HSS is good for wood IMHO, but not so good for steel.

Vash - I used a Dremel grinding bit to "initiate" the hole - works great for that and the cone shape creates a nice funnel shaped entry. But they can only go so deep... and the deeper they are, the more likely they are to break...

I bought the Rigid cobalt bits. Home Despot also have Ti coated, and something else. The other two brands were DeWalt and Bosch or another good brand name. As usual, the sales clerk knew nothing at all about his wares. OTOH, I paid nothing at all either. My credit card points can be transmogrified into HD gift cards so I used that. The Rigid bits came in a nice case and the whole thing was clearance saled down to $20.

They worked - I put in another hour drilling and none of the bits broke off. I was then able to...

Drive Out the Spawn of Satan.

But, with the roll pin out, I now need to be able to get the freakin' clutch lever off the shaft (the pedal cluster). I do not own a puller and my brass hammer has been ineffective in driving the shaft out the other way. Maybe the freakin' thing is not supposed to go out that way??

I am not clear on how a left handed bit would help with a roll pin???
