Please note: While the Contractor Pro Series Core Bits are economical core drill bits for most general purpose applications, we do not recommend these core bits for certain jobs. For example, if you know you are drilling through asphalt, the Contractor Pro Series Core Bits will core fairly quickly. However since asphalt is more abrasive than concrete, the core bits will not last as long as you might like.
Additionally, if you know you’re drilling through high PSI concrete or concrete with hard aggregate, then we’d recommend choosing our Superior or Professional brand concrete core bits because they are designed for those applications. Remember matching the right concrete core bit to your application will save you time. And time is money, so let’s get your the right core bits for your job.
