What are you using for a spoil board cutter on your cnc router?

[rodjava]

I bought some great bits at http://www.centuriontools.com for my cnc router. They also sell a 3" spoil board cutter that is used to level the replaceable spoil board. Unfortunetly, this spoil board cutter is not affordable for me at the moment.

My table is 28x40 and would take some time to level it with the largest 1/2" bits I have.

I was wondering what other zoners are using to quickly level their spoil boards.

Thanks in advance.

I use the Fly cutter that is made for this purpose. I have 2 different ones A 3 in. and a 4 in. for doing the entire table my table is 5 ft X 13 ft . It would take for ever using a smaller dia tool

Boots,
I take it that it's a 1/2 shank cutter in your router for those fly cutters. What speed are you running when leveling?

Yes it is a half in shank...I run it at 12,000 RPM and 480 IPM feed rate. I draw a box slightly larger than my surface to mill and use the pocketing feature in the software and pocket mill the surface .010 deep. If you need to go deeper make another pass.

Boots,
That's great intel. Thank you.

Thanks for chiming in. I wonder what other guys are also doing.

I found a 3/4" cut width, double straight flute router bit at a hardware store, and this bit actually has cutting edge on the bottom face as well. Makes fast work of my MDF spoilboard!

Carbon Kevin,
I take it that it's a 1/2" reduced shank bit with a 3/4 cutter. I will have to be on the lookout for one of these.

1/4" shank, 3/4" cutter. It's a wood router bit, basically. I can find the brand name if you're interested.

CarbonKevin,
thanks for the offer to check. I'm leaning towards larger cutters like 1/2" shank with 2" cutter.

I see them sold here: http://www.routerbits.com/cgi-router...01065_10500+12 This is $200 cheaper than from centurion tools.

I would only use them for shallow, leveling passing cuts.

I just bought this 1/2" shank drawer lock joint router bit on Ebay for $20 including shipping.

It's a drawer locking bit which I think can be used as a surfacing/planning bit to level a spoil board.

I have priced the same bit on different websites at $40-$65 for the same C2 carbide.

I will report my findings after I get it and tried it out.

Here are pics of the two different cutters that cost $225 and $20.

I would like to hear you thoughts about my choice.

Gerry,
Those are some great options and at all price ranges.

I'm a bit frugal and look for alternative means to save money by using muliti-purpose tooling like this drawer lock bit instead of a dedicated spoil board cutter.

Thanks for chiming in.
