Johnson Tools Heavy Duty Concrete Wall Hole Saw Cutter Set (30-160mm), SDS Plus & Round Shank Core Drill Bit for Brick & Cement
Master Tough Masonry with the Johnson Tools Concrete Core Drill Bit Set
Whether you are an HVAC technician installing a split air conditioner or a professional plumber running 4-inch waste lines through a solid brick wall, standard drill bits simply won't cut it. The Johnson Tools Masonry Hole Saw Kit is built to turn hours of grueling wall-chiseling into minutes of smooth, controlled cutting.
Engineered for the Jobsite
-
High-Grade Alloy Construction: Forged from thick, hardened steel bodies that resist warping under extreme torsional load.
-
Optimized Tooth Geometry: The asymmetric carbide teeth distribution breaks up concrete aggregates faster while requiring less downward physical pressure from the operator.
-
Dual-Shank System: We include both SDS-Plus (for your heavy rotary hammers) and a Standard Round Shank (for traditional 1/2" chuck power drills).
