Description of πŸ”§ Polished MMO5 32 4FSE Drill America

Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Available in polished finish. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. 4 Flute single end.

Very disappointed with this end mill

Very disappointed with this end mill. I was engraving on a flat sheet of 6061 aluminum and it broke after about 7 minutes of starting work. I didn't think I was going very fast, the spindle was running at 10,000 rpm, 14 ipm feed and 0.002 documents. For some reason it just came out. I used lube and air to get the tiny shavings off, but it still broke.

Pros
  • High marks for grip and durability from testers
Cons
  • Not as thick as other alternatives

Just the right size for Category 5 with rubber stopper

It's hard to find a 3/16" end mill with a long cut or a shank the same diameter as the cutting face. That fits the bill. We have a selection of these for cutting round holes through rubber stoppers about 1 inch thick. Regular drill bits aren't designed to cut through the sidewalls of the rubber, so they just push it aside leaving a very rough cut. End mills work much better and this one is perfect for small 3/16" holes.

Pros
  • Dope πŸ”₯
Cons
  • Expensive

Ideal for milling FR1 circuit boards.

Wow, who knew what a difference you could make just by changing out an end mill. I have always used the ones supplied by The Other Machine Co with my OtherMill and just assumed deburring the plate with steel wool after cutting was a necessary step. Although this bit was expensive compared to others, I ordered it from Revain simply because it would come quicker. I put it in the machine and cut my first board and was surprised to find NO BAR. Copper edges are perfect. This photo shows the panel…

Pros
  • One year trial
Cons
  • Available in white only
