Cleveland Golf Cobalt 3/16 2FL Double End Mill

Cobalt Double-End Mill for Finishing

The Cleveland Golf Cobalt 3/16 2FL Double End Mill is a general-purpose cutting tool made from cobalt steel for wear resistance. It features a square-end profile on both ends with two right-hand flutes and a 30-degree helix angle. The bright, uncoated finish suits conventional milling setups. Machinists performing light finishing passes in ferrous or non-ferrous materials will find it suitable.

Thermals, Noise and Power in Normal Use

As a solid rotary cutter, the tool generates heat only through friction at the cutting interface during operation. It has no motor, electronics or moving parts of its own, so it produces no audible noise and draws no electrical power. Workpiece temperature depends entirely on spindle speed, feed rate, coolant use and material being machined.

Behaviour Under Sustained Load

Cobalt substrate retains hardness at elevated temperatures better than standard high-speed steel, allowing longer engagement before edge degradation. The double-ended design provides a fresh cutting end when the first wears, effectively doubling usable life in repetitive finishing tasks. Chip evacuation relies on the two-flute geometry and machine coolant strategy rather than internal channels. Builders needing internal coolant feed or more flutes for heavy roughing should select a different tool.
