Cleveland C33721 Double End Mill
The Cleveland C33721 is a 2-flute high-speed steel square end mill with a TiCN coating. It features a 0.75 inch milling diameter and a matching 3/4 inch shank with a Weldon flat. The tool measures 5 5/8 inches overall with a 1.3125 inch length of cut. This cutter suits general-purpose slotting and profiling in ferrous materials.
High-speed steel limits in abrasive alloys
High-speed steel offers toughness but wears faster than carbide in hardened steels or high-silicon aluminium. The TiCN coating extends life in moderate-heat cuts yet cannot prevent edge breakdown at very high surface speeds. Coolant supply is external only, so chip evacuation in deep pockets relies on flute geometry and operator technique.
Replaces single-end HSS cutters for cost savings
A double-end mill provides two cutting ends per holder, reducing tool-change downtime and per-edge cost compared with single-end equivalents. The jump is worthwhile when machining softer steels or non-ferrous parts where HSS toughness prevents chipping. It is not for production runs in hardened tool steels where carbide tooling maintains tolerance longer.

Questions about this item
Should I choose the .75 in diameter end mill or a different size for my milling task?
Select the .75 in diameter when your operation requires that specific milling width; the 3/4 in shank matches standard holders for this size.
What does the 1.3125 in length of cut mean for actual milling depth?
You can plunge or profile up to 1.3125 in deep in a single pass before the shank or holder contacts the workpiece.
How does the Weldon flat shank interface affect tool holding and runout?
The Weldon flat locks into a set-screw holder, preventing pull-out but typically allowing more runout than a precision collet or shrink-fit system.
