Need a 2 1/2 hole in street curb for drainage pipe, curb 6 - 6 1/2 inches thick, have Dewalt dwe4011 angle grinder w/ 5/8"-11 spindle, will this do it

The grinder can't give you an option to slow down the RPM unless you have a variable speed grinder. Drilling on concrete, you must use a slow gear of about 250 rpm or less so a grinder might not be the best option unless you don't have any drill and you enjoy melting the core bit or worse hurting yourself. Or maybe you can slow down the grinder if you put an inline high wattage dimmer switch (bad idea) or use a Variac “Voltage Regulating Transformer” and make sure it is an isolated AC transformer such as the “10 Amp Variac Variable Transformer with Isolation, 1000va Max, 0~130 Volt Output”. For a lab, there is a dedicated lab-grade variable or regulated high-voltage power supply. Without isolation, oscilloscope probing can be dangerous, as the BNC connector sheaths are shorted to mains earth. Careful because typical AC motors would require variable frequency drive. Lowering the voltage on a typical motor only increases the current, which leads to overheating and burnout. People say this is only for reducing AC voltage applications; for controlling AC motor you will need 3 phase motor controller. They spin between 2,800 to 10,000 rpm and the lowest setting is still too fast for drilling into concrete. It should be around 150 rpm and maximum 250 rpm. In conclusion I absolutely don’t advise on using an angle grinder. It is a very bad idea. Regarding buying a variable angle grinder, it is still too fast and I don’t advise that either. Besides, you face is too close to the project and the tool design will not have stability. Very unsafe. In the oil and gas industry, they use a maximum of 250 RPM when they drill cores into rocks.

Have dewalt spline hammer drill & a sds adapter for small bits & hd milwaukee right angle drill which to use for 8" concrete?

I ran it on a Dewalt 1/2” angle drill at low speed. If possible use a little water, keep it good and straight.

I have an dewalt sds plus rotary hammer drill what attachment do i need to make this work?

Hi, we have a SDS-plus core bit with pilot bit here: https://www.amazon.com/dp/B077WR36NY Please remember to turn off hammer mode when using a core bit.
