The CMT Plug Cutter 7/8" (529.222.31) is a precision-engineered plug cutting tool designed to drill clean, cylindrical wood plugs from natural softwoods and medium-density woods. Built from SP steel for long-lasting cutter performance, this right-hand rotation plug cutter features a 1/2" shank and 5 cutting edges that produce tight, grain-matchable plugs - perfect for concealing screw heads, filling counterbored holes, and achieving seamless results in cabinetry and furniture work.

Key Features

• SP Steel Construction - super-strength steel body delivers long-lasting cutter performance, reducing tool wear and extending the life of the cutter through repeated use in woodworking applications.
• 5 Cutting Edges - more cutting edges mean cleaner, smoother-sided cylindrical plugs with less tear-out, allowing grain-matched plugs that blend naturally into the workpiece surface.
• 7/8" Plug Diameter - produces consistent 7/8" diameter plugs that fit standard counterbored holes precisely, eliminating gaps and ensuring a flush, professional finish when concealing fasteners.
• 1/2" Shank - the 1/2" shank provides secure, stable chucking in drill press spindles, reducing vibration and contributing to accurate, controlled plug cutting every time.
• Right-Hand Rotation - standard RH rotation matches the drive direction of conventional drill press equipment, ensuring compatibility with typical woodworking setups without any special configuration.
• 1-11/32" Outer Diameter and 5 1/2" Total Length - the generous total length allows the cutter to reach full plug depth in a single pass, making the workflow efficient and consistent across repeated cuts.
• Optimized for Natural Soft and Medium-Density Woods - purpose-built material compatibility means the cutter geometry is tuned to the grain structure of softwoods and medium-density lumber, producing plugs that seat cleanly and sand flush.

Why This Product

• Woodworkers who need to hide screw heads or fill counterbored holes with matching wood plugs will benefit from the 7/8" cutting diameter and 5-edge geometry, which produces plugs with clean sidewalls that lock tightly into the corresponding bore.
• The SP steel body is formulated for long-lasting cutter performance, meaning the tool maintains its cutting edge through repeated plug-cutting sessions in natural softwood and medium-density wood projects without premature dulling.
• With a 5 1/2" total length and 1/2" shank, this plug cutter offers the reach and rigidity needed to cut full-depth plugs in a drill press with consistent diameter and straight sidewalls - every cut, every time.
• Cabinet makers and furniture builders working with natural softwoods or medium-density materials gain a dedicated cutting tool matched to those specific wood types, rather than a general-purpose cutter that may tear or splinter softer grain structures.
