Drilling with Shapeoko

[AnonymousPerson]

I would imagine that the biggest problem you would face with this type of drill chuck is the accuracy, specifically the runout once a drill bit is held in it.

Do you reckon doing initial pilot holes with (say) a 1/8" drill bit first would help there? 1/8" is a standard available collet size, so no weird adapter needed for the pilot holes.

I've been drilling MDF and aluminium (6082 T6) with a 1/8" (3.2mm) drill bit every now and again. Only about 100 holes in total so far. That's using ~5500 rpm (lowest setting on my spindle). The drill bits themselves don't seem to have any wear at all yet, so it's not damaging them that I can see.

I run a 1/8 at a around 5000rpm, you have to really slow down the plunge rate of peck drilling. I think I was going around 50mm a min earlier in the week
I’m running everything from Carbide motion but am playing with ugcs
