I've just started making pepper mills and getting along pretty good. One of the steps is horizontal boring (on lathe) the hole in the wood stock - 1 1/16" diameter. Some U-tube videos use a forstner bit, others a twist bit. I bought a very good twist bit at my local machine supply store ($81) and have been getting along pretty good except it heats up in the harder woods, like on oak. What do you experienced turners use and recommend? Thanks.
