Ewan is right in some cases the drill is softer with the coating and will just burn out once the coating has worn. SS 500-800rpm maybe, its alot about feel so its hard to advise on speeds. Top tip make sure the drill is sharp otherwise SS will destroy it.
Geoff, you get used to it.
Carnt remeber the last time You came around to my house and i havnt said Ed, youve got swarf in ur eye again
well actually it did start to smoke and go black, the reason why im asking for advice
Slow the speed down, use lubricant. Sharpen your drill bit.
If you are going for a lot of drilling I cant recommend enough a set of cobalt steel drill bits (you can pick up a set for around £20 on ebay). Fantastic for drilling anything!
Getting a new set for valentines day. She really does know how to spoil me
HAHAHA gary i looked at your post neat top about holding your material as a time saver i remember when i did that nearly lost my fingers, the drill bit grabbed and it pulled my hand slamming it against the vice with my fingers between the bit of plate i was drilling and the vice lucky for me the drill wasnt in the chuck very tight so the bit just spun in the chuck, left me with sum nasty cuts but i would have lost my fingers for sure if i had tightened the drill bit properly.
A god tip is to use hard metall (tungsten) drill IF you can get our hands of it, BUT it need to be steady if you drill whit this or it will brake,its good for hardenad steel, rpm; 2000.
