Johnson Tools Industrial TCT Masonry Core Hole Saw Set | 30-160mm Modular Wall Opener

In professional HVAC installation, commercial plumbing, and electrical pass-through projects, tooling survival rates directly dictate onsite labor profitability. The Johnson Tools TCT Masonry Hole Saw Set features virgin Tungsten Carbide teeth high-frequency brazed to a toughened alloy body. Engineered with an advanced Dual-Stage (Alternating Outer/Inner) tooth geometry, it evenly distributes high-impact shearing forces from rotary hammers to entirely prevent wall-binding. Powered by a highly modular shank matrix (110mm to 410mm), a single arbor seamlessly drives 23 distinct cutter diameters (30mm to 160mm), drastically lowering inventory overhead for wholesale distributors and fleet operators.

Tungsten Carbide Tipped (TCT) Masonry Core
Dual-Stage Cutting Geometry (Alternating Teeth) Moving beyond standard flat-tooth configurations, our cutters feature alternating Outer Shearing Teeth and Inner Crushing Teeth. This specialized geometry splits the mechanical load, reducing per-tooth impact resistance by 35%. It guarantees smooth, non-snagging penetration through abrasive red brick, breeze blocks, and aerated lightweight concrete (ALC).

High-BPM Survival Matrix (Quenched TCT) Built explicitly to survive the brutal BPM (Blows Per Minute) of commercial rotary hammers. The Tungsten Carbide tips are securely brazed using a high-tensile silver-copper alloy, while the 130° split-point pilot bit prevents bit wandering during initial surface engagement.
