Cleveland C80550 5-Flute Carbide End Mill

This Cleveland C80550 is a 5-flute carbide end mill built for machining ferrous materials. It features a 0.375 inch milling diameter and a 0.02 inch corner radius for added strength. The tool is coated with TiAlN to resist heat and wear during heavy cutting. It suits CNC operators and machinists working on steel or iron components.

Practical limits of the 5-flute design

The five-flute geometry increases feed rates and finish quality in ferrous alloys but reduces chip space compared to fewer flutes. This makes deep slotting or wide radial cuts more difficult without proper coolant evacuation. The 1.125 inch length of cut restricts the maximum depth in a single pass. High-speed machining demands rigid tool holding to prevent vibration.

Check your holder and machine rigidity

Verify that your tool holder accepts a straight shank matching the cutter diameter. Ensure the spindle provides enough torque at the speeds required for TiAlN-coated carbide in steel. Confirm the machine has sufficient rigidity to handle the cutting forces generated by five flutes. Check that your coolant system can reach the cutting zone effectively.

Questions about this item

Should I choose the .375in diameter or the 1.125in length of cut for my milling job?

The .375in figure is the cutting diameter; the 1.125in figure is the length of cut. Pick the diameter that matches your required slot or hole size, and ensure the length of cut covers the depth you need to mill in one pass.

What does the .02in corner radius do when the tool is in the spindle?

The .02in corner radius leaves a small fillet at the bottom of each cut, reducing stress concentrations in the workpiece and strengthening the tool corners against chipping during heavy feeds in ferrous materials.

How does the TiAlN coating affect the tool's speed limit in practice?

TiAlN tolerates higher cutting temperatures than uncoated carbide, letting you run faster surface speeds and heavier chip loads in steel and iron before the coating oxidises and wears.
