Cleveland Golf 1/2 in 4-flute double-end square center-cutting cobalt end mill

Cobalt 4-Flute Double-End End Mill

This Cleveland Golf end mill is a general-purpose cutting tool made from cobalt steel for durability. The 1/2 inch diameter, double-end design provides two square, center-cutting edges in one tool. It suits machinists and fabricators who need reliable plunge cutting, peripheral milling, deep slotting and pocketing performance on a range of materials.

Thermals Noise and Power Draw

Cobalt steel construction resists heat buildup during extended cutting cycles, helping maintain edge integrity at higher feeds and speeds. The bright finish reduces friction without coating-related thermal insulation. As a solid rotary cutter, it produces no electrical noise or power draw; operational sound and heat depend entirely on the spindle, workpiece material and machining parameters used.

Upgrade Path and When It Is Worth It

This tool replaces single-end end mills when twice the cutting edges per holder change reduce downtime. The jump is worth it for shops running repetitive plunge, slot or pocket operations where tool-change frequency bottlenecks throughput. It is not for buyers who need longer reach beyond the 1 inch length of cut, larger diameters, or specialised geometries such as ball-nose or corner-radius profiles.
