Cleveland C39053 Double End Mill
The Cleveland C39053 is a 2-flute HSS square double end mill designed for general milling tasks. It suits machinists and maintenance teams needing a versatile cutter for slotting and profiling in various materials. The TiCN coating extends tool life compared to uncoated alternatives.
Weldon Flat Shank and TiCN Coating
A Weldon flat on the 3/8 in shank provides secure clamping in standard end mill holders, reducing slippage during heavy cuts. The TiCN coating increases surface hardness and heat resistance, allowing higher speeds in steel and cast iron. High-speed steel construction offers toughness for interrupted cuts.
Replaces Single End Mills for Cost Savings
This double end mill effectively provides two cutting tools in one body, reducing tooling cost per edge. The switch is worth it when operations use square end profiles and can utilise both ends before regrinding. It is not suited for applications requiring longer reach or specialised corner radii.

Questions about this item
What shank standard and diameter does the C39053 end mill use?
It has a 3/8 in Weldon flat shank, so it fits standard Weldon holders for that shank size.
What are the cutting and overall lengths that determine tool clearance?
Length of cut is 0.375 in and overall length is 2 7/8 in, setting the reach and holder engagement depth.
How is the double-end mill secured in the holder, and what step is often missed?
Tighten the set screw onto the Weldon flat; the common error is clamping on the round shank instead of the flat.
