FISCH Wave cutter Forstner bits have been seriously engineered. The bits are forged, before being CNC ground and then hardened meaning; accuracy and sharpness are a premium. The unique Wave cutter design has many benefits compared to a more traditional Forstner. The serrated wave edge generates considerably less heat and allows cutting speeds to be increased with less effort needed to achieve each hole. Metric set includes: 15, 20, 25, 30 and 35mm. Made in Austria. For the best results, use in a pillar drill.

Expensive but cut like a dreamI bought a set of these because all my forstners were blunt and I needed to cut crisp finger holes in industrial tooling chests of drawers. The results were perfect with no break out on the inside surfaces, clean as a whistle. Expensive but recommended for precision quality work.
