diamond tipped bits

[jeepers]

How does everyone keep their diamond tipped drill bits from wearing down quickly?

I have tried the pointy one, the round tipped one, but both were really small

they didn't last more than 5 uses however

does using running water work?

Running water greatly helps, as does going slow - it'll take longer, but the bits run cooler and last longer... The local hardware store should have everything you need to connect a length of 1/8" flexible hose to a garden hose with a valve, so you can stick it where you're working for a small controlled flow. Much easier than trying to use the garden hose itself.
