Product Description
CMT Two-Flute Slot Cutter with 1-1/4 in. Diameter and 5/16 in. Bore Compatibility is a precision carbide-tipped routing tool engineered for clean, consistent horizontal groove cutting in solid hardwood, softwood, plywood, MDF, and composite materials. Designed to pair with the CMT 891.517F arbor, this two-tooth slot cutter delivers smooth, controlled passes for biscuit joinery, spline grooves, T-slot channels, and panel joinery work on handheld routers, router tables, and CNC routing machines. The right-hand rotation and hardmetal (HW) carbide construction make it a dependable choice for flooring, inlay, and furniture applications where cut quality and edge consistency matter.
Key Features
- Industrial-Grade Carbide (HW) Cutting Tips - hard metal carbide retains its edge through repeated passes in dense hardwoods and engineered panels, reducing the frequency of sharpening or replacement.
- Two-Flute (Z2) Design - dual cutting edges balance material removal and surface finish, producing clean slot walls while keeping the tool running smoothly through each pass.
- 1-1/4 in. Cutting Diameter - sized to cut precise slot widths suited for splines, biscuits, and T-slot connectors in solid timber, plywood, MDF, and laminates.
- 5/32 in. Cutting Height - a controlled cutting depth allows accurate groove dimensions without over-cutting, keeping joinery tight and consistent.
- 8mm Bore Diameter for Arbor Compatibility - the 8mm bore interfaces directly with the CMT 891.517F arbor (sold separately), ensuring a secure, centered fit that minimizes runout during operation.
- Right-Hand (RH) Rotation - standard right-hand rotation matches conventional router spindle direction, making setup straightforward on handheld routers, router tables, and CNC machines.
- Industrial Quality Construction - built for consistent performance through flooring, inlay, and cabinetry applications where dimensional accuracy across multiple cuts is essential.
Why This Product
- The hardmetal carbide tips stay sharp even after several passes through solid and timber wood, making this slot cutter a practical choice for repetitive production work where edge consistency is critical.
- Designed specifically to pair with the CMT 891.517F arbor, this cutter eliminates compatibility guesswork - the 8mm bore delivers a precise, centered fit for reduced runout and cleaner groove walls.
- The 5/32 in. cutting height and two-flute geometry work together to control chip load, allowing the bit to run smoothly through hardwoods, softwoods, MDF, and laminates without excessive heat buildup.
- With a 1-1/4 in. diameter suited to standard biscuit slots, spline grooves, and T-slot channels, this cutter covers the most common panel joinery tasks in furniture making and flooring installation.
