You need to get a counter sinking bit. Has shoulder on it, that way the shoulder of the scew will not split the wood. You get them for the specific size screw you are using. Any hardware store should have them.

you could always just use a bigger bit to make your countersink after you have drilled your pilot hole...

You could be using screws that are too large. Are you using 3/4 MDF? I'm sure you are. I use #6- 1&5/8" drywall screws. Make sure they are centered and you shouldn't have it splitting.

They're all right. But if you can swing it, a finish nailer is a great tool to have.

One thing you can do,aside from using the proper size screw is to shoot some good quality wood glue into the holes before you put in the screw, that way any small splits will get filled and bonded then just wipe off the excess glue with a damp sponge. Works great!

In a world full of copycats, it's great to be an original!

P.S A brad nailer will also do the job but $$$ pricey

If you get a countersink, get one with a tapered bit.

I personally, am a fan of just a plain old screw driver; I screw in all of my screws in by hand, that way I know if I am putting too much torque into it so I don't split the wood. Also that wood glue trick works wonderfully.

I have a special bit that will drill the pilot hole as well as drill a wider countersink at the top to make the screws flush.

I am kind of a perfectionist when it comes to my boxes, even if it means hand screwing an entire box of drywall screws into one box, as long as it looks nice and people notice my craftmanship it doesn't matter how much blood sweat and beers went into one box.

eh? what did you just say?
