Why on earth would he need to use a SDS drill for drilling out bleed nipples?
He's already said he's using SDS drill bits and they aren't touching it, I didn't clarify whether I was suggesting an SDS drill or just using an SDS bit.
All SDS (Slotted Drive System) is referring to, is the manner in which the bit is attached to the chuck. How would this impact upon a drill bits ability to cut through a material? The only factor I can think of would be if the bit was slipping in a 'traditional' chuck.
Time to buy some sharp, decent drill bits

James hasn't gone into detail on whether or not it's the drill or the drill bit which is struggling. Of course he is going to need a decent drill bit, but also a more meaty drill may be needed.
