The new Safe Set adhesive anchoring system includes the TE-CD and TE-YD hollow drill bits which make hole cleaning for anchors unnecessary. All dust generated is removed by a vacuum while drilling is in progress for a virtually dustless working environment and no need to clean the hole prior to installing the Hit-Z anchor rods. Bits come sized for 1/2- to 1-in. diameter anchors and embedment depths up to 15.5 in. Hilti.
