TCT Hole Saw - (25mm)

A 25mm hole saw with tungsten carbide teeth. TCT is the distinction that matters: an ordinary bi-metal hole saw is made for wood and mild sheet, and it blunts almost immediately in stainless, hardened steel or thick plate, while carbide teeth keep cutting through material that would destroy it. At 25mm it cuts the holes that services need - conduit and gland entries into steel enclosures and trunking, holes through steel section and plate, tank and casing penetrations, and openings in stainless worktops and sinks. Run it slowly with firm steady pressure and cutting fluid; speed is what kills carbide teeth. Clamp the work and never let the saw grab as it breaks through, which at this diameter it will try to do.
