Gene; Smart move.
My ER collet chucks reside on my mills, and almost never get removed. (boring head, cutoff saw, but do not have a drill chuck that fits the spindles) I do have some smaller drill chucks (expensive, good) that I have on parallel shanks, trimmed so that they will go into an ER collet, and bottom out, but not stick out too much, maybe 2-3mm. The shanks I have are 1/2", so fit well within an 13-12mm collet. Sometimes it is nice to have a (good) drill chuck for the smaller drills, otherwise sometimes 3 hands are required (hold drill, keep spindle from rotating, tighten ER collet nut) John. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
