1/4" or 5mm end mill depending on your shelf clips, not too hard, just take a piece of scrap and adjust your settings. ---

1/4" Jenny bit? Thats the one I have laying around. Since Im cutting all the way through the material I wanted to make sure I could get a clean cut on both sides. ---

Downcut bit. Cuts clean on both sides. Just make sure the first plunge is at least .250 or greater ---

If you’re using Vectric, and your holes are 5mm or 1/4", you can use a 1/8" end mill and an inside profile cut with a spiral ramp. It takes a little longer, but you probably have the bit on hand. I’ve used this with multiple sizes of holes, and it works as long as the bit is smaller than the hole diameter and doesn’t leave a substantial amount of material inside the hole. ---

But I agree with @Doconefall in that in some situations, using a jig (like the [Kreg Shelf Pin Jig](https://www.kregtool.com/shop/cabinet-solutions/cabinet-drawer-shelf-jigs/shelf-pin-jig-14/KMA3225.html)) can be handy. You would use that when you retrofit such holes on an existing piece of furniture.

> [@Mrd](#): > > Downcut bit. Cuts clean on both sides. Just make sure the first plunge is at least .250 or greater Don’t straight plunge with a downcut. The chips are pushed down into the hole with no where to go, and the hole tends to get blown out and enlarged to more than the desired diameter. Most drill bits aren’t rated for even the slowest speed on the Makita, but some are: [Drills – IDC Woodcraft](https://idcwoodcraft.com/collections/drills) One option is to use a downcut bit of a smaller diameter than the hole, and use a boring toolpath the helix into the holes. ---

Thats why i thought the Jenny bit might work well, it has a small section at the tip thats an upcut. ---

I use Fusion 360 free personal use version. There is a menu for drilling. I use full retract strategy with a regular drilling bit and slowest speed on the Makita router.
