Hilti has come up with a solution to the problem of cleaning dust out of holes prior to setting anchors — a hollow drill bit that allows you to collect dust from holes as they are being drilled. A 1 1/2-inch vac port encircles the shaft near the back of the bit so that air can be pulled through holes at the tip. This speeds drilling and eliminates the need to use bottle brushes and compressed air to clean the hole. Available in both SDS Plus (model TE-CD) and SDS Max (model TE-YD) in sizes ranging from 1/2 inch to 1 1/8 inches. Price: Starting at $80. COO: Hungary. 617-268-8235. us.hilti.com.
