Point roundover bit

[Kyle Stapleton]

I'm looking for a point roundover bit with a 1/2" shaft and 1/2" R.
Can only find one with 1/4" shaft.

I would also like any info on cutting with one in plastic (3/4" playboard)

Thanks,

[Kyle Stapleton]

HDPE is the plastic.

Thanks, got any tips on cutting with it?

Just the usual, start slow and increase until cut quality decreases, then back off 10%.

Also, check out the cut/roundover if you don't need a sharp point

That is what I thought you would say.

“Also, check out the cut/roundover if you don't need a sharp point”

Recently I had a customer who wanted a radius on both sides of a bunch of small parts… I used the #1275 plunge radius bit. This bit has a 5/16” radius with a ¼” flat. This allowed me to first run the radius on both sides of the ¾” material and then cut out the remaining 1/8” with a ¼” bit… I used tabs on this cut, this left the tab in the center of the part that I delivered to him still in the matrix.
This method made a job I wanted to turn down, very simple to do! The customer had a little bit of clean up, but it was lots simpler and safer than hand routing 2” X 3” parts!
