Stainless Drilling
(OP)
I am repairing the valve leakage on the gland packing,material valve is stainless steel. I have to make hole on the neck for injection sealing, so I have to drill the stainless steel material. The problem is stainless steel is very hard stuf. How do I drill stainless steel? what material for drill bit? and drill speed (I used air pneumatic drill, couldn't adjust the speed)?

Most pnuematic drills can be slowed in one of several ways:
1. Adjust integral flow control mounted on drill.
2. Or purchase a flow control and place it in line.
3. Or decrease air flow in line via air supply regulator at source.
4. Or, if all else fails, reduce volume of air supplied to drill by 'crimping' air supply line with hands or stepping on the hose.
This last option is not recommended - but it will work.
Also use lots of lube or cutting oil.

It is important to not let the bit spin on the SS material without cutting it. Once it's brandished it's too late.
Good Luck!
