Cleveland C40009 Roughing End Mill
The Cleveland C40009 is a 3-flute PM+ HSS-E square roughing end mill designed for aggressive material removal in milling operations. It features a 1 inch milling diameter and a 2 inch length of cut for deep pocketing and profiling tasks. The tool suits machinists and fabrication shops requiring high metal removal rates on ferrous alloys. Its Weldon flat shank ensures secure clamping in standard tool holders.
Sustained Load Performance
The powdered metal HSS-E substrate provides enhanced wear resistance and toughness compared to conventional high-speed steel during extended cuts. Three flutes balance chip evacuation with core strength, reducing vibration when the full 2 inch length of cut is engaged. The uncoated surface avoids coating delamination risks in abrasive or high-temperature alloys. This geometry maintains consistent chip formation under heavy radial engagement.
Thermals Noise Power
Uncoated HSS-E construction tolerates elevated cutting temperatures without the thermal shock sensitivity of coated carbides. The tool generates typical machining noise levels for roughing operations in steel and stainless materials. Power consumption at the spindle depends on the machine tool drive and the specific workpiece material hardness. No active cooling is integrated; flood or mist coolant is managed externally by the machine setup.

Questions about this item
How much heat and power draw should I expect from the C40009 during a full day of roughing cuts?
The tool itself generates no heat or power draw; all thermal load and energy use come from the spindle and machine tool driving it.
What holder or machine interface is required to run the C40009?
A 1 in Weldon flat holder on a milling machine with a matching spindle taper is needed to secure the shank.
Will the C40009 work with the older Bridgeport I keep in the shop?
Yes, if the Bridgeport accepts a 1 in Weldon shank and can provide the rpm and feed rates suited to powdered-metal HSS-E roughing.
