I just purchased the Supra. Thanks for the link and info!I should mention that not all Rohm chucks are the same. The best is their Sprio-I, which is near to an Albrecht in accuracy and function. The Supra-I is next in line, with 0.12mm/.0.005" concentricity, has hardened and ground wear components. All the other chucks suitable for drill press use are not as well constructed (not hardened), although they are cheaper. My suggestion is that if you go for a Rohm keyless chuck for your drill press, lathe or mill then at least get the Supra-I. They are quite good - I own several of them - although a Classic Series Albrecht is a cut above.
The one I linked to in the post above is a Supra-I.
I have been using WD, but in trying to eliminate all possible problems I just purchased some proper cutting oil. Thanks!What are you using for cutting fluid?
I have an oilcan next to my drill-press with Marvel Mystery Oil. Others may use different stuff but I find if start the hole, then give it a little squirt, then drill I have much better success, also give it another squirt if the hole is deeper than 1/4".
If you're drilling dry that may be a large part of the problem.
