Cleveland M18x2.5 Straight Flute Tap

This Cleveland C54835 straight flute hand tap cuts internal M18 threads with a 2.5 mm pitch. It is made from high speed steel with a bright uncoated finish for general-purpose threading in ferrous and non-ferrous materials. The D7 thread limit targets a 6H class of fit.

Hand tapping constraints and drill size

A 15.50 mm drill produces the recommended 75 percent thread depth before tapping. The 46.04 mm thread length and 102.39 mm overall length define the reach in through or blind holes. Chip evacuation relies on manual reversal because the straight flute design has no spiral to pull swarf clear.

Upgrading from worn or smaller taps

This tap replaces dull or damaged M18x2.5 tooling to restore thread accuracy without changing drill size. The jump is worth it when existing taps no longer hold the 6H tolerance or when a bright high speed steel finish is preferred over coated alternatives for specific materials.

Questions about this item

Should I choose the M18x2.5 tap or a different thread size?

This tap cuts M18 threads with a 2.5 mm pitch; select it only when the hole and fastener call for that exact metric size.

What does the 46.04 mm thread length mean when I use the tap in a machine?

The 46.04 mm thread length is the cutting portion; it determines how deep a full-form thread can be produced in one pass.

What does the D7 thread limit cap in practice?

The D7 limit sets the maximum pitch-diameter tolerance for a 6H class of fit, controlling how tight or loose the finished thread will be.
