i had to drill out a hardened bolt and went through a whole bunch ‘o’ bits. here are the 4 types of bits i used

coming in first place: IRWIN they lasted much longer than the others and stayed more sharp

2nd ace hardware

3rd craftsman professional

4th ridgid home depot brand the ridgid bits were absolute garbage

i hope this helps anyone in the future
