The CMT 694.021.31 2-Piece Adjustable Grooving Set is a professional-grade cutter head system engineered for precision slot and groove cutting on a wide range of materials. Designed for use on spindle moulder machines, double-end tenoners, and shaper machines, this adjustable grooving set delivers clean, repeatable results on solid wood, plywood, laminated panels, and more. With a 5-29/32 in. diameter and a 1-1/4 in. bore, the set accommodates groove depths from 14mm to 39mm, giving woodworking professionals the flexibility to handle diverse production demands without changing tools.

Key Features

• 2-piece adjustable cutter head design - includes one Type A head (Z2 + V2) and one Type B head (Z2 + V2), allowing the operator to dial in the exact groove width needed for each application without purchasing separate fixed-width tooling.
• Cutting height range of 9/16 in. - 1-1/16 in. - supports groove depths from 14mm to 39mm, giving this set the versatility to handle everything from shallow dados to deeper structural grooves in a single setup.
• HW (carbide) cutting material - hard-wearing tungsten carbide maintains a sharp edge longer than standard high-speed steel, reducing downtime for tool changes and keeping production moving at full speed.
• 4 teeth and 4 spurs - the multi-tooth, multi-spur configuration promotes balanced cutting forces and a smooth surface finish, minimizing tear-out on solid hardwood, plywood, and laminated panels.
• Operating speed range of 5000-8000 RPM - matches the output of professional spindle moulder machines and double-end tenoners, allowing safe, efficient use in industrial production environments.
• Spacer rings set included - the included spacers make it straightforward to fine-tune the groove width precisely, eliminating guesswork and reducing setup time between production runs.
• Maximum workpiece thickness of 44mm - accommodates thick solid-wood panels and engineered lumber, expanding the range of projects this grooving set can handle in a shop or production facility.

Why This Product

• The adjustable two-piece configuration covers groove widths across a wide range without requiring separate fixed-width heads - ideal for shops that produce multiple groove sizes on the same production day.
• Compatibility with spindle moulder machines, double-end tenoners, and shaper machines means this grooving set integrates directly into professional woodworking production lines without requiring specialized or proprietary machinery.
• The HW carbide cutting material paired with 4 spurs delivers clean entry and exit cuts on solid wood, plywood, and laminated panels - reducing the sanding and finishing time needed after grooving operations.
• The included spacer ring set provides immediate, out-of-the-box flexibility to adjust groove width accurately, making this a complete solution rather than a starter tool requiring additional accessories before it can be put to work.
