The CMT Plug Cutter - 3/4" Plug Diameter, 1/2" Shank is a precision-ground wood plug cutting tool engineered for craftsmen who need clean, grain-matched plugs to conceal screw heads and fill counterbored holes in natural softwoods and medium-density woods. Built from SP steel for long-lasting cutter performance, this right-hand rotation plug cutter features 4 cutting edges that shear smooth-sided cylindrical plugs with consistent diameter, making it a reliable choice for cabinet making, furniture construction, and finish carpentry work where concealed fasteners are a priority.

Key Features

• 4 Cutting Edges - four shearing edges work together to produce clean-sided cylindrical plugs with consistent walls, reducing tearout and delivering plugs that seat flush and grain-match the workpiece when oriented correctly.
• SP Steel Construction - high-strength special-purpose steel body provides long-lasting cutter performance, meaning fewer tool changes and more consistent plug quality over the life of the cutter.
• 3/4" Plug Diameter with 1-7/32" Outer Diameter - the outer diameter clears a relief channel around the plug as it cuts, allowing the finished plug to be broken free cleanly without crushing or distorting the plug walls.
• 1/2" Shank - the 1/2" shank provides a secure, low-runout connection in a standard drill press chuck, keeping the cutter centered and the plug diameter accurate from cut to cut.
• 5-1/2" Total Length - the extended overall length gives the cutter enough reach to produce plugs at full depth while keeping the shank well engaged in the chuck for stability during the cut.
• Right-Hand Rotation (RH) - designed for standard right-hand drill press spindle rotation, compatible with the vast majority of drill press machines without any special setup.

Why This Product

• When screw heads need to disappear completely, this plug cutter produces grain-matched wood plugs from the same board as the workpiece, resulting in a virtually invisible repair in natural softwoods and medium-density woods.
• The SP steel body is purpose-built for long-lasting cutter performance, making this an economical choice for shops and craftsmen who cut plugs regularly rather than relying on disposable or low-grade alternatives.
• With a 1/2" shank and 5-1/2" total length, this cutter is sized to work securely in the drill press setups most commonly found in woodworking shops, with no adapters or special tooling required.
• The 4-edge cutting geometry produces plugs with clean, consistent sidewalls, which means the plugs glue up tightly in counterbored holes and sand flush with minimal cleanup - saving time on finishing steps in cabinet and furniture work.
