Product Description

By entering your model number, you can make sure that this fits.

Solid carbide tools have a longer tool life and can cut at higher speeds than other substrates, but they are more brittle and require rigid toolholding systems.

For turning and milling carbon and alloy steels, tools steel, and stainless steel, a multi-layer coating TiN/TiC/TiCN/TiN is used.

When compared to uncoated grades, this grade has a longer tool life.

Slotting and slab or straddle milling are two applications for this tool.

Questions & Answers

Is it possible to mill steel with these?

7075 aluminum, Grade 40 cast iron, and 17-gauge steel have all been machined by me. With these, I've used stainless steel four times and am very happy with the results. Despite the fact that the stainless steel I work with is a difficult material to machine, these inserts produced a nice surface finish on all of the materials I've used them on. They're mounted on a Shars R8 surface mill, which is 3 inches in diameter. Most mild steels machine similarly to the hard 7075 aluminum I frequently use, so I'm confident you'll like these. When I machine the 7075 aluminum with a 2500 rpm cutter speed and a light cut, the part has a mirror finish, which I find impressive. Many of the other inserts I've used have left galled rough finishes in a similar state. The better the performance of these, the more rigid your milling machine is.

The inserts are not all the same size, resulting in

3/5

Because the inserts aren't all the same size, the cut is uneven. They're similar, but if you look closely at the corners, you'll notice that the shapes are slightly different.
