Best place for carbide bits... update with sort of finished 80% project on pg 2
RobertH:
for Black Friday, i'm going to be buying a jig and maybe an 80% lower or two. while i can buy a jig with carbide drill bits and an end mill, is there any place locally (Lincoln) that sells these bits:
3/8" drill bit
5/32" drill bit
19/64" drill bit
1/4 x 4" end mill (3 or 4 flute)
the tool kits online are roughly $45 for the carbide bits. online, the prices are about the same or even higher. i'd like to help out a local company if i can and see what i'm buying in person.
PS - i stopped by Harbor Freight, Menards and Home Depot and could not find those bits or end mill.

the hard part ive found is finding a 1/4 inch mill that long,

i found several options that are close on Amazon and eBay, but i'd rather not do business with anti-gun leanings.
i've been leaning towards the Modulus Arms universal jig and tool kit. hopefully Black Friday will be nice to me. i also wouldn't mind having a spare end mill too.
shooter:
there tool kit only shows one mill drill bit, you need a mill-drill bit, it can mill on the side and also drill a hole, but you need a 3/8 mill. and a 1/4 inch mill, you also need a mill with at least 1 1/2 inch of cutting surface, that one looks like a standard 5/8 inch cut length. also, the holes in the jig do not have hardened inserts in it,
if you want to, come on over and look at mine, that will give you a idea of the difference
also you do not drill the holes for the pins and saftey to size, you first drill the pin holes with a 9/64 drill bit, then you have to ream them to .156
the safety you use a 23/64 drill and ream that to.376.

Carbide and aluminum don't go well, high speed steel works best.
