Cleveland Golf

Cleveland Golf 3/16" Cobalt End Mill 4FL Double End TiCN

SKU CH-TSTQ-BBTT4

A 4-flute cobalt end mill with TiCN coating, double-ended design and 30-degree helix for general-purpose finishing

  • Product typeHole, Drill, Bore & Wire Gauges
  • Cobalt construction resists wear for longer tool life
  • TiCN coating reduces friction and heat during cutting
  • Four flutes give smooth finish on ferrous materials
  • Double-end design provides two cutting ends per tool
  • 30-degree helix angle promotes stable chip evacuation

Cobalt End Mill 3/16" TiCN Finish

This double-end square mill is made from cobalt steel with a TiCN coating for general-purpose finishing. It suits machinists who need a right-hand cutting tool with a 30-degree helix angle for standard milling operations.

For finishing passes in slotting or profiling

Shops running heavy roughing cuts or needing chip-breaking geometry should look at roughing end mills instead. Buyers who require a corner radius for fillet work or a different shank diameter for their holder will need another tool.

4-flute double-end design with 7/16" cut length

The four flutes on both ends provide two usable cutting surfaces per tool, effectively doubling tool life for finishing tasks. A 3/8" shank fits standard collets and holders for rigid setups.

Questions about this item

How do I install the 3/8 in. shank end mill in my tool holder without damaging the TiCN coating?

Clamp the 3/8 in. shank securely in a collet or end-mill holder, ensuring the 7/16 in. length of cut clears the workpiece. Avoid over-tightening set screws directly on the coated shank to prevent TiCN damage.

When will the TiCN finish on the 4-flute cobalt end mill need replacement?

Replace the tool when the TiCN coating wears off the cutting edges, causing increased heat or poor finish on the workpiece. Cobalt substrate resists wear, but the 30-degree helix and .000 corner radius will eventually dull under finishing cuts.

What is the first limit reached during sustained finishing cuts with the 3/16 in. diameter tool?

The 3/16 in. diameter and 3-1/8 in. overall length limit rigidity first, causing deflection or chatter before the cobalt substrate overheats. The 4-flute design and right-hand helix evacuate chips, but the small diameter restricts deep sustained cuts.
