The Tork Craft TC911017 Heavy-Duty Carbon Steel Hole Saw is a professional 70mm cutting tool designed for demanding construction and industrial applications. Manufactured from high-grade carbon steel with hardened teeth, this hole saw delivers exceptional performance when drilling through wood, plastic, and metals up to 4mm thickness. The advanced tooth geometry ensures fast, clean cuts with reduced binding, while the black oxide coating provides superior heat resistance and corrosion protection. Compatible with 3/8″ hex drive drills, it includes a tungsten carbide tipped pilot bit for precise centering in tough materials. With an extra-deep 40mm cutting capacity, this industrial-grade hole saw is ideal for plumbing, electrical installations, and HVAC work, particularly for large diameter pipe penetrations. The reinforced steel body withstands high-torque applications, making it a reliable choice for professional tradespeople and contractors.
