Safety and Compliance

Router bits operate at extremely high rotational speeds and must be treated with appropriate respect. Always ensure bits are securely tightened in the router collet before operation, checking shank engagement extends at least 19mm into the collet. Inspect cutting edges before each use for chips, cracks or excessive wear that could cause dangerous failure during operation.

Always use appropriate personal protective equipment including safety glasses, hearing protection and dust masks when routing. The fine dust produced during routing operations presents respiratory hazards covered under COSHH regulations, requiring appropriate extraction or respiratory protection. Never exceed the manufacturer's recommended maximum speed for the bit diameter being used—larger diameter bits must rotate more slowly to keep rim speed within safe parameters.

Ensure workpieces are securely clamped and never attempt to rout freehand without proper guides or templates. Feed direction matters significantly; always feed against the rotation direction of the bit to maintain control. Following HSE guidance for woodworking machinery operation protects both operator and workshop colleagues from preventable accidents.

Frequently Asked Questions

What's the difference between cove and cavetto router bits?

Whilst both create concave profiles, cove bits typically produce a simple radiused curve, whilst cavetto bits create the specific quarter-round concave profile (quarter-circle) used in classical moulding work. Cavetto profiles have a more defined geometric appearance suitable for architectural applications, whilst cove bits offer more varied curve options for general decorative work.

How long do Draper carbide router bits typically last?

With proper use and maintenance, Draper carbide-tipped bits can profile several hundred linear metres of hardwood before requiring sharpening or replacement. Actual lifespan depends on material hardness, feed rates, routing speed and whether proper dust extraction is used. Abrasive materials like MDF and chipboard reduce cutting edge life more rapidly than solid timber.

Can these bits be used in both plunge routers and router tables?

Yes, Draper radius, cove and cavetto bits work effectively in both handheld routers and inverted router table configurations. Router tables often provide better control for edge profiling work, allowing consistent feed rates and more stable workpiece support, particularly important when routing narrow or small components where maintaining consistent bearing contact is challenging.

What routing speed should I use with profile bits?

Generally, larger diameter bits require slower speeds whilst smaller bits can safely run faster. For radius, cove and cavetto bits up to 25mm diameter, speeds of 18,000-22,000 RPM work well in most timbers. Larger bits may require reduction to 12,000-16,000 RPM. Always start conservatively and make multiple shallow passes rather than attempting to remove excessive material in a single pass, which risks burning and bit damage.

Do Draper router bits come with bearing guides?

Many Draper profile bits include bearing guides that ride against the workpiece edge, allowing template-free edge profiling with consistent results. The bearing diameter determines how much of the profile is cut versus left as a shoulder. Check individual product specifications as some bits are designed for use with separate guide bushes or router table fences rather than integral bearings.
