HP416-7874 Carbide End Mill
The OSG HP416-7874 is a carbide ball end mill with a 20 mm milling diameter. It features a TiAlN coating for wear resistance during machining operations. This cutting tool is designed for precision milling tasks in metalworking applications. The tool suits machinists and fabricators requiring accurate contouring capabilities.
Thermals noise and power draw
As a passive rotary cutting tool, this end mill generates no operational noise or electrical power draw. Heat generation depends entirely on the spindle speed, feed rate, and workpiece material selected by the operator. Proper coolant application manages thermal buildup at the cutting interface effectively. The TiAlN coating helps dissipate heat away from the cutting edges.
Build fit and system needs
This non-coolant-through end mill requires a tool holder compatible with its shank dimensions for secure mounting. The 38.00 mm cut length determines the maximum depth of cut achievable in a single pass. It frees up internal tool clearance by eliminating the need for through-spindle coolant plumbing. The tool integrates directly into standard milling machine setups without additional adapters.

Questions about this item
How do I mount the 20 mm shank of the OSG HP416-7874 end mill, and what step do people often skip?
Clamp the 20 mm shank in a matching collet or hydraulic holder, then tighten to the holder’s rated torque — skipping the torque check is the common mistake that leads to run-out.
What maintenance or replacement will the TiAlN-coated carbide cutter need later?
The TiAlN coating wears gradually; plan to re-sharpen or replace the tool once flank wear reaches your shop’s limit, typically after the coating is visibly depleted.
What limit appears first on the 38.00 mm flute length during a long profiling pass?
Deflection increases with the 38.00 mm flute length, so chatter or dimensional drift usually shows up before the carbide itself fails.
