Cleveland C39619 Double End Mill
The Cleveland C39619 is a 3-flute high-speed steel square end mill designed for centre-cutting milling tasks. It serves machinists and maintenance teams who need a double-ended tool for slotting and profiling operations.
Practical Limits of HSS and TiCN
High-speed steel with TiCN coating handles general-purpose ferrous and non-ferrous materials but wears faster than carbide in abrasive or high-heat cuts. The 0.1875 in diameter and .5 in length of cut restrict use to shallow features and light chip loads.
Installation Notes
The 3/8 in shank with a Weldon flat locks into a standard side-lock holder using a set screw. Ensure the flat seats fully to prevent pull-out. Vibration often signals excessive stick-out or insufficient clamping force.

Questions about this item
What does the 0.1875 in milling diameter mean for slot width?
The cutter produces a slot 0.1875 in wide in a single pass, matching the stated milling diameter.
How does the 3/8 in shank diameter affect tool-holder choice?
A 3/8 in shank fits standard Weldon-flat holders and collets sized for that diameter.
What does the TiCN coating do during cutting?
TiCN increases surface hardness and heat resistance, extending tool life in steel and stainless.
