Drill hole size for 5mm LED fresnel lenses?

[Bret608]

Hi everyone,

Does anyone know what the proper drill hole size is for the 5mm LED lenses from Mouser? I'm going to have to order drilled enclosures from PPP until I have a drill press, and I'm guessing they'll need pretty specific measurements to accomodate special requests like this.

Thanks!

Are you talking about those vcc lenses?  I have some here, but my calipers are AWOL.  I do have a 1/4" hole drilled in an unused enclosure though, and I just dry-fitted one in there.  I think it might go if I pushed it, but it's awfully tight. I think 9/32 would be better?

Or get a $10 set of step bits from harbor freight and drill that one hole yourself with a handheld drill...

my trick for this is to drill a 1/4" hole and then slightly file/grind the edges of the hole with my dremel tool - one of the narrow grinding cones. I haven't found exactly the right size bit for this yet..

Ah- good to know that, strategy.  So would you say 9/32 is too big?

Thanks guys! I am definitely curious about the 9/32"--I do have a decent hand drill and a Harbor Freight close by, so I could go that route.
