Cleveland C42518 Square End Mill PM-4 2in Cut

This Cleveland C42518 is a square end mill built from powdered metal with an uncoated finish. It suits machinists and maintenance teams who need a general-purpose milling cutter for slotting, profiling or plunge cuts in steel and other ferrous materials. The Weldon flat on the shank provides a secure grip in standard end-mill holders.

Practical limits of the Weldon shank interface

The 1-inch shank diameter restricts use to holders and collets that accept that exact size, so smaller tooling systems cannot clamp this cutter. An overall length of 4-1/2 inches with a 2-inch length of cut limits reach in deep cavities or through long overhangs. The uncoated powdered-metal substrate wears faster than coated carbide when run at high speeds or in abrasive alloys.

Questions about this item

Which end mill diameter should I choose for this Cleveland C42518?

The Cleveland C42518 is supplied with a 1 in milling diameter, so there is no alternative diameter to select for this specific model.

How does the 2 in length of cut perform in a milling machine?

The 2 in length of cut allows deep pocketing and profiling passes in a single engagement, reducing the number of step-downs needed for thicker workpieces.
