Cleveland C39048 double-end mill
The Cleveland C39048 is a square double-end mill designed for general-purpose milling in steel and other ferrous materials. It suits machinists and maintenance technicians who need a replaceable cutter with two usable ends. The 2-flute high-speed steel body provides a balance of chip clearance and edge strength for slotting and profiling operations. This tool is not for buyers who require coolant-through capability or a larger shank diameter for heavy hogging cuts.
High-speed steel with TiN coating
The TiN coating on the high-speed steel substrate reduces friction and improves wear resistance during dry machining. Cutting temperatures stay lower than with uncoated HSS, which helps maintain edge integrity in normal use. Power draw on the spindle remains moderate because the 2-flute geometry limits chip load per revolution. The tool produces typical HSS noise levels without vibration-dampening features.
Weldon flat and double-ended utility
The Weldon flat on the 3/8 in shank allows secure clamping in standard end-mill holders without a collet. Having two cutting ends on one tool body lets the operator flip the mill when the first end wears, extending productive time between tool changes. The 0.375 in length of cut and 0.25 in milling diameter define the reach and width of each pass. No additional accessories or software are bundled with this cutter.

Questions about this item
How do I install the Cleveland C39048 end mill in a Weldon holder, and what step is often missed?
Insert the 3/8 in shank until the Weldon flat seats against the set screw, then tighten the screw firmly on the flat; the step often missed is verifying the flat is fully engaged before locking.
What maintenance or replacement will the TiN-coated HSS cutter need later?
The TiN coating reduces wear, but the high-speed steel flutes will dull over time; plan to resharpen or replace the cutter when cutting edges show rounding or chatter increases.
What limit appears first during sustained cutting with the 0.25 in diameter and 0.375 in length of cut?
Heat buildup in the non-coolant-through tool body typically limits sustained feed rates before deflection becomes an issue on this short flute length.
