I need to drill holes about half-way into the wood, and each time I do the wood splinters pretty badly. I can’t really use the tape/piece of wood method because the hole doesn’t go all the way through the wood. How can I prevent the wood from splintering? The bit is 1/8” and the surface is slightly curved.

Your bit is dull. Take smaller bites. Worst case is to predrill with a smaller bit.

When I drill holes in places where I don’t want splintering, I run the drill in reverse and gently push the bit onto the surface of the wood. This allows the bit to score the wood and make a very clean entry without splintering. After the scoring is done, put it in forward and drill away.

Tried brad point bits? I just got these for Christmas so I can’t personally recommend them but they were recommended highly:

You could also try sharpening your bit.

If it’s pine it’s going to splinter. What kind of wood?

What Tim said. I’ve had them for years, they make a nice clean hole, both entry and exit.

Brad point bit that’s what they’re made for.
You can get a set reasonably cheap.
