The Hole Saw with multiple Carbide Teeth (TCT) which cut into the widest range of materials. With a unique auto-precision grinded carbide tooth style for clean and high performance cutting. Up to 50 times the lifetime, 2 times faster and 3 times more holes per battery charge. The beam welded Carbide tipped teeth are made of a specially developed fine grain, highest grade carbide, resulting in outstanding cutting performance and product durability. With a cutting depth of 60mm (2 3/8) you can make deeper holes in a single pass. Fast cutting in all common materials like e.g. (stainless-) steel, wood (with nails) , plastic, soft tiles, gypsum, soft bricks. Easy core ejection because of the optimized release slots. -Widest range of materials -Up to 2 times faster & 50 times the lifetime (compared to Bi-Metal) -Optimized heat resistant carbide teeth, lesser cooling needed -Cutting depth 60mm (2-3/8) for deeper holes in one pass -Large clearance of chips: specially designed slot
