To comply with current fire regulations, intumescent strips must be fitted to fire check doors or frames to delay the passage of fire between different areas in a building. Although the grooves for the Intumescent strip can be cut with standard twin flute cutters, these bearing guided cutters will make a cleaner cut and the router has a larger support area by working from the face or back of the door. Available with 10mm or 15mm cutting widths and in either 1/4"(6.35mm) or 1/2"(12.7mm) shank sizes.
Axcaliber router cutters are high precision tooling, made using advanced technology on multi axis CNC machines. A high shear-cut angle gives them a smooth cutting action and results in a clean finish. The tips are diamond-ground micrograin tungsten carbide. Teflon coating minimises resin build-up.
