Straight Cutter Bits

About Straight Cutter Bits

Straight cutter bits are essential router accessories used to create clean, precise grooves, rebates, and slots in wood, engineered boards, and composite materials. These versatile cutting tools feature straight cutting edges that produce flat-bottomed cuts at exact depths, making them indispensable for joinery, cabinet making, and general woodworking applications. MyToolShed.co.uk stocks a comprehensive range of straight cutter bits from leading manufacturers including Trend, Faithfull, Draper, Freud, and Makita.

Available in single flute and two flute configurations, straight router cutters come in various diameters and cutting lengths to suit different routing tasks. Whether you're creating housing joints, trimming laminate, or using worktop jigs, the right straight cutter bit ensures professional results with clean edges and accurate dimensions every time.

Applications

Straight cutter bits are used across multiple trades and applications:

• Joiners and cabinet makers: Housing joints, dado grooves, and rebates for shelving and furniture construction
• Kitchen fitters: Worktop joints, template routing, and post-formed worktop cutting
• Shopfitters: Creating slots for fixtures, display units, and shelving systems
• Carpenters: General grooving, edge trimming, and timber preparation
• DIY enthusiasts: Home improvement projects, furniture restoration, and craft work
• Signmakers: Letter routing and precise depth control for engraving work

Choosing The Right Straight Cutter Bits

Consider these factors when selecting straight cutter bits from MyToolShed.co.uk:

• Shank diameter: Ensure compatibility with your router collet (typically 6mm, 8mm, or 1/4" and 1/2" imperial sizes)
• Cutting diameter: Match the bit width to your intended groove or rebate size
• Cutting length: Choose sufficient depth for your application; longer cutters suit deeper cuts but require more powerful routers
• Flute configuration: Single flute bits provide better chip clearance in deeper cuts, whilst two flute cutters deliver smoother finishes and faster cutting
• Bearing guidance: Template profilers with bearings allow precise pattern routing and edge following
• Material quality: TCT (Tungsten Carbide Tipped) cutters offer superior longevity and maintain sharpness longer than HSS alternatives
• Router power: Ensure your 240v router has adequate power for larger diameter cutters

Safety Information

Always wear appropriate PPE including safety glasses and hearing protection when routing. Ensure workpieces are securely clamped and never attempt freehand routing without proper guides or jigs. Check router bits are correctly installed and tightened before use. Start with shallow passes when cutting deep grooves, increasing depth gradually. Disconnect your 240v router from the mains before changing bits. Inspect cutters regularly for damage or excessive wear, replacing blunt or chipped bits immediately to maintain cut quality and prevent kickback.

Frequently Asked Questions

What's the difference between single and two flute straight cutters?

Single flute cutters have one cutting edge and excel at chip evacuation in deeper cuts, making them ideal for softer materials and plunge cutting. Two flute cutters feature two cutting edges, providing smoother finishes and faster material removal in harder woods and engineered boards.

Can I use straight cutter bits for worktop joints?

Yes, MyToolShed stocks specialist worktop jig router cutters from Trend designed specifically for creating precise joints in kitchen worktops. These feature specific diameters and cutting lengths to work with standard worktop jig systems.

How do I know when to replace my straight cutter bit?

Replace cutters when you notice burning marks on cut edges, increased effort required from your router, rough or torn grain finish, or visible damage to the cutting edges. Regular inspection maintains cutting quality and safety.
