APPLICATION & ADVANTAGES :
Taper Shank drills are costlier compared to straight shank drills. Using split sleeves for drills straight shank drills can be used with almost the same accuracy as the taper shank drills.
Drill Chucks loose their accuracy over a period of time. Split Sleeves retain their accuracy for life. Furthermore there is no positive drive in drill chucks. The drive slot of split sleeves offer a positive drive which prevents the slippage of taps (& drills) as in case of drill chucks. The Split Sleeves can be used in conjunction with the Quick Change Chucks for non-reversible tapping as well as drilling using straight shank drills.
