The CMT 694.001.31 3-Piece Adjustable Grooving Set is a professional-grade dado and slotting solution engineered for spindle moulders, double-end tenoners, and shaper machines. With a 5 1/2 in. diameter and 1 1/4 in. bore, this carbide-tipped grooving set delivers precise, clean slots and grooves at depths ranging from 5/32 in. to 19/32 in., making it the go-to choice for woodworking shops working with solid wood, plywood, and laminated panels. The included spacer rings allow fine-tuned groove width adjustment, so operators can dial in the exact cut without switching tools.

Key Features

• 3-piece adjustable configuration - two Type A cutter heads (each with 4 teeth and 4 spurs) plus one Type B cutter head (2 teeth) combine to cover a wide range of groove widths in a single setup, reducing tool changeover time on the shop floor.
• 12 included spacer rings ranging from 0.1 mm to 2 mm - allows micro-adjustment of groove width so you achieve an exact, tight-fitting slot every time without secondary cleanup passes.
• Cutting height range of 5/32 in. to 19/32 in. - accommodates grooves from 4 mm to 15 mm deep, covering the most common joinery and panel-slotting applications in a single set.
• 5 1/2 in. diameter with 1 1/4 in. bore - sized for industrial spindle moulders, double-end tenoners, and heavy-duty shaper machines, providing stability and reduced vibration at operating speeds.
• HW (carbide) cutting material - hard metal carbide tipped cutters retain sharpness through demanding production runs on hardwood, softwood, plywood, and laminated panels, extending time between sharpenings.
• Operating speed range of 5,500 - 9,500 RPM - broad RPM compatibility suits a variety of industrial machine configurations without requiring special spindle speed modifications.
• 4 spurs per Type A head - scoring spurs pre-score the material surface before the main cutters engage, dramatically reducing tear-out and edge chipping on laminates and finished panels.
• Ideal for solid wood, plywood, and laminated panels - the geometry and carbide grade are matched to the grain structures and glue lines found in these common workshop materials, producing clean, splinter-free groove walls.

Why This Product

• Shops that cut grooves and dados at multiple widths no longer need a separate cutter for each dimension - the 12-piece spacer ring system and 3-head configuration make this set a single-purchase solution for slots and grooves from 4 mm to 15 mm deep.
• The combination of Type A heads (with scoring spurs) and the adjustable Type B head means you get tear-out-free results on both face-side and edge-side cuts on laminated panels and plywood - materials that typically chip with standard grooving cutters.
• With a maximum operating speed of 9,500 RPM and a minimum of 5,500 RPM, this grooving set is compatible with a broad range of spindle moulder and double-end tenoner machine models, making it a flexible addition to a production environment with multiple machines.
• The hardened carbide (HW) cutting edges are matched to the heavy-duty demands of production joinery work, meaning longer intervals between tool reconditioning and lower total cost of ownership over the tool's service life.
