> Drill Bits



This custom drill bit can be used with our patented Dor-Cor Drilling Tool (door core drill fixture), or used separately if you need a long drill bit to drill the width of a door. We don't recommend that you use this on fire rated doors. You can use it on listed doors, so long as you are a certified person under the Perfect Raceway Program. The PRP is managed by Intertek Testing Services, under the Warnock Hersey name brand. If you need a replacement bit for your Dor-Cor, or you are just looking for a very well made custom door drilling bit, this is the one you want to order. 


It is recommended that all customers check the drill bits before signing for them. Since UPS has a reputation for bending this item please refuse the package if it is damaged in any way. This will start the claim process and we will send out new replacement drill bits as soon as we are notified.

As per Marray's terms and conditions of sale, If a customer fails to check the drill bits before signing for them and fails to notify Marray of the damage within 30 days Marray is no longer responsible for replacing the damaged item. The customer will then have to file a claim with UPS and purchase new drill bits from Marray.
