If you are faced with the challenge of drilling an extra deep or long hole in masonry, you know it can be a real challenge to find a hammer drill bit long enough for your SDS hammer drill. Usually you can find a bit that will drill up to about a foot, but some projects, especially projects that are older buildings or additions will require you to drill deeper holes. Now what? Be prepared. We offer a full line of SDS bits from 3/8″ to 3/4″ diameters that will give you a drill depth of anywhere from 16″ to 34“! If you need a whole a little wider, you can drill a pilot with the smaller diameter and then come from either side if possible. We have bits 7/8″ diameter to 1-1/4″ that have 16″ diameters. If you have an application that requires a larger hole, consider one of our thin wall cores designed for use with SDS hammers. You will find a size range of 1-9/16″ to over 4”. There thin wall design reduces the amount of friction allowing even small to medium size SDS hammers to handle up to 2-1/2″ hole or more with ease.
Is my hammer an SDS hammer? Sometimes we get the question, especially with Hilti hammers, is my hammer an SDS hammer drill? If it is a smaller hammer, likely so. It can get confusing, with some brands. For instance, Hilti calls the bits for SDS hammers a TE-CX bit. An SDS shank hammer drill bit is about 3/8″ diamter and has to dimples opposite each other, and two slots opposite each other. If that is what you have, any SDS bit will fit in to your hammer drill. If the shank is about 3/4″ you likely have an SDS Max or possibly a spline bit. These are typically bigger, and noticeably heavier tools.
