| Thin Wall Percussion Core Bits Used to bore large diameter holes in brick, block, and masonry. They are a lighter weight, faster, cleaner cutting alternative to standard thick wall percussion cores. The "inside" core depth is 3". The T-COR Series is also compatible with smaller SDS drills, where thick wall percussion cores are specifically designed for bigger drill motors only. Each of these thin wall cores require a screw on the shank and a drop-in starter bit which are not Included. Not recommended for hard slag-concrete. |
