each job. Could be the humidity is non-existant out here so the wood is really dry...even putting masking tape didn't help too much...only slightly splintered one of 20. Time consuming being so nervously careful...if I monge one up I end up losing money.
Crash, I'm going to give you something that I learned, while working on boats.
When drilling into fiberglass, if you start out with *any* kind of drill bit, the gel coat ( the overcoating that goes over the color layer) splinters and takes pieces of fiberglass with it from around the drilled hole. Primarily because it's brittle. This leaves the uncolored fiberglass, showing all around the edges and can sometimes splinter a big chunk of the color coat away, making for a pretty ugly sight. A way to avoid this is to push the point of the drill bit into the fiberglass with some amount of pressue and run the drill backwards. If you make the indentation deeper than the angled tip of the bit ..... then slowly run the drill forward, you'll find that the tearing around the edge of the hole is reduced considerably. This works especially well when drilling into vinyl at all times of the year. Sometimes, here in the cold climate, in new construction, the vinyl on doors and windows can crack from being cold. Running the bit backwards, heats up the vinyl and then it drills a lot better.
Another way of course, is to start with a smaller drill bit and work your way up. But, time consuming. But sometimes, depending upon the material, just a few bit changes will do it. And, of course, once you break through, any sharp bit will do. Masking tape helps .......... only sometimes.
I've never tried this with a brad point bit, because I've gotten used to using standard point. But, just thinking about it, it just might work better than a standard tip bit.
I expect we can all be prepared to see this show up in Bass's FAQ.
By the way, are you really using a "bell hanger" bit or a flex bit? I can see using bell hangers in new construction, where you can see where you're drilling, but I use all flex bits, regardless. No reason to carry two kinds of bits when one will do. The flex bits are so much more maneuverable.
