Rasp Hardness 11 Oct 2011 17:40 #1

How hard is a Rasp and how it can be checked?

Anybody ever compared the hardness of various brands?

Will harder Rasps last longer on harder hoofs?

Thanks

It is difficult to find out much from the manufacturers, because they guard, as secrets, the composition of the steel and how it is heat treated. I'm guessing that rasps are made of high carbon steel with perhaps some chromium as an alloy for edge holding ability. Rasps and files are supposed to be quite hard, but I suspect they are tempered to a slight degree after quench hardening (about 300ºF?) to "take the snap out of them." If they were left fully hardened, they would be brittle.

I never did a comparison test.

Thanks Frank for the information.

Some of the rasps are through hardened as some members are resharpening these on a buffing wheel.

Which rasps are through hardened and which one are surface hardened?

Will appreciate the info.

Thanks.

A rasp is pretty thin, would prob be hard to only surface harden. Rasps in general are notoriously brittle. Put it in your vise and hit it with your hand, it will snap. Save Edge, and Hellers are what I'm most familiar with. The steel from rasps makes good tools though. I make a quick n dirty push gouge out of old rasp tangs, do a water quench at orange heat, suckers stay sharp!

As to brittle, I have. and have heard of other Farriers breaking a rasp by hitting a horse. I've explained to clients that this is why one needs to hit the horse with the edge of the rasp so as not to ruin a good tool, and that one can deliver a much greater amount of force using this method.
I've broken a rasp over my knee before but am hesitant yo try that with one of my Beast rasps.

I once went to a stable to shoe where the owners son was fresh out of shoeing school. There in the shoeing area were two halves of a nearly new Belotta (IMO one of the most brittle rasps). I looked at it and said "well Davey, have you learned hitting a horse with a rasp can be expensive". He agreed it was a good lesson.

The older I get, the more horses I shoe, the fewer things that I can absolutely, positively fix.

I noticed that with the Belottas too, Jack.

Interesting observations!

I broke one accidently by dropping on the garage floor.

As Frank Turley mentioned, tempering reduces brittleness, as well it will reduce the hardness also to some extent.

There must be a numerical value of rasp hardness. Anybody having info what it is?

What you are taking about is the Rockwell Test. The rockwell scale is used to measure hardness. You can get a set of files that will help you determin the hardness of metal.

so the tang of a rasp is usually softer than the rasp itself. Thats why you can bend the tang. So take a chainsaw file, or some sort of metal file and attempt to file the edge of the tang. The file should grab the metal. Now try it on the end of the rasp area, the file will glance off the metal. Thats how you know its been hardened.

Pet the horse, smack the owner. :D
