Lately we've been doing alot of anvils out of 3/8 or 1/2" Hardox steel (Rc 45-50)
Aside from having to machine profiles and pockets we also have to drill some mounting holes.
The obvious solution is to use carbide drill.
The drill we purchased fot this job is the cheapest uncoated micrograin carbide drill we coud buy.
Basically the hole specs are:
Here is what i came up with.
Speed: 600 RPM
Feed: 0.5 IPM
Coolant: Air blast + Oil
Seems to be working fine.
One drill lasts for around 40 holes.
