We do sell products that contain moving parts like ratchets & torque wrenches that need to be serviced regularly. Service kits are available for these items. Consumables (bits etc), Impact tools, and failures due to normal wear and tear, 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. IE keep them clean, dry and oiled / lubricated. We suggest something like ACF-50 for lubrication and rust prevention.
