Cutting Tool Selection for 50 Material Entries

In modern manufacturing, choosing the right tool is key to ensuring product quality and productivity. However, even “industry veterans” are often at a loss when faced with a wide range of materials and machining requirements. To solve this problem, we’ve put together a guide to machining tools for 50 common materials.

Aluminum alloy is an alloy formed by taking aluminum as the main component and adding other elements (such as copper, magnesium, silicon, zinc, manganese, etc.). Due to its excellent performance, it is widely used in many fields such as aviation, automotive, construction, packaging and so on.

Material characteristics: lightweight, high strength, corrosion resistance, good processability, good electrical and thermal conductivity.

Tool options: sharp high-speed steel (HSS) tools or carbide cutting tools for suitable operations; PCD (polycrystalline diamond) tools or diamond-coated tools may suit abrasive aluminium alloys. PCD is a sintered cutting material, not another name for a diamond coating. Select the grade and geometry for the actual alloy and operation.

Stainless steel is a steel alloy containing not less than 10.5% chromium and is highly resistant to corrosion. It is widely used in construction, medical equipment, kitchen utensils and chemical equipment.

Material characteristics: corrosion resistance and mechanical properties depend on the stainless grade and condition. Machinability, work hardening, heat resistance, and weldability differ across austenitic, ferritic, martensitic, and duplex grades.

Tool options: carbide grades and chip-control geometries intended for the actual stainless group. Choose a qualified coating, such as a suitable PVD or CVD system, for the operation rather than assuming TiN or TiCN is always preferred.

Titanium alloys are alloys composed of titanium and other elements (e.g., aluminum, vanadium) and are widely used in the aerospace, medical and chemical industries because of their high strength, light weight and excellent corrosion resistance.

Material characteristics: high strength, low density, corrosion resistance, high temperature resistance, low modulus of elasticity.

Tool options: sharp, tough carbide grades and geometries qualified for titanium. Control heat, adhesion, chip evacuation, and tool engagement. Ceramic tools are not a general-purpose recommendation for titanium; use only a specifically validated tool and process.

Heat treatment changes steel structure and properties. Quenching and tempering are common routes, but annealed, hardened, and other conditions require different tooling. Identify the actual grade, treatment, and hardness before selecting a cutting tool.

Material characteristics: hardness, strength, ductility, and wear resistance depend on the steel grade and heat-treatment condition; annealing may reduce hardness rather than increase it.

Tool options: carbide for suitable conditions, or qualified CBN, ceramic, or grinding processes for harder finishing applications. Choose by actual hardness, cut type, and surface requirements rather than the label heat-treated alone.
