In need of some new chisels

[luke1984]

Hi foggers just after some input. Had my chisels reground by a company and they must have messed the tempering up. They are so brittle when I cut ash to day the end of the chisels chip and broke away. Haven't got loads to spend but your in put would help.

Depends what you do with them and budget. But for general carpentry duty, Irwin Marples Splitproof with the yellow and red resin handles are a good timeproven set.

No comeback on the idiots that ruined your existing set?

 

[luke1984]

No they have Said it nothing they have done. Full of S#*T ! They are marples yellow and red. Had them for 16 year I'm so angry with them [mad]. Got around £100 -  140 to spend at the moment. Been looking at narex. They will be used for all aspects. Sorry I never put this in the start.

Did they make them too brittle with too much heat during sharpening?

I would also suggest sorting out a sharpening method, and save some funds for that.

 

[luke1984]

Yes from what I read about on the web. I've got water stones and diamond stones but I had a week when I was not useing them so I'd have them reground. Won't do that again.

they will chip unless you put a secondary bevel on them

Sorry to hear of your misfortune.  It is a shame there are those with no sense of pride in what they do.  I have a full set of Narex, and love them.  Fairly easy to sharpen; most already had dead flat backs.  For basic work with hardwoods, stay sharp for long time.  And the best part, when I got mine from Lee Valley, they were the least expensive chisels in the catalog.

Best wishes, Don

Can't see any reason for you not to go with Marples again in you target price bracket.

 

[luke1984]

All ways put a secondly bevel on and still chipped out. I wasn't sure if the new marples are as good as my old one were as their so cheap now. I always try to buy the best I can afford. (I thank you all for you input keep it coming).

Does any body know if I can sharpen the brittle part of the steel out( wet grid a 1/4 inch off them ) in the future?

Probably, but it will take a long time.
Sounds like they ruined them by overheating them. Those marples chisels chip but you really have to work at it. Buy new ones and don't send your chisels out to be sharpened anymore.

If I was you I'd share the name of the mob that damaged your chisels ... possibly save other Foggers similar grief [sad]

On fixing them, Tim's right ... the effort could be massive.

Once you get past the first 1/8" of an inch they should be fine.

Use a water cooled machine like a Tormek and you're good to go.

I had a similar problem with chisels and after a while they act normal.

Good luck now.

I have two sets of the Narex, one set of bench chisels and one set of mortising chisels, and like them very much.  They seem to be holding up well after a couple of years, and are good value for the money.  I'm retired and build furniture  as a hobby.  I don't know how they would hold up if used professionally on a daily basis.

^yep^ - you would have to get it hot, and there is so little material at the end that it gets hot.
further back is more of a heat sink.

I doubt you would need to go past a mm... But that is a lot of material to remove.

Overheating chisels during grounding would get them annealed. Making them brittle requires quenching right away. Am I missing something?

 

[Bohdan]

If they simply overheated chisels during grounding they'd get annealed. Unless they quenched them right away. I'm I missing something?

Because the sharp edge is so thin it gets hot very easily and it also cools very quickly, this it what over hardens it making it brittle. The effect is reduced as the material thickens so it may only be the extreme tip that is affected.

Makes sense. Easily fixed then.

Investing in a Tormek is a significant ask for a fella that had his Marples sharpened by another party!

It's also likely that the work required on the different width chisels could very .. making them a mix in reliability.

I like my MHG chisels. Seem to be decent quality for the price.
