Looking into getting a depth stop chuck. I have a nice c15/ti15 combo set, have some drywall hanging coming up for a home reno job. Seems like this might be a good idea to get - if the price is decent. New is a bit much for me right now. Looking to buy or maybe trade, I have a pair of parallel guides that I've never used that I would be looking to trade as part of the transaction, if interested. Thanks!
