Columbia Tools’ new patent pending Pump Action Sleeve on both the Columbia Automatic Taper and the Columbia Predator makes cutting a easier than ever. Using Teflon bearings that create extremely low friction, the smooth feel gets better the more you use it.
This new cutting sleeve is not only the smoothest sleeve on the market, but is also the first adjustable sleeve on the market. And with the elimination of wear parts, this sleeve is extremely long lasting.
