The Klein Tools warranty covers defects in materials and workmanship over the entire life of the product. At the company's discretion, it may repair, replace or refund any product which fails to live up to the warranty. There is no implied warranty of an item's merchantability or fitness. This general warranty excludes electronic test and measurement products, which have their own warranty, and ratcheting and drill-operated cord cutters, which are warranted for one year from the date of purchase.
The Klein Tools warranty begins as soon as a customer purchases a product, and covers items such as drill bits, disposable razor and knife blades, Klein chemicals, hand cleaners and replaceable cutting inserts. All defective items must be returned accompanied by a warranty return authorization number, available from the company via telephone or email. Klein denies liability for any incidental or consequential damage caused by its products. No implied warranty may last longer than five years. State law may overrule some of the warranty's stated limitations.
Klein electronic and measurement devices and accessories are warranted to be free from defects in workmanship and materials for two years from the purchase date. This does not include batteries. The MM5000 and MM6000 are covered for five years from the purchase date, unless the packaging notes otherwise. The Klein Stubby Mug and Insulated Beverage Hauler are also covered for five years from the original purchase date, given normal use. Like the general warranty, Klein may replace, repair or refund any product found wanting, and there is no implied warranty of merchantability or fitness.
Cordomatic-branded products are warranted for materials and workmanship for six months after the original purchase date, and the company may repair or replace any defective product at no cost to the customer. As of 2015, Klein no longer offers grip repairs.
