You just can't have too many options when it comes to drills and bits, or I guess any other tooling! Pipe making requires a combination of specialty or customized bits, and off-the-shelf drills. Even the off-the-shelf drills used are sometimes hard to find locally and must be ordered. | You just can't have too many options when it comes to drills and bits, or I guess any other tooling!

#Spade type bits that have been specially ground are the easiest to acquire. They are inexpensive, and easy to make yourself by modifying off the shelf spade bits.

#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 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 shaped at www.mcmaster.com and some other tool suppliers. As always, you have to drill slow, and be careful not to burn the wood. | |||
