Cutting Tools

High-speed steel cutting tools are adequate for most machining applications. Carbide and other harder tools have also been used successfully in industrial applications. The more expensive, higher speed tools permit higher cutting speeds and can be justified in large production runs on machines that can develop the higher speeds.

Moderate-to-high feed rates and cutting speeds can be used. Dwells in feed rate should be avoided, as they rapidly generate heat through friction and lead to galling, burr formation and surface finish deterioration. Sharp cutting edges should be maintained to reduce heat generation, galling, burr formation, and dimensional variations.

Fluted tools such as drills, taps, reamers and end mills should have large, polished flutes to reduce friction and help remove chips from the cutting edges. Ground and polished rake and flank faces generally provide better results.

Rigidity in the tool and work piece mounting are important to achieve the desired dimensional accuracy and surface finish.
