Carbide Burrs

[BadBamaUmp]

Anyone use a carbide burr in stead of a small wheel attachment for finger grooves and such? Where did you get them, Grainger only has 1/2" I'd like a 5/8 or 3/4 burr.

I forget who, but one of the top makers uses the sand paper sleeves around the rubber drum. He mounts it in a router for maximum power.

RA,
I do that now, but burn up a lot of paper sleeves like that. Was thinking that the carbide burr would do the metal removal and I can shape the wood with the paper. Local machinery sales has what I want for $35. That's about 7 packs of sleeves. It would save me some $$$

1/2 is the largest I.ve seen in the carbide. I only use the carbide for soft metals like aluminum though. I'm pretty sure you can get the high speed steel burrs in larger sizes, as a matter of fact I think Lowes sells them to 3/4".

Peter, would HSS work better than carbide to work annealed 1084?

I might have a lead for you on carbide burrs.The name of the company is B&J manufacturing company. I got the lead from a jet engine repair facility. I can't even tell you if they have a website. The next lead is guaranteed lol Snap-On has or can get nearly any size carbide burr I have a 1/4,3/8 and 1 inch in 1/4 inch shank I use them in a die grinder(pneumatic)the 1 inch is a bear to use It places a tremendous side thrust on the drive gearing of a hand held tool.

Cool, the local machinery place sells a 3/4" carbide burr for $35, I can get a 3/4" HSS burr from MCS for about $25, wondering which would be most effective.

I suspect the carbide may last a little longer but remember to slow either the carbide or HSS down. Use them in a router and their life will be pretty short. The carbide I use have very wide spaces to allow good chip removal on soft metals. I haven't used a standard burr in carbide. For the difference in price, I think I'd try the carbide just to see how well it works!
Let us know!
