Router bit

I am thinking ahead as much as I can. Just put an order in for some cutters for the Farm boy as well as one for the rob roy later on. (they did not have the size I wanted)

With the farm boy I need to round over some of the edges on the Ali parts of the build, would it be possible to use a wood router bit for this operation I have some HSS ones as well as TCT tipped ones.

If this is possible it will save having to order from a different company yet again.

It just seems as when ordering bits and pieces I have to order from many different companies instead of ordering from just one.

I know Arceuro have a metric cutter which would do the job so if push comes to shove I will order that one but that will be yet another postage cost just for a small item. I do try to reduce postage and bulk things together.

I have successfully used a tct router cutter for corner rounding on Aluminium and Cast Iron. High spindle speed and don't get greedy with the depth of cut.

Only difference between a router bit and a proper corner rounding cutter is the shank diameter, as Chris says use a high spindle speed and take it gently. Both carbide and HSS ones work equally well.

Give it try. What's to lose? (apart from a router bit of course). I'm guessing the carbide insets in woodworking bits might be a bit thinner, and maybe not as well supported. I'd try it with 1//2" shank bits if you can, for increased rigidity if nothing else.

As Chris suggests, take it easy. Good luck and let us know how you get on.

Thank you Guys. At the moment this is the only job I need it for

I've done it several times. The only thing you have to watch is that if you are working into an internal corner then the generally larger diameter of a router bit won't get into the corner as far.

Diameter of cutter also determines speed so a router bit would generally need to run slower than the smaller dia of your typical milling cutter but a sit is aluminium you should be able to give it some beans.

Part of what needs cutting I will need to stop short anyway and finish those by hand and blend them in
