Cleveland M12x1.75 Spiral Point Tap
The Cleveland C55365 is a metric spiral point tap designed for creating M12 threads with a 1.75 mm pitch. It suits machinists and maintenance technicians who need reliable internal threading in through-hole applications. The right-hand cut and plug chamfer support efficient chip evacuation forward through the hole.
High-speed steel construction with TiN coating
The tap is manufactured from high-speed steel and features a titanium nitride coating that reduces friction and extends tool life during repetitive use. Three flutes provide balanced chip clearance while maintaining core strength. The 85.72 mm overall length and 42.07 mm thread length fit standard tapping holders and allow adequate reach for typical workpiece thicknesses.
Replaces worn or undersized M12 taps
This D6 limit tap produces a 6H class of fit, making it a direct replacement for general-purpose M12x1.75 tooling that has dulled or was ground to a tighter tolerance. The 75 percent thread drill size of 10.30 mm guides drill selection for proper thread engagement. The jump is worth it when thread quality or tool longevity becomes inconsistent with uncoated alternatives.
