Common case types include plastic storage boxes or molded plastic cases, molded plastic racking/shelves, compact carrying cases, and roll-up canvas organizers for tool storage.
Most cases are made from plastic (from lightweight to sturdy molded plastics and plastic racking). Some kits use stitched canvas roll-up organizers for storage.
Portability features include compact case designs, lightweight plastic toolbox-style or small storage boxes, and roll-up canvas cases that keep tools tidy and easy to transport.
Many sets use S2 alloy steel bits and include magnetic bits or magnetic adapters to help hold bits securely during use.
Noted ergonomic features include non-slip handles such as T-handles, TPR (thermoplastic rubber) grips, and aluminum-alloy T-handles for improved comfort and easier use.
