Product Description
CMT Two-Flute Slot Cutter with 1 1/8" Diameter and 5/16" Bore is a precision carbide-tipped slotting blade engineered for clean, consistent groove cutting in solid hardwood, softwood, plywood, MDF, and composite sheet goods. Designed to pair with the CMT 891.512F arbor, this two-flute cutter delivers smooth horizontal slots for biscuit joinery, spline grooves, T-slot tracks, and panel assembly applications. With a compact 1/4" cutting height and right-hand rotation, it integrates seamlessly into handheld router and router table setups where accuracy and repeatable results are essential.
Key Features
- Two-Flute Carbide-Tipped Design (HW Material) - hard tungsten carbide tips maintain a sharp cutting edge through repeated passes in solid timber and engineered wood, reducing downtime from frequent blade changes.
- 1/4" Cutting Height - produces a precise, consistent slot depth ideal for standard biscuit, spline, and T-slot connector profiles without overcut risk.
- 1 9/64" Blade Diameter - sized for accurate slot placement in a wide variety of joinery and inlay applications, giving the operator control over slot position relative to the workpiece edge.
- 8mm Bore Diameter - machined to close tolerances for a secure, wobble-free fit on compatible arbors, directly contributing to slot accuracy and surface finish quality.
- Right-Hand Rotation - matches standard router spindle direction, allowing straightforward setup on handheld routers, router tables, and CNC routing machines without additional configuration.
- Industrial Quality Construction - built for flooring, inlay, and panel joinery production environments where the cutter must run smoothly through solid and timber wood and stay sharp even after several passes.
- Compatible with CMT 891.512F Arbor - purpose-matched to the CMT arbor system, eliminating compatibility guesswork and ensuring the cutter runs true at operating speed.
Why This Product
- If you need a dedicated slotting blade for biscuit joinery, spline routing, or T-slot work, the two-flute carbide design stays sharp across multiple passes in both solid hardwood and engineered panels - reducing the need to stop and swap tooling mid-project.
- The 8mm bore and 1 9/64" diameter are precision-matched to the CMT 891.512F arbor, so the cutter runs without vibration or runout - directly improving slot consistency and edge quality in flooring and inlay work.
- With a 1/4" cutting height optimized for standard joinery profiles, this cutter handles the most common slot depths used in panel assembly and cabinet work without requiring multiple setup adjustments.
- Industrial-grade carbide tipping and right-hand rotation make this blade a practical choice for both jobsite handheld routers and stationary router tables, covering a broad range of wood species and sheet materials in one tool.

Frequently Asked Questions
What arbor is this slot cutter designed to work with?
This cutter is designed for use with the CMT 891.512F arbor. The 8mm bore is precision-matched to that arbor for a secure, concentric fit that keeps the cutter running true during operation.
What slot depth does this cutter produce?
The cutting height is 1/4", which is the working depth of the slot produced in a single pass. This dimension is suited for standard biscuit, spline, and T-slot connector profiles used in panel joinery and cabinetry.
What types of wood and materials can this cutter handle?
The industrial carbide-tipped two-flute design is built to run through solid hardwood, softwood, plywood, MDF, chipboard, laminates, melamine, and plastic. The carbide edge stays sharp even after several passes through dense or engineered materials.
Can this slot cutter be used on a router table as well as a handheld router?
Yes. The right-hand rotation and standard arbor-mount design make this cutter compatible with handheld routers, router tables, and CNC routing machines - giving flexibility for both shop and jobsite use.
