Cobalt End Mill for Finishing

This Cleveland Golf cobalt end mill is built for general-purpose finishing work in a machine shop or maintenance department. The double-ended design gives two cutting ends per tool, reducing change-over time when one end wears. Bright uncoated finish suits a range of ferrous and non-ferrous materials.

30-degree helix with four flutes

A 30-degree helix angle combined with four flutes provides the chip evacuation and surface finish control needed for finishing passes. The right-hand cutting direction and zero corner radius produce a true square profile in the workpiece. Cobalt substrate resists heat during extended cuts.

Double-ended 3/8-inch shank

The 3/8-inch shank fits standard tool holders and the double-ended layout effectively doubles tool life before replacement. Bright finish means no coating to wear off or contaminate sensitive alloys. Restricted from sale in certain states, so verify local compliance before ordering.

Questions about this item

What does the 30-degree helix angle mean when the end mill is cutting in a machine?

A 30-degree helix provides a balance of chip evacuation and edge strength for general-purpose finishing in a variety of materials.

How does the 3/8-inch shank diameter determine what tool holders can be used?

The 3/8-inch shank fits standard collets and end mill holders sized for that diameter, ensuring secure clamping in the spindle.

What clearance is needed for the 3-3/8-inch overall length and 5/8-inch length of cut?

The 3-3/8-inch overall length requires sufficient Z-axis travel and tool changer clearance, while the 5/8-inch flute length sets the maximum depth per pass.
