Product Overview
The Star Blue is a good value for basic coring. It uses good quality diamonds for moderate cutting life. It is meant to be used on block and soft brick. Do not use this on concrete or rebar.
Core travel is 9", thread size is 5/8"-11.
Use wet or dry.
Dry Core Bits can be used with hammer drills provided you have: 1) the correct adapter and 2) a setting on your drill for spin only (the hammer action will blow the diamonds right off the bit, making it useless).
