Handle Chipping Hammer

Jul 30, 2011

How come certain hammers cheaper ($5 range) than the others ($15-50 range)?

I am carrying out a work for my manufacturing engineering class and we are evaluating 2 different hammers.

1. We believe it’s steel casted hammer and it has a wood handle (we believe it’s whitened oak, but many of sites say hickory).

2. High carbon steel hammer, graphite handle

Questions – We can not appear to make use of our Rockwell tester to find the hardness for each one of the following surfaces – face, eye, and claw..does anybody know the toughest -> least toughest? I’d believe that the face area will be the toughest, however again, whether it’s way too hard, it could nick.

Wouldso would we all know whether it’s steel casted versus high carbon steel?

Just help! Any info could be great, even when I did not address it above! :-D

The face area of a high quality hammer ought to be the toughest. A top quality hammer ought to be drop forged (not cast) and also the face ought to be specifically treated to really make it extra hard so it doesn’t get broken striking nails frequently. This face treatment is more expensive to complete.

Oak is brittle and it has open pores. It’s a poor option for a wood handle. Hickory is flexible and strong and it is common for handles.

Wood handles could be sloppily fit rapidly, including utilizing a press to push the handle into place. Graphite and abs plastic handles need a mold to accept hammer mind and time for you to set. Time is profit manufacturing. Graphite is even more difficult but it takes baking, although that might be just carbon fibre.

In case your tester will not appraise the side or claw it needs work.
