My FIL gave me some MT4 shank drill bits: 1 5/32, 1 15/32, 1 17/32, 1 21/32 and 1 29/32". After using a couple to open up some holes prior to boring I added 5/8, 3/4 and 1" to the collection
Gonna have to add on to the shop. Warn your wife, mention the curse of the MT4 that you FIL passed on to you.
This is a great way to add a small extension on to the shop. Start small, maybe 20x30.
Knowing that all this happened on account of your FIL will make your wife fully supportive.
This like many things is new to me. Could you explain it to me with some more detail and/or better yet pics?
The scenario is to bore this 6065 to 1.5", after center drilling, I should have just gone straight to the 1 15/32"? Then do you peck a lot to break chips or how do you deal with that massive curly chip?
What I generally do when I have to drill a large hole on the lathe or even on the mill, I'll drill a small hole, say 3/16" first to the depth needed or as deep as there is flutes. Then drill with the larger diameter bit next. Very seldom step drill other than this. Step drill only if HP is an issue, like on my 9" SBL, then I'll step drill.
