Hey Auntjemimma, hey Doconefall, hey Pat, hey Michael, hey Mrd, hey all,

@Doconefall

Get the el cheapo shelf pin jig like the one from kreg.

If you design and build a new piece of furniture, and many specimens of them, you would do the holes with the CNC, here I think I would use a

@Aiph5u

downcut bit or a bit like this one which has very steep upcut spiral angle of 15°, which is a compromise between the ability to evacuate chips and trying to minimize tearout at the surface:

Sorotec 2-Flute WOOD

A CNC router/spindle runs usually much faster than a hand power drill so I think what Michael said applies:

@SailorMike

If […] your holes are 5mm […], you can use a 1/8" end mill and an inside profile cut with a spiral ramp.

But I agree with @Doconefall in that in some situations, using a jig (like the Kreg Shelf Pin Jig) can be handy. You would use that when you retrofit such holes on an existing piece of furniture.

As someone who worked exclusively with hand tools for a very long time, I always marked such holes with my 12-inch incra rule (an extremely useful tool!),

and drill them with my japanese Star-M No. 4 power drill auger bit

with using the extremely useful and

@Aiph5u

ingenious Star-M Depth stops :

The plastic cap rotates freely and stops rotating when you reach desired depth. I use a set of them, from 3 mm (=approx. 1/8″) drill diameter upwards. Picture shows ⌀ 15 mm drill (=approx 19/32″).

Available here or here

by using my Schröder (Wuppertal) 2-speed hand drill

(my specimen is 70 years old, looks much older than on this image )

Maybe you know slow food, then you imagine what is slow woodworking – very healthy !

Nearly as healthy as doing a zen meditation while your robot (=the cnc machine) does the work
