Arbors and Accessories Assembled core ejector attached to a hole saw. After the hole has been drilled, the core can clearly be seen at the end of the pilot drill. Core Ejector A SIMPLE, BUT HIGHLY EFFECTIVE METHOD OF EJECTING THE CORE FROM A HOLE SAW AFTER COMPLETION OF THE CUT • Select the appropriate size of ejector for the hole saw • Where it is necessary to assemble the two parts of the core ejector, twist the spring on to the ejector plate until it locks in place • Twist the spring on the assembled core ejector over the pilot drill until the pilot drill is protruding from the plate • Drill the hole NOTE Using the core ejector will reduce the cutting depth of the saw. The table below lists the recommended optimum maximum material thickness for each type of hole saw. The core ejector will function at greater material thickness than those listed, however its effectiveness will diminish. Cat.
