Drilling die cast aluminium - Garrard 301
Guys, need some advice. I would like to drill 3 small holes into the chassis of my Garrard 301. I intend mounting a tuned mass damper and stiffening the Garrard's chassis at the same time. I've been looking into drill bit. Would I be right in thinking that Cobalt drill bit's are the way forward, additional what's the best advice for drilling into the 301, is it best to take things slow and steady i.e. using the drill at a slow RPM?
Thanks
Andy
