing chips every few turns to prevent binding.
What maintenance or replacement will this high-speed steel tap need later?
The bright uncoated flutes will dull with use; resharpen or replace the tap once thread quality drops or cutting torque rises noticeably.
What limit appears first during sustained tapping with this D6 class 6H tool?
Chip evacuation in deep holes becomes the limiting factor as the 74.61 mm overall length fills with swarf, increasing torque and risk of breakage.
