Create clean grooves and accurate template-guided cut-outs in solid wood with the Festool HS Spi S8 D8/19 spiral groove cutter. Particularly suited to softwood, its high-speed steel cutting edges deliver a smooth cutting action, while the spiral geometry reduces cutting pressure and carries chips upwards out of the cut. This helps keep the groove clear and supports effective chip extraction. With an 8 mm cutting diameter and 19 mm cutting length, this cutter is a practical choice for furniture components, joinery details and guided routing work where controlled cutting and clean results matter. HS spiral cutting performance for solid wood The HS cutting material is high-speed steel, selected for its suitability for solid wood and especially softwood. The right-hand spiral produces a drawing cut that reduces cutting pressure, while the base cutting blade allows plunge entry when used with a suitable plunge router and a controlled cutting technique.
