The gent I bought my replacement loader cutting edge from wanted to dump the rest he had. Had intended to make a press frame from them then realized they were a bit too hard to drill.

He has sold me four additional edges, they are 8 feet long 10 inches wide a full 1 inch thick and beveled the last 1 1/2 inch.

PM me if interested.

A bit to hard? I think it would take a diamond bit to drill them. They're the hardest stuff I've ever tried to work with. I also wonder if it wouldn't be a good idea to preheat any area you are going to weld to keep it from surface cracking?

Leon got me started think of my neighbor that had to learn most things by experience. Was building a lite quick brush rake on his dozer to clean up his walnut orchard after pruning.


Had some 3/4 x 3 springs out of a junk TD18 dozer. Had a frame of pipe and started welding the spring steel on every so far. They were popping and cracking as he used a general purpose welding rod. He got done tacking the last one as the first fell on the dirt. They all feel off.

Would think the hardened steel would not be the best to us as a frame for much of anything.

Wonder if you could heat it enough to soften the steel?

Do you know what kind of steel it is? AR400 and AR500 series are supposed to be drilled with HSS at low speed with coolant I think a bolt on replaceable cutting edge would be preferred.

I wonder if drilling is impossible or just difficult. Did you try carbide?

The blades I was working with were off of motor grader. They may have been harder than what you're talking about. I know when they broke they just went "tink" and that was it. I have had good success preheating hard material and welding it. Not red hot now. John some metals will soften when heated red hot, but there are others that will air harden and I don't remember the alloy that makes it do it.

Being cutting edge will probably be high chromium content so will not so much anneal. Are harder than the hubs of He-- and about as heavy! I have not put a drill to them but have seen these drilled as noted low speed in a drill press or mill with LOTS of coolant applied.

Still I have bought them, pick them up on Tuesday morning and will have them as he did sitting collecting dust for awhile.

As received. MODOT sale was where they came from, for Case Wheeled loaders they had ceased to have.

dont know about drilling, but when i re did the cutting edges on my dozer i used pieces cut from a cat loader cutting edge. i preheated with a torch, not cherry just hot, and welded with 7018 rods.  these were on the end of the blade and have taken full force of the dozer and still holding.
