GUARANTEE & REPAIR SERVICE

We have developed the highest level of expertise in this very special product and we commit ourselves to give you total satisfaction.

All Craftsman Tools centres are 100% guaranteed for 2,000 hours. In the unlikely event of failure within the first 2,000 hours as a result of defects in material or workmanship, we will replace the part. This does not apply to centres which have been modified by the user or another party.

We expect a Craftsman Tools centre to give many years of trouble-free service. From time to time however, due to extreme circumstances, such as machine collisions, a centre will require repair.

Centres will be rebuilt to a ‘like new’ condition at 60% of the cost of a new centre, with a delivery time of around two weeks.

This reconditioning includes:
- New spindle
- New seal
- New bearings
- New lubricant
- Return to original accuracy

If the centre is beyond repair, for any reason, a 25% preferred customer trade-in allowance will be given towards the purchase of an equivalent new centre.
