Cleveland 42052 End Mill Overview

The Cleveland 42052 is a 2-flute high-speed steel square double end mill designed for general milling tasks. It features a 0.15625 inch milling diameter and a 3/8 inch shank diameter with a Weldon flat. This uncoated tool suits machinists and fabricators needing a versatile cutter for slotting or profiling operations.

Sustained Load Behaviour

Under continuous cutting the uncoated high-speed steel body generates heat that must be managed with appropriate coolant or air blast. The 0.4375 inch length of cut allows moderate depth passes but extended heavy profiling will accelerate flank wear. Operators should monitor chip evacuation to prevent recutting and premature edge degradation.

Setup Checks Before Ordering

Verify that your tool holder accepts a 3/8 inch Weldon flat shank for secure clamping. Confirm the machine spindle can reach suitable speeds for the 0.15625 inch diameter in your workpiece material. Ensure your work envelope accommodates the 3 1/8 inch overall length without interference from fixtures or workpiece geometry.

Questions about this item

How much heat does the 0.15625 in end mill generate during continuous cutting?

High-speed steel dissipates heat well at moderate speeds, and the uncoated surface avoids coating breakdown that can trap heat in prolonged use.

What holder or machine interface is required for the 3/8 in Weldon flat shank?

A standard Weldon-compatible end-mill holder with a set-screw locking flat is needed; the 3/8 in shank fits common milling-machine tooling.

Will the 3/8 in shank fit the collets on my older Bridgeport mill?

Yes, the 3/8 in Weldon flat shank matches the standard tooling used on many vintage knee mills including Bridgeport models.
