Cleveland Cobalt End Mill 3/16

This double-ended square end mill is made from cobalt steel for general-purpose finishing tasks. The TiCN coating adds wear resistance and extends tool life in production environments. It suits machinists and maintenance shops that need a reliable cutter for slotting, profiling, and light finishing passes on ferrous and non-ferrous materials. Buyers who need roughing geometry or larger diameters should look elsewhere.

Installation and common issues

The 3/8 in. shank fits standard ER collets, Weldon flats, and mill holders without adapters. Right-hand helix and center-cutting design allow plunging and side milling in a single setup. Vibration often appears when the stick-out exceeds the 7/16 in. length of cut, so keep the tool short in the holder. Incorrect feed rates or insufficient coolant cause premature flank wear on the 30 degree helix flutes.

Practical limits of the interface

The fractional 3/16 in. diameter and 3-1/4 in. overall length restrict reach in deep cavities or tall features. Two flutes limit chip evacuation in full-width slots compared to three- or four-flute designs. The .000 in. corner radius leaves a sharp internal corner that may require a secondary operation for fillet specs. TiCN performs best in moderate-speed finishing; it is not optimised for high-temperature alloys or heavy roughing cuts.

Questions about this item

How do I verify the 3/16" end mill is cutting correctly after installation?

Check for a smooth finish and the specified 30-degree helix engagement in the workpiece. The right-hand cutting direction should produce clean chips without chatter when the tool runs true in the holder.

What comes with the double-end cobalt mill and what must I supply?

The box contains the TiCN-coated 3/16" diameter tool with two square ends, 7/16" length of cut, and 3/8" shank. You must provide a compatible 3/8" tool holder and coolant or lubrication for the application.

When should I choose this 2-flute cobalt version over other end mills?

Select this general-purpose finishing mill for slotting or profiling in steel and alloy materials where the 3/16" diameter, double-end economy, and TiCN wear resistance match the job requirements.
