    I cannot speak to the other options you are considering but I have one Kurt HDHM6C (cast iron jaws) on each side of Brother pallet machine. I run each vice with an air-over-oil cylinder and confirm...

    Hi Brent! Maybe 200 holes isn't too bad but the reason I thought it may be is because I recently ran the same material (not from the same batch, but the same "spec") and made 1,000 .323" holes about...

    Hi Ox,

    It looks like I was just asking too much from my HSS drill on this batch of material, since I did a couple bar changes with a new drill and had no problems (plus it is the same bar change...

    Neat charts, Matt! Thanks for sharing! It looks like they are all pretty similar in their recommendations. I am indeed cutting with oil, but what do you mean "1144 chips for no reason"??

    Hi guys,

    After loading a new bar it cuts off the first inch or so. I’ll have to look at the packing slip to see if it was real stress proof or just “1144.” I know the hardness was 24/25 HRC.

    It’s just regular CD. I think the ends are sheared. I still have the slug from the fresh cutoff I can measure to see if it’s round.

    I tried increasing the feed. See the attached pic for the various chips formed with their respective various feed rates. Do those look like proper 1144 chips to you? The little crumblies on the...

    Ha! Yeah, tomorrow I will do some math to see if the drills really ARE failing near the beginning of a new bar or if I am just making that up. It should be easy to add the amount faced and cutoff...

    Hi Rick!

    This whole debacle started with my assumption that I "should" be able to get several hundreds of 1.5X deep holes in 1144 with a plain old HSS drill but after trying several different...

    I know I was as high as 90% Z-axis thrust at .007ipr with the HSS drills and only like 55% at .006ipr with the split-point cobalt. I DID have to tighten up the main collet closer when I was at 90%...

    I suppose I never really know how deep to go on spotting! I think it's a 5/16" spot drill so it's not quite drilling a "hole", but I DID take that op out when I tried the split-point drill so I'm...

    Hi Rob! Yes - 753RPM and the fastest I fed the HSS was .007ipr and the one cobalt was .006ipr. I suppose I was just afraid of "pushing it" but maybe it's not forming a chip to take the heat away...

    I couldn't stop thinking about this so I snuck into work today and:

    1. Checked the QC records...this batch of 1144 is measuring 24HRC, which is normal.
