Bosch HC8526 2-5/8 in. x 17 in. SDS-MAX Rotary Hammer Core Bit
- Bosch SDS-max rotary hammer core bits are carbide tipped with an integral shank for better power transmission
- Core bits go beyond the range of standard bits and allow smaller hammers to drill larger holes
- Maximum core size is 4 in. deep
- 2-5/8 in. x 17 in. SDS-max Rotary Hammer Core Bit - HC8526
The negative is that the core bit central chamber that collects the concrete core is prone to get the concrete chunks stuck in it.
A beter design would include an easily removable centering pin so that after the hole is started the pin would come out because it is no longer needed, and and then the scrap concrete would have one less thing to bind up on and be easier to remove.
I have only made about 6 holes with it so far but I am glad I bought it.
