Spiral Router Cutters

Spiral router cutters are ones that have flutes that wind around their body in a helical shape and are designed to produce flat-bottomed grooves for a wide range of different applications. This particular range of spiral router bits is made of Solid Tungsten Carbide but there is also a selection of spiral cutters that can be found in the Professional HSS and TCT ranges. Spiral cutters have certain advantages over straight ones due to the shape of the flutes. They are more efficient at expelling any waste material and debris as it is cut due to their helical flutes that run right around their body, this helps to prevent the bit from becoming clogged. They produce smoother cuts than standard straight cutters due to their shearing motion rather than chipping motion. The smoother cutting action of a spiral bit means it is less likely to vibrate as it cuts.
