Very similar to other grades of mild steel, tool steel is generally shiny in appearance and slightly darker than aluminum alloys. For corrosion resistance, black oxide can be applied post-machining. To achieve a variety of surface finishes, tool steel parts can also be media blasted or tumbled.
Min Wall Thickness | Min End Mill Size | Min Drill Size | Max Part Size | Undercuts | Radii : Depth |
|---|---|---|---|---|---|
0.5 mm | 0.8 mm (0.03 in) | 0.5 mm (0.02 in) | 1200 x 500 x 152 mm [x,y,z] (mill) 152 x 394 mm [d,h] (lathe) | Square profile, full radius, dovetail profiles | Depth must not exceed 12x drill bit diameter. For end mills, depth must not exceed 10x tool diameter. |
Cost Saving Tip
To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
