Drilling into the Gelcoat

Ahh ok yea i know those bits just didn't know the correct name of them.

Only time i do a step up bit is when im worried about placement and or drilling from the inside out.

Also wondering if you need to continue to drill up in size from small to get to the hole size you want if you are using one of these? I wouldn't think so? Past members have posted that you start with a small bit and work up? I would imagine that is if you are using a standard bit right??

Viking - learn from my mistake. When using a forstner bit, drill a very small pilot hole to double check placement and it's a guide for the forstner bit. Next, with forstner bit and drill in reverse, go full bore with the drill, no holding back. If you slowly drill to make sure things are going ok or you are not using enough pressure (not extreme sweat producing pressure, but good firm pressure), the bit may start to skate around and make an nasty oblong hole. Use firm pressure with drill going full bore, you will get a beatiful hole. Trust me, I know!!!

Hope that helps.

Thanks OutbackV!
I'll do that! Going to buy the bit today. What are you guys doing then when getting to the carpet? Just cutting it out with razor blade?

If you referring to drilling the carpet. Drill right threw it. Most of it is glued and wont fray and tear like normal carpet. You can use a razor and get it cut out of the way first if you like.
