Drilling with end mills? - CNCzone.com
Sep 10, 2014· End mills are typically used for horizontal carving and cut laterally. Additionally, most mills are "center-cutting," meaning they are able to cut both axially and laterally. This is due to cutting flutes that extend to — and protrude from — the end face and enable plunge cutting.

Plunge Milling - Great for Roughing & Slotting! WW205 ...
Plunge milling works much like drilling: plunge straight in, withdraw, step over plunge again, and so on. Since all the cutting force vectors are right up the tool's strong centerline, you can safely feed faster by plunging along the Z axis than by end-milling along the X and Y axes.

Long-Reach End Mills | McMaster-Carr
Made of solid carbide, the end mills in these sets are harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a square end for milling square slots, pockets, and edges.

Plunge, ramping and cutting feed rate problem - Autodesk ...
Typically I plunge at 1500 to 2000mm/min. If I'm using a 3mm end mill and cutting 8mm deep at 350mm/min but my first 1.5mm of cut is at 1500 to 2000mm/min. No wonder I'm breaking tools. I suggest changing the transition point of plunge/ramp feed rate to cutting feed rate to be the perimeter of the tool and not the center of the tool.
