Tapered drill bit recommendation

How To
1

I am looking to make a disc that can be used to hold flowers in a vase. The stems are wedged into the holes in the disc.

I am trying to use my CNC to drill tapered holes in 0.5 inch plexiglass glass. The holes at the top of the plexiglass must be 3/8 inch wide. Some of the holes will go all the way through and some will only go partially through.

I tried using 1/8 end mills and cutting contoured circles of various depth and diameters, but it took too long, and the ridges in the holes prevent the stems from sliding in and wedging.

Does anyone have a recommendation as to the tool it to use (preferably a link to a seller), and if there are any recommended approaches to setting tool paths to achieve this?

Is it possible to use V tooling which have an appropriate angle to match what you wish to cut?

What angles do you need?

How much of a taper? Could you clear with and endmill, then go around the perimeter with a V bit?

It would need to taper the full depth. So if it starts at 3/8 it should go down to 1/8. Kind of like an ice-cream cone

That’s pretty close to a 30° taper. You could use a V-bit

I was going to say the same thing as @neilferreri said. There are different types of V-bits out there for taper. Note the height of the cutting edge to the bits. Actually using a long enough 30 degree V-bit, you could use advanced v-carve to cut out the diameter of the 1/8 inch and the taper will be cut for you from the tool. But make sure to click the clean out tool in the menu when setting up your toolpath. If the tool you have isnt long enough then you will have to step program it to make each pass for the taper and blending in each step to the previous step.
