The CMT 694.022.31 2-Piece Adjustable Grooving Set is a professional-grade carbide 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, accurate grooves from 25/32 in. to 1 35/64 in. cutting height - giving woodworkers and production shops the flexibility to tackle varying groove depths without changing tooling. Whether you are working with solid wood, plywood, laminated panels, or composite sheet goods, this two-piece set is built to perform consistently across demanding industrial applications.

Key Features

• 2-Piece Adjustable Cutter Head System - includes 1 cutter head type (A) with Z2 + V2 configuration and 1 cutter head type (B) with Z2 + V2 configuration, plus a spacer rings set, so you can fine-tune groove width to match the exact requirements of each job without purchasing additional tooling.
• Adjustable Cutting Height from 25/32 in. to 1 35/64 in. - accommodates material thickness from 14mm to 39mm deep, making this set versatile enough for furniture components, cabinet joinery, panel grooves, and structural woodworking applications.
• HW (Hardmetal / Tungsten Carbide) Cutting Material - provides the wear resistance and edge retention needed for high-volume production runs, reducing the frequency of blade changes and maintaining groove quality over extended use.
• 4 Teeth and 4 Spurs - the combination of four cutting teeth and four spurs delivers a clean, splinter-free groove entry and exit on solid hardwood, plywood, and laminated panels, reducing tearout and finishing time.
• Operating Speed Range of 4,400 - 7,400 RPM - the defined RPM range allows operators to match the cutter speed to the specific material and machine setup, supporting both safe operation and optimal surface finish quality.
• 1 1/4 in. (31.75mm) Bore Diameter - compatible with standard spindle moulder and shaper machine arbors in this bore size, ensuring a secure, concentric mount for vibration-free cutting.
• Maximum Thickness Capacity of 54mm - handles thicker workpieces that exceed what lighter-duty grooving tools can manage, making this set suited to industrial panel processing and heavy solid-wood applications.
• 6 45/64 in. Cutter Head Diameter - the large-diameter head maintains cutting stability and produces consistent groove geometry even at the upper end of the cutting height range.

Why This Product

• Single set, multiple groove depths - the adjustable design with included spacer rings means one tool covers groove widths across the full 25/32 in. to 1 35/64 in. range, eliminating the need to stock multiple fixed-width grooving heads for different panel or drawer-bottom specifications.
• Engineered for production machines - rated for spindle moulders, double-end tenoners, and shaper machines, this set integrates directly into existing industrial setups rather than requiring a dedicated or specialty machine.
• Broad material compatibility - performs on solid wood, plywood, and laminated panels, so shops processing mixed material types do not need separate tooling for each substrate category.
• Matched RPM range for controlled results - the 4,400 - 7,400 RPM operating window gives operators meaningful control over feed rate and surface quality, reducing the risk of burning on hardwoods or tearout on laminates.
