Using burrs
Using burrs
I have a bunch of 1/4"shank carbide burrs. I know they can be used in hand grinders, but can they also be used on a vertical mill to take LIGHT cuts and rough shaping; specifically on aluminum?

Heck yes. I used one to clean up the ball socket in my Acculock vise several years ago. The vise part was cast iron, and it worked very well. Notice that the ball was angled to the cut so it wasn't cutting on the crown of the ball.

They clog really easily, so spray liberally with WD-40 or similar.

-----I used this 1/4 carbide burr to remove half the syncro teeth on 3rd & 4th gears--and half the teeth up inside the synchro collars when we were wanting to slickshift our BW T10 in our salt flats car
---at first I had reservations about breaking the 1/4" burr but it lasted thru all the teeth with no issues

Undercut the 2nd gear dogs on my Hayabusa gearbox, stop it jumping out of gear using carbide burr.
Hate using them on my die grinder, when they grab it can be a handful and full face mask is mandatory, fine shards of steel are dangerous.

I was going to say, if doing anything in aluminum, use plenty of something to flush the swarf, but Russ beat me to it. Oh, i guess I still said it.

The round burrs are handy for removing the ridge formed on the Harley Evos rocker arms, cleans them up nicely.

Re: Using burrs
just be careful not to let them get too hot; the braze melts and they get decapitated.
As I found out...
When cutting steel, they produce waste in the form of tiny sharp needles.
Ouch.
I used a barrel shaped one with a ball bearing guide to make round holes in an object too large to mount on a machine.

Looks like you were using a router with the burr. Much too fast speed.liveaboard wrote: ↑Wed Mar 04, 2020 5:07 pm just be careful not to let them get too hot; the braze melts and they get decapitated.
