I really wanted a 45 degree rake face mill but was very impressed by the 22 5 star reviews. You can't disagree with that, but I also think that with a relatively inexpensive tool you can argue that you might potentially be listening to a little less selective users. I first measured the tool on my measuring plate and one of the positions was significantly higher than the others. Before attempting this, I consulted "amateur mechanics" and was advised to try it. everything would be fine. Myβ¦
I use this in a J head bridgeport at work to size wear plates for injection molding tools such as materials like Ampco 18 and copper impregnated CRS, .250 gauge . "Up to .500" has absolutely no problem with it, I've also made a few 1" wide cuts (diameter of cutters) with it, cutting both P20 tool steel and CRS, and a .050" depth of cut. I run the tool at 1000 RPM for most cuts and 1200-1400 for the "finish" cuts. I recommend having a VERY hard attitude when using this tool because you shouldβ¦
Pro: I am very surprised by this cutter. On mild steel* I was able to cut 200 miles deep through a full 1/2 inch with my 1 HP Bridgeport with no problem. at 350 rpm. Cut only on a (low) plate. This single insert, which acts as the cutting edge, provides a good surface finish. If you were to use a power feed on a slow feed you would probably get a really good result. After cutting over an inch of material the insert looks like new (see second picture marked with purple pen) * The blank I wasβ¦
