I'm working on replacing the front site on my S&W M325. I bought some numbered drill bits to drill the hole for the pin, but the sight is harder than I expected. I've gone through 6 bits and only got about half way through.
Does anyone know of a source for quality drill bits size #51?

I'm pretty sure I got mine from Brownells

Thanks, but I was kind of hoping I could find something local.

That carbide bit at Home Depot may be the best option.

Might want to check your local Fastenal or Grainger.

I have the bits from Menards, they're junk.
I ordered the cobalt bits from Home Depot, of course they're not in stock. We'll see how good they are.
If they don't work, I guess it's off to Granger.

If the Cobalt don't work (they should) you might talk to OldmanFCSA and pick his brain for an idea. When drilling with the cobalt, be sure to use a coolant, it will help prevent the bit from dulling as quickly.

I see that McMaster-Carr has solid carbide; and TiN and TiAIN coated bits.
https://www.mcmaster.com/solid-carbide-drill-bits/carbide-drill-bits-11/Otherwise, I might be inclined to look around for a machine shop in the area, stop in and ask for suggestions and buy a bit off them if they are willing.

The menards comment is an understatement.

You could hear up the part to take the temper out. Just saying
