M10×1.25 Spiral Point Tap
The Cleveland C57187 is a high-speed steel tap designed to cut M10 metric threads with a 1.25 mm pitch. Its spiral point geometry pushes chips ahead of the cut, making it suited for through-hole work on milling machines or rigid tapping heads. The bright, uncoated finish is standard for general-purpose ferrous and non-ferrous materials. Three flutes provide a balance of chip space and core strength for consistent thread quality.
Upgrade from Hand Taps
This machine tap replaces general-purpose hand taps when a shop moves from manual threading to CNC or power-driven operations. The D5 thread limit and 6H class of fit deliver tighter tolerance control than standard H-limit hand taps, reducing scrap on batch runs. The jump is worth it when cycle time and repeatability matter more than the lower upfront cost of carbon-steel hand tools. It requires a 0.3438 in drill for 75 percent thread engagement.
Sustained Production Behaviour
Under continuous machine use the high-speed steel body resists tempering better than carbon alternatives, holding cutting geometry through repeated holes. The spiral point ejects chips forward, preventing flute packing that can stall a tap in deep through-holes. With a 31.75 mm thread length and 74.61 mm overall length, it reaches standard depths without extension. Uncooked bright finish demands proper lubrication to avoid galling during long shifts.

Questions about this item
What drill size do I need for the M10x1.25 thread?
Use a 0.3438 in drill for a 75 percent thread engagement with this tap.
How do I start the tap straight in the hole?
Apply steady axial pressure while turning the spiral point tap clockwise to prevent cross-threading.
When should I replace this high-speed steel tap?
Replace it when the cutting edges dull and thread quality degrades in the M10x1.25 size.
