When one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. Made of solid carbide, these end mills 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 …

End mill's cutting part is wrapped around flutes, which are a bunch of helical grooves on side of end mills. Each flute is with a sharp edge at least. While you can't see this kind of component on drill bits cause they merely use the edges on its top area instead of lateral cutting edge to drill down and evacuate chips.

The flat bottom holes are nothing critical, only clearance for a bolt head. I have been a machinist for over 30 years but this was on manual machines such as cincinnati verticals and g&L horizontal boring mills. On these machines I would put in 1 1/4" flat bottom holes using a 1 1/4" 2 flute high speed endmill and just plunge it right in.

For a flat bottom, just drill to size and clean up the bottom with any center cutting endmill - thats the easiest. Two flute center cutting can be plunged more easily than four flutes and if you have a dinky mill its hard to get an accurate sized hole making a plunge cut with an endmill. The spindle likes to walk around. Willy Senior Member

End mills are the cutting tools (also called router bits) that are inserted into the collet of a spindle or router. It is the part that spins and does all of the cutting in all directions. Some end mills can plunge into the material (like drilling). All end mills have …

Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. They have a square end for milling square slots, pockets, and edges.. End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with …

Todays carbide end mills that are center cutting - and with a little dish - (I think there is a 3-5 degree dish) - will plunge, but inefficient chip removal - the bottom of the hole will sorta look flat. With a HSS end mill that is not center cutting "might" plunge but smoke badly and leave a mess in the bottom of the hole.

End mills can have 2 to 5 or more flutes. For metal cutting 4 flute cutters are normally used.
