Biscuit Jointers

About Biscuit Jointers

Biscuit jointers are specialised woodworking power tools that create strong, accurate joints by cutting crescent-shaped slots into timber edges. These slots accommodate compressed beech wood biscuits which, when glued, swell to form incredibly robust connections ideal for cabinet making, worktop installation, and furniture construction. MyToolShed.co.uk stocks both traditional biscuit jointers from leading brands including Makita, DeWalt, Bosch Professional, and Draper, plus innovative Festool Domino systems that use rectangular tenons for even greater strength and versatility.

Available in corded 240v models for consistent workshop power and cordless 18v versions offering complete site portability, modern biscuit jointers range from budget-friendly options for DIY enthusiasts to professional-grade brushless motor tools built for daily trade use. Whether working with solid hardwoods, softwoods, or sheet materials like MDF and plywood, these precision tools deliver consistently superior results compared to dowel joints or simple butt joints.

Applications

Biscuit jointers are essential tools for a wide range of woodworking professionals and applications:

• Cabinet Makers and Kitchen Fitters: Assembling carcasses, face frames, and creating invisible worktop joints
• Joiners and Chippies: On-site door and window frame construction, skirting joints, and general carpentry
• Furniture Makers: Creating strong joints in tables, chairs, wardrobes, and bespoke furniture pieces
• Shopfitters: Retail display units, shelving systems, and commercial joinery installations
• Woodworking Hobbyists: Home workshop projects requiring professional-quality joints without complex traditional joinery skills
• DIY Enthusiasts: Built-in wardrobes, shelving units, and general home improvement projects

Choosing The Right Biscuit Jointers

Power Source: Corded 240v models offer unlimited runtime and consistent power ideal for workshop use, whilst cordless 18v versions provide excellent portability for site work. Consider your existing battery platform when choosing cordless options from Makita, DeWalt, or Bosch.

Motor Type: Brushless motors in premium models deliver superior efficiency, longer runtime, and extended lifespan. Budget-friendly brushed motor options from Einhell and Draper suit occasional DIY use perfectly well.

Blade and Adjustment Features: Standard 100mm blades with adjustable plunge depths accommodate all three biscuit sizes (0, 10, 20). Look for robust fences with clear angle markings and positive stops at common angles for precise mitre and corner joints.

Dust Extraction: Quality dust extraction ports compatible with workshop vacuum systems maintain healthier working environments and comply with HSE regulations, particularly when cutting MDF and manufactured boards.

Build Quality: Professional tradespeople should invest in robust models with metal housings and precision-machined fences. MyToolShed.co.uk stocks everything from Festool's premium Domino systems to reliable entry-level choices for lighter duty work.

Safety Information

Always secure workpieces firmly before cutting—never attempt to cut hand-held pieces as unexpected movement can cause dangerous kickback. Wear respiratory protection rated at least FFP2, particularly when cutting MDF or manufactured boards, as fine dust presents serious health risks under COSHH regulations. Connect to HSE-compliant dust extraction systems whenever possible and work in well-ventilated areas.

Wear safety glasses to protect against flying debris and hearing protection for extended use. Disconnect power or remove batteries before changing blades or clearing blockages. Allow blades to reach full speed before plunging and stop completely before withdrawing from cuts. Use RCD protection with all 240v corded tools to prevent electric shock.

Frequently Asked Questions

What's the difference between a traditional biscuit jointer and a Festool Domino?

Traditional biscuit jointers cut crescent-shaped slots for oval compressed beech biscuits, whilst Festool's Domino system cuts rectangular mortises for loose tenons. Domino joints are significantly stronger and allow adjustable positioning even after initial assembly, but represent a considerable investment. Traditional biscuit jointers offer excellent value for cabinet and panel work where their joint strength is perfectly adequate.

Can I use a biscuit jointer on MDF and plywood?

Absolutely. Biscuit jointers work excellently on sheet materials including MDF, plywood, and chipboard. Biscuit joints are often superior to other methods for these materials as they don't require the edge density needed for screws. Always use dust extraction when cutting manufactured boards due to health risks under COSHH regulations.

Do I need a corded or cordless biscuit jointer?

Corded 240v models offer unlimited runtime and consistent power ideal for workshop-based furniture making. Cordless 18v models provide freedom of movement perfect for kitchen fitters and site work where dragging cables is impractical. If you already own 18v batteries from major brands, a cordless model in the same platform offers excellent value.
