I am brand new to this forum, retired and have a woodworking and metal working shop for my own use. I am at best an amateur hack. My question that I posed to different people seems to get different answers so I'm just trying to sort it out. Specifically I want to drill 1 to 1.5 inch holes in steel plates using drill bits with reduced 1/2 inch shanks. I have a Jet 2HP 20 inch variable speed drill press. My question is about the chuck. If I use a Jacob's 20N Super Ball Bearing Chuck, the maximum drill capacity is 1 in. But can I use a 1.5 inch drill bit diameter with 1/2 inch shank in such Chuck? Or will I get slippage because of the excess torque exceeding the capacity of the chuck? Also I asked a supposed expert at MSCDirect this question and he said run it at a slower speed so the torque would be less which makes no sense to me as I thought torque increases at lower speed. Your feedback would be greatly appreciated.
