The drill bit does an excellent job of pulling the shavings out of the core. The amount of wood needed to be chiseled off is very little. The blade of the chisels are super sharp so with good care you will be able to make many square holes with these. If you don’t have a select speed drill press, I recommend drilling a bit and backing off for a second then slowly go through like that to reduce heat.
What I like best is if you use little pressure when getting to the other end of the block you get a perfect edge that doesn’t really need trimming or sanding. These bits are well made with good steel and will last a long time. If you need a lot of this type of drilling then I suggest you get a set as it is worth it in the end.
It's smooth sailing with this product. Works ok for me. Great work guys.
