#Silver and Deming (S&D) drills can also by specially ground for use as chamber bits. They tend to cut cleaner and faster than the modified spade tip bits. While possible to grind yourself, it is more difficult. Custom ground bits can be ordered, but they are considerably more costly than the modified spade bits.

#Customized tobacco chamber bits that resemble spoon bits are used by many of the Danish pipe makers, and are now being used by many others. These are nearly essential for the shape first method that involves holding the previously shaped stummel in ones hands, and pushing it into the spinning bit. They can be difficult to get. PiaPipes ([[Tom Eltang]]) has them on their [http://piapipes.com/product.asp?product=600&sub=48&page=1 Website]. In the past, [[Brad Pohlmann]] a highly skilled machinist and pipe maker also made a batch of excellent chamber bits in this style. | #Customized tobacco chamber bits that resemble spoon bits are used by many of the Danish pipe makers, and are now being used by many others.

Bur | Bur Bits are another type of bit which can be used to drill the chamber. Standard bur's having a 1/4 in. dia. shank will fit most any drill chuck and will drill holes with straight or tapered sides and rounded bottoms, perfect for pipe bowls. They are available up to 1 in. dia. round-ball shaped, and 3/4 in. dia. oval-egg, and tree w/radius end shapes and in other shapes and sizes at www.mcmaster.com (mfg. www.fullertontool.com) and some other tool suppliers. They drill very cleanly, except some spiral marking on the sides which can be sanded out, but they are very slow, and will burn the wood if you drill too fast. | ||
