How many holes can I drill into concrete using a Relton bit?
This will vary dependent on many factors. The PSI of the concrete will be a factor, along with the hardness of the aggregate in concrete. Aggregate hardness varies from locale to locale (even in the same state!). Florida has some of the softest aggregate, while Louisiana has some of the hardest. See the Aggregate Map of the United States for details. Other factors that need to be considered are operating conditions and the type and style of the bit being used.
