Hinge Cutting Bits

About Hinge Cutting Bits

Hinge cutting bits are precision router accessories designed to create clean, accurate recesses for door and cabinet hinges. These specialised cutters eliminate the time-consuming process of chiselling hinge mortises by hand, delivering professional results in a fraction of the time. MyToolShed.co.uk stocks a comprehensive range including tungsten carbide tipped (TCT) hinge sinking bits for shallow recesses, hinge boring bits for concealed cup hinges, and complete hinge recesser systems suitable for both hand-held routers and router tables.

Available in standard 35mm diameters for concealed hinges and various sizes for traditional butt hinges, these router bits feature different shank sizes to fit most router collets. Premium options include depth stops for precise control, two-flute designs for cleaner cuts, and no-scriber designs that eliminate tear-out. Leading brands at MyToolShed include Trend's CRAFTPRO and professional ranges alongside reliable Faithfull TCT options, all engineered to work with standard router templates and hinge jigs for repeatable accuracy across multiple installations.

Choosing The Right Hinge Cutting Bits

Hinge type and size: Identify whether you need bits for traditional butt hinges or modern concealed cup hinges. Standard 35mm boring bits suit most concealed hinges, whilst butt hinge cutters come in various widths typically between 16mm and 25mm. Measure your hinges before purchasing to ensure compatibility.

Material quality: TCT (tungsten carbide tipped) bits are essential for professional use and maintain sharpness through hundreds of hinge recesses. They handle abrasive materials like MDF and chipboard without dulling, making them cost-effective in the long run compared to basic high-speed steel alternatives.

Shank diameter: Check your router's collet size – most accept 6mm, 8mm or 1/4-inch shanks. Ensure compatibility or have appropriate collet reducers available before ordering from MyToolShed.co.uk.

Features and design: Bits with integrated depth stops provide consistent results and prevent overcutting. Bearing-guided cutters follow templates accurately and produce cleaner edges. No-scriber designs eliminate visible scribe lines on finished work, whilst two-flute configurations offer the best balance between cutting speed and surface finish quality.

Safety Information

Always wear appropriate eye protection and hearing protection when operating routers – noise levels can damage hearing with prolonged exposure. Connect your router to dust extraction equipment where possible, particularly when working with MDF or manufactured boards. Be aware of COSHH regulations regarding wood dust exposure limits.

Secure workpieces properly using clamps or vices before routing. Never attempt to hold small pieces by hand. Ensure router bits are fully inserted into the collet (at least 15mm) and securely tightened before operation. Inspect bits for damage before each use, and never use chipped or cracked cutters. Always allow routers to reach full speed before engaging the workpiece, and never adjust depth or change bits whilst the tool is plugged in.

Frequently Asked Questions

What's the difference between a hinge boring bit and a hinge sinking bit?

A hinge boring bit creates the deeper circular recess (typically 10-13mm deep) needed for concealed cup hinges, whilst a hinge sinking bit creates the shallow recess (3-4mm) for the hinge plate itself or traditional butt hinges. For concealed hinges, you'll often need both types to complete the installation properly.

Can I use hinge cutting bits in a standard power drill?

No, hinge cutting bits are designed exclusively for routers operating at 8,000-24,000 RPM. Using them in a standard drill, which operates at much lower speeds, will produce poor results, potential kickback, and risks damage to both the bit and drill. Always use the correct tool for safety and quality results.

How do I prevent tear-out when routing hinge recesses?

Use sharp TCT bits and ensure your router is running at the correct speed (typically 16,000-20,000 RPM for hinge work). Route in multiple shallow passes rather than one deep cut, and back up the exit edge with scrap material where possible. No-scriber design bits with bearing guides also significantly reduce tear-out issues.
