Flat bottom drills

[Programinator]

Hi,

Sometimes I need a simple hss flat bottom drill for making deep counterbores.  I usually have a local grinder guy make them for me.  Does anyone know of a manufacturer of these that stock them so I can just order them?  THanks

Not HSS but these are our normal goto for flat bottom drill needs.

Yg sells flat bottomed drills too.  I haven't tried them.

I've used then a couple of times. They work well.
They are too short for many jobs, but they work if they have the reach you need

NACHi makes a great selection.
Multiple lengths, with or without corner radius, and also coolant thru.

Thanks guys.  We do lots of job shop parts.  No real production stuff.  I don't really need carbide.  Was looking for a cheap solution.  Thanks

We just grind them either by hand and or with a surface grinder (relieve them by hand). We are and R&D facility so HSS is it most of the time.
