The CMT 550-127X Multi-Purpose TCT Hole Saw delivers a 5" (127mm) cutting diameter designed for professionals who need one versatile hole-cutting tool across a wide range of construction materials. Built with a tungsten carbide-tipped (TCT) cutting edge and a right-hand rotation design, this heavy-duty hole saw tackles wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles with equal confidence. The hexagonal shank interface and 6-tooth carbide configuration make it a reliable choice for contractors, electricians, plumbers, and remodelers who cut large-diameter holes every day.

Key Features

• 5" (127mm) Cutting Diameter with 60mm Cutting Depth - sized to handle standard large-diameter penetrations through walls, floors, and ceilings in a single pass, reducing the need for multiple tool setups.
• Tungsten Carbide-Tipped (TCT) Construction - HW Grade Material - hardwearing carbide teeth maintain a sharp cutting edge far longer than standard bi-metal designs, meaning fewer blade changes and lower cost per hole over time.
• 6-Tooth Configuration - balanced tooth count delivers smooth, aggressive cutting action across both soft and hard construction materials, reducing chatter and improving hole quality.
• Hexagonal Shank Interface - locks securely into compatible arbors and prevents the blade from slipping during high-torque cuts, giving the operator better control and a more consistent hole.
• Right-Hand Rotation (RH) - matches the standard forward-drive direction of cordless drills, corded drills, and drill presses, ensuring immediate compatibility with the most common jobsite power tools.
• Multi-Purpose Design Across Material Categories - one hole saw handles wood products, masonry-type materials, and plastics, reducing the number of specialized blades a professional needs to carry on site.

Why This Product

• One tool, many materials - the TCT construction and 6-tooth geometry allow this 5" hole saw to cut cleanly through wood, plywood, MDF, laminates, plasterboard, plastics, bricks, aerated concrete, and soft tiles, consolidating multiple single-purpose blades into a single investment.
• 60mm cutting depth keeps up with real-world wall thicknesses - the generous cutting depth accommodates framing lumber, insulated panels, and double-layer plasterboard installations without requiring the operator to flip or re-approach the workpiece.
• Carbide-grade durability reduces downtime - HW-grade carbide teeth resist wear across abrasive materials like bricks and aerated concrete that would quickly dull standard steel or bi-metal hole saws, keeping the crew productive on long runs of holes.
• Hexagonal shank compatibility with right-hand rotation - the RH hexagonal shank design connects directly to the most widely used drill types on the jobsite, so there is no adapter hunting or compatibility guesswork when switching between drill press work and handheld applications.
