Bits

I have a Shark HD with an extended bed and I'm running a water cooled spindled. The spindle is great since I don't have the noise of a router, but I am limited to 1/4" shank bits. I was wondering if anyone is aware of any company making a 1/2" end mill and a 1/2 ball nose on a 1/4" shank.

Thanks!

ER-20 collet?

What collet does the spindle use, ER20, ER25 etc? You should be able to get collets in any size you want to suit any shank. I have them in 1mm right up to 16mm for my spindle.

Thanks for elucidating Adrian

Doing 4 things at once:)
ER-20 offers 1/8-5/8" collets.

He maybe on ER11 which goes to 1/4
You can find larger tooling dia on 1/4 shank from Amana, mostly in their straight plunge CT tools

Yep, just looked it up. The Shark HD4 comes with a little ER11 collet.

Just use carbide tipped straight bits and corebox bits. You can get a variety of sizes with 1/4" shanks.
