Service kits are available for these items.  If a tool is worn out or if you happen to lose a piece, individual tools can be easily purchased as replacements. Consumables (bits, blades, impact sockets, etc), and failures due to normal wear and tear or user error, are not covered. Replacement parts are available for purchase, labour related to repairs and servicing is done free of charge.

For best quality of life it is important to keep your tools well maintained. Keep them clean, dry and oiled / lubricated where appropriate. We suggest something like Corrosion Block for lubrication and rust prevention.
