Cleveland C61083 2-Flute Carbide Square Single End GP End Mill

Cleveland C61083 2-Flute Carbide End Mill

This square-end milling cutter is made from solid carbide for general-purpose machining. It suits CNC operators and tool-room staff who need a durable, uncoated tool for slotting and profiling in a range of ferrous and non-ferrous materials. The straight shank fits standard holders.

Practical limits of the uncoated carbide interface

Without a coating the tool relies on the base substrate for wear resistance, so heat build-up limits speed in abrasive or high-alloy steels. Chip evacuation depends entirely on the two-flute geometry and external coolant because there is no through-coolant passage. The 1 in diameter and 3 in length of cut define the maximum radial and axial engagement.

Upgrades from high-speed steel or coated cutters

Replacing a high-speed steel end mill with this carbide version raises cutting speeds and extends tool life in easier materials. The jump is worth it when the job allows uncoated carbide speeds and does not demand the extra lubricity or heat barrier of a coated flute. It does not suit operations that require through-spindle coolant or specialised geometries.
