Cleveland C55421 Spiral Point Tap M12x1.75 HSS TiCN 3 Flute

SKU CH-FPCV-8JJJ3

M12x1.75 spiral-point tap cuts metric threads in through-holes with three-flute HSS-E TiCN coating for longer life

  • M12x1.75 metric thread cuts clean holes
  • Spiral point pushes chips forward for smoother tapping
  • TiCN coating resists wear on high-speed steel
  • Three flutes balance strength and chip clearance
  • 72 mm overall length reaches deep threads

Cleveland C55421 Spiral Point Tap M12x1.75

This Cleveland C55421 is a spiral point tap designed for creating M12x1.75 metric threads in through-hole applications. It suits machinists and maintenance technicians who need reliable thread production in general-purpose materials using machine tapping operations.

Plug chamfer HSS TiCN 3 flute through-hole

The plug chamfer engages the workpiece gradually to start threads cleanly in through holes. High-speed steel construction with TiCN coating resists wear and heat during repeated passes. Three flutes provide chip evacuation forward through the hole while the 42.07 mm thread length and 85.72 mm overall length fit standard tool holders.

Replaces worn uncoated taps in metric M12

This tap upgrades from uncoated high-speed steel tools when longer service life and reduced friction are required. The D6 thread limit and 6H class of fit match standard metric tolerance needs. It is not suited for blind-hole work where chips must be pulled upward or for left-hand thread requirements.

Questions about this item

What thread limit does the M12x1.75 tap reach before it binds in deep holes?

The tap is manufactured to a D6 limit for a 6H class of fit, so the pitch diameter tolerance is the first constraint you hit when tapping to full depth.

How much heat builds up in the HSS body during a full day of production tapping?

High-speed steel with TiCN coating dissipates heat well, but continuous cutting in steel will still raise the tool temperature enough to require cutting fluid or air blast for cooling.

What shank size must my tap holder or wrench accept for this 85.72 mm tap?

The M12 metric shank follows standard DIN dimensions, so any tap holder or adjustable wrench sized for M12 will grip it securely.
