Drilling hard wood

Hi , I new to wood working. I need to drill many 3/8 inch holes through 5/16 ( thin ) hard wood.
Can someone tell me what kind of drill to use. and are there any tricks to keep the wood from splitting. thank you for your help.

I'd use my drill press with a forstner bit. I haven't mastered avoiding tearout entirely, even with a sacrificial tabletop, but I'd guess that I feed to fast. Masking tape can help for cuts, I've not tried it for drilling.

clamp the board between two pieces of wood, then drill your holes this way you will not have any tear out on either side. I would start with a smaller bit and work up to a larger bit.

Drill press and Forstner bit with a piece of scrap wood for a backer to prevent tearout on the bottom. Move the backer after each hole.

For a 3/8in hole, you can use brad point or Forstner. The brad point may cut a little faster. A lot depends on the quality of the bits.

I have a good quality Colt brad point set which cuts fast, but my 3/8in Forstner is part of a cheap Chinese set. It does not cut fast.

As others have said a backer board is important. You may need to clamp, and you should move the backer board each time so you cut into solid wood in the backer board.

A good Forstner or bradpoint should give you a clean entry hole, and as suggested a fresh back up piece for successive holes.

A sharp bit is important no matter which type you use. The best way to do it is just how everyone's suggested..with a backer. You could also use a brad point or spade bit and drill through just enough that your center point comes through the bottom. Then, just flip it and drill the other side.

Either way, I'd use a drill press to make sure your holes are nice and straight
