  • Cuts stainless steel and titanium up to 55 HrC
  • Cobalt substrate handles high-tensile steels 40-55 HrC

Cobalt End Mill 1/4 in 4 Flute

The Cleveland Cobalt end mill has a 1/4 in. cutting diameter with a 3/8 in. shank and four flutes. Its TiCN coating resists wear on cobalt, nickel, austenitic alloys, high tensile steels from 40 to 55 HrC, stainless steel and titanium alloys. The square, single-end design is centre-cutting for plunging and peripheral milling.

TiCN Coating Limits

TiCN improves heat resistance and lubricity but it is not suited for every material. The tool is specified for the alloy groups listed above and may wear faster on abrasive composites or very soft, gummy metals. Coolant choice and spindle rigidity also affect whether the coating reaches its expected life.

Installation and Common Issues

Clamp the 3/8 in. shank securely in a matching collet or end-mill holder to prevent pull-out under load. Run the right-hand helix at the correct speed and feed for the target hardness; excessive speed burns the coating while too low a feed causes rubbing. Verify the 5/8 in. length of cut clears the workpiece without bottoming out the 2-7/16 in. overall length.

Questions about this item

Which end mill diameter matches a 1/4 in. cutting requirement?

The 1/4 in. diameter with a 5/8 in. length of cut and 2-7/16 in. overall length fits that specification.

What hardness range does the TiCN coating handle in peripheral cuts?

The tool targets cobalt, nickel, austenitic alloys and high tensile steels from 40 to 55 HrC plus stainless and titanium alloys.

How does the 30 degree helix angle affect chip evacuation in these materials?

The 30 degree helix on four flutes balances chip removal and edge strength for the listed alloys.
