Can I get some help with a routing problem?


I am trying to route 3/4" MDF board with a 1/16" steel bit. I cant find carbide tips. I have already broken 5 and I have only made it through 1 and 1/2 curves. MDF is what is called for in the plans to a six lane slot car track I'm building for my grandsons. What is the answer?

What collet size and what profile bit are you using? Any bearings?

How deep are you cutting and how many passes are you making. A small bit like this is going to heat up fast and is not very strong. You will need several shallow passes to get to any real depth.

There are no bearings on my 1/16 straight bit. I couldn't find any that small. It's what I wanted. Depth of cut is very shallow.Guide slots are.0625 deep and slot pins are .225 deep.Collet is 1/4" with a straight shank bit of 1/16". Bits are breaking as little as 2 feet into route.I was doing this at this shallow depth on one pass.

If you are using a guide you may want to try a roto zip cutter. Those suckers are tough. One thing I'm not sure of if the shank is 1/4". If it is 1/8", check to see if the manufacturer offers an 1/8" collet. If not use a rotozip with a guide. ROLe.

MDF is very hard on cutters and I would recommend a carbide cutter.

What size collet can you use besides 1/4"?

Which direction are you running the router?

I use my router mainly on MDF. There is no way high-speed steel will hold up. You've got to use carbide. Instead of a straight bit try an upspiral or even a compression bit. You must use shallow passes or you will create too much heat which equals death to the sharpest bits. MDF is just compressed wood fibers and resin. You should clean the bits after use by soaking them in acetone.

As for the curve direction matter, it's hard to determine which direction if you are cutting through wood. If you are edging you would go counter clockwise (right to left) outside, clockwise (left to right) inside. I've heard it depends on the router and bit direction, but I've only known routers and bits to go in one direction, unless you are using a specialized CNC.

You can find quality carbide bits online and even Sears has them. Good brands I've used are CMT, Woodcraft, and Freud. If you are going to use a Dremel or Rotozip get those gnarly tile cutting bits - the others are useless.
