About this product
The DEWALT SDS Plus Extreme 2 drill bit is designed for fast drilling of plug, anchor or clearance holes in masonry, stone, concrete and brick/block work. It has a diameter of 16mm and an overall length of 160mm, supplied as a single bit.
The bit is made from a superior carbide grade for long life and durability, with a hardened steel body for extra strength and reduced breakage. An optimised mounting shank gives good grip and power transmission, while the flute design helps clear debris efficiently. The solid two cutter head with individual cutting tips is intended to give faster, more efficient drilling with better penetration.
