Replaceable Blade Router Cutters
These are precision ground cutter spindles onto which you can fit removable solid tungsten carbide blades. The blades are held in place with small screws and each one is ground on two or four of their cutting edges, so you can quickly turn them round to expose a new cutting edge after the first has dulled down.
The advantages are obvious, particularly in a production set-up where the blades can be replaced without disturbing the router or depth settings, therefore minimising expensive downtime.
The blades are relatively cheap as well, so the economic advantages are enormous, particularly with very abrasive materials that quickly dull the edge. However, they are only available in straight and angled profiles and some are not suitable for plunge cutting.
Mlti-Profile Replaceable Blade Router Cutters
This system allows you to fit a variety of different profiled solid carbide blades into a holder that is available with and without a bearing guide. Two blades are fitted to the body and they are designed to provide integral chip limitation to minimise kickback.
As no brazing is required, a higher grade of tungsten carbide can be used, resulting in superior edge holding and durability.
The blade range includes a good selection of decorative profiles, making it a very economical option for the home user needing quality cutters at minimal cost, when the small amount of down time involved in changing over the blades is unimportant.
