Cutting tool e.g. drill bit for processing workpiece e.g. timber material, has metal foamed main portion with open cell wall comprising pores for removing cut material during geometric indefinite cutting of workpiece

The cutting tool has metal foamed main portion (1) with open cell wall (9) comprising pores (8) for removing cut material during geometric indefinite cutting of workpiece. The metal foamed main portion is rotationally symmetric, and is comprised of particles for amplification, lubrication, and/or refrigeration. The pores are formed as chip receivers, and are cured with polishing paste or wax to infiltrate the cut material.
