I had to drill into some concrete to
reinforce a handrail on Friday.
Needed a 5/32 SDS bit for my drill.
There was a Menards just a couple of miles
away so I went and bought 2 of them.
The first one twisted off but I was lucky
and was able to pry it out.
I put the second one in and drilled a dozen
holes with it.
When I went to remove the bit from the
drill it would not come out. I had to put
vise grips on the bit and tap it out with a
hammer.
Looked closer at it when I got home and can
see the steel around the keyway is soft has
deformed just enough to increase the
diameter of the drill shank so it wouldn't
pull out.
These bits were an off brand.
Home Depot sells Bosch SDS bits. I will go
back to buying those.
