I’m using Titanium Nitride Twist Drill Bit to drill all the way through wood, every time I do that it cause splinter on the other side, is their a way to prevent this?

One way to prevent this, Steven, is to clamp a backer board behind the wood. This should prevent splintering.

Another idea is to drill a very small hole all the way through first, then drill your hole half way through with a bradpoint bit. Flip the piece over and drill again from the other side.

Scott and Wayne are both right. I use the back up board more often because it’s usually easier. I don’t always clamp it, but it must be firm against the workpiece.

I got a huge improvement on the drilled holes just by working with Brad point drill bits, I got to say that the back up board its a great idea, but also the Brad point drills wil prevents skating.
