Cleveland Spiral Point Tap M4x0.7
The Cleveland C55361 is a high-speed steel spiral point tap designed for creating M4x0.7 metric threads. It suits maintenance technicians and metalworkers who need reliable through-hole threading in general-purpose applications. The TiN coating enhances wear resistance during repetitive use.
Upgrading from worn or uncooled taps
This tap replaces dull or uncoated tooling that produces rough threads or fails prematurely in steel. The jump is worth it when thread quality must meet a 6H class of fit and a 75 percent thread depth with a 3.30 mm drill size. The D4 thread limit ensures consistent pitch diameter control for production runs.
Limits of the spiral point design
The spiral point geometry pushes chips ahead of the tap, so it is restricted to through-hole work where chips can escape. It cannot be used for blind holes where chip evacuation is blocked. The 9.65 mm thread length and 54.1 mm overall length define the maximum reach for this specific tool.

Questions about this item
What drill size matches the 75 percent thread specification for this M4x0.7 tap?
The recommended drill size is 3.30 mm for a 75 percent thread engagement with the M4x0.7 thread form.
How do I start the tap straight in the hole using the spiral point design?
Align the tap perpendicular to the workpiece, apply steady forward pressure while turning clockwise, and let the spiral point push chips ahead without reversing until depth is reached.
When should I replace this High Speed Steel TiN coated tap?
Replace the tap when cutting edges show visible wear, thread quality degrades, or torque increases noticeably during use on similar materials.
