Wow that 1/16" cutting bit is expensive !!

[TurtleCove]

I'm cutting out templates in acrylic.
I don't know whether to use 2 flute or 4 flute.
I imagine I'll need to perform a plunge, for my initial entry into the cast acrylic, and each time it moves to a new shape, and drops into the material again.

I'll be cutting 2D shapes, out of 3/16" thick cast acrylic. Curved lines, and such.
I'll use dbl sided tape, and tape it to a wood backer board.
I've got a Rock Chuck.

I would use a two flute 1/8" bit with a 1/2" LOC. (Just like the one I showed in the ER adapter.) I would be worried about a 3/16" deep cut with four flute and only 1/16" diameter. (Also, I would be worried about the jerky cut out routine of 1.186 breaking the 1/16" bit.)

You would also need more passes to be safe with a 1/16" bit. Three passes to safely cut the acrylic.

I would do two passes with the 1/8" bit pictured and feel safe.

Edit: I you are going to use double sided tape to hold the acrylic, you will not need tabs and so use the bit path instead of the cut path. It is much smoother in 1.186.

Anyone know if there is anyplace in Canada to buy bits that work in the Carvewright . I use the carvetight bits. When you order from Carvewright it costs $45 in shipping which is rather expensive.

Consider using the ER11 adapter. See previous post.

Where do you get an ER11 and what bits and where do you get them for the ER11

Duncan, I've been buying more and more of my bits on Amazon. Does that work for you?

[bergerud]

I do not think Amazon ships such things to Canada. The ER11 adapters are on

With the ER11 adapter, you can use bits with 1/8",3/16", or 1/4" shanks.

Have you tried ebay for your bits. I buy from drillman1 on ebay. He has both 1/16 bull nose and 1/8 straight. Plus they are 4 flute, which I feel carve better.

I just ordered a 1/16" cutting bit from Carvewright. Not cheap.

Anyone know if the cutter, in eBay auction 130876407128 would work in our machines?
I'd only be taking very small cuts .1" deep per pass, in cast acrylic.

I have about 10 of them haft price if your still looking for some or anybody else plus shipping of course
