I am making some lacing things like this https://goo.gl/photos/gb6i2ZJzBazkmSSj7
They require drilling / milling a lot of holes. I was making the holes 1/8″ the same size as the end mill which is ok but I think it would be better if they were a little bigger. So what is the better thing to do get a 3/16″ bit or instead of drilling them mill them out with the 1/8″ end mill?
The other complication is I am using a dremel for the spindle which only will take up to 1/8″ so can I even get a 1/8″ shank 3/16″ end mill?September 5, 2016 at 3:52 pm #17238
I used the helical drill command under drill in estlcam. It worked pretty good but not as nice of results as I got from just straight drilling. I saw chipping and out of roundness on the top side of the piece.September 6, 2016 at 3:33 am #17264
Pretty sure for that, you’d need a downcut bit. Though never use a downcut bit to make a hole that’s the same size as the bit. Needs a place for the chips to go.September 6, 2016 at 3:41 am #17265
I was using a straight fluted bit. I didn’t see a issue with chips but I am not drilling it in one shot it is coming out several times on each hole.September 6, 2016 at 12:57 pm #17285
Weird. I’m using an upcut mill in this video to cut the countersinks for my spoil board. Doesn’t look too bad.
