1/2 Shank End Mill

[duhtrev]

I have a 3-axis cnc router table using a Dewalt DW618 router. Up until now it's been easy to find end mills for the 1/4, 3/8, and 1/2 collets. However, I'm now looking at doing a larger project which calls for 5/8" and 1" ball end mills. Can anyone help point me to where I might be able to find 1/2 shank end mills with larger cutting heads.

The material I'm using calls for the following:

1" Ball 4FL Roughing HSS-Co
5/8" Ball 2FL Carbide
1" Ball 2FL HSS-Co
5/8" Ball 4FL Carbide

Thanks in advance.

What are you cutting? Will wood router bits work? You can get them in large sizes with 1/2" shanks. They usually call them core box bits.

I'm cutting 4" blocks of RenShape 5045 foam and 1" thick Renshape 5179.

I'm not familiar with core box bits, I'll have to do some research, thank you.

duhtrev,

I know this is kinda late but did you get your tooling problem fixed? If not, I can point you to a place that can make exactly what you are looking for. They make special tooling like this for me to cut cylinder heads in both cast iron and aluminum.

Larry,

I did manage to work through my problem and found bits close to what I needed from the links provide by other members, and they got the job done. However, I would be interested to know your resource for future projects.

Thanks,
Trevor

What I will do is look through my invoices and pm you their information and send you a print of the last piece they made for me for your reference. They will make almost anything you want but this will give you a good idea. The main thing for what you are wanting to do is the number of flutes and the reliefs. They made me a cutter for aluminum and a totally different one for cast iron. The cast iron cutter is absolutely amazing if you could see it.
