Warranty claims will occur on less than 1/2 of 1% of the Simpson Strong-Tie Anchor Systems® carbide-tipped bits used. This estimate is based on experience with many millions of bits in various tools and materials.
The following information has been produced to enable you to improve your ability to fairly determine defects. BITS ARE WARRANTED FOR REPLACEMENT ONLY AND IN NO CIRCUMSTANCES WILL SIMPSON BE LIABLE FOR MERCHANTABILITY OR LOSS OF SERVICE.
If the defect is not obvious, please return the bit to our home office in Pleasanton, CA. Warranty decisions will be made within 48 hours after receiving the returned item(s).
Carbide fracture can be caused by two primary reasons: hitting an extremely hard foreign object in the concrete or hitting and staying on reinforcing steel. Steel strikes are readily identifiable. The bit steel will be damaged as well as the tip itself. The operator should cease hole production when the bit stops turning and start a new hole. Bits damaged due to steel strikes are not warranted.
If the break area shows jagged steel and no notch, the bit has been over-torqued by jamming in the hole. The bit is not covered by warranty.
This is a positive indication that the bit has been used to produce deeper holes than it should. This means that debris has not been able to clear the hole readily, producing excessive heat buildup, which destroyed the bit—no warranty replacement. (User should purchase longer bits or use a lighter-duty hammer with small diameter bits).
This indicates the hammer tool holder should be repaired or replaced—no warranty replacement.
