Dead blow hammers

[John-MI]

What are dead blow hammers used for. They seem to hit harder than a steel one.

Hello john-mi,

A hammer with an attitude! Comes in handy on surfaces that may be chipped, other wise........ it is just a hammer HA!HA!

The quick answer is that dead blow hammers transfer a greater portion of their energy to the workpiece instead of it being used to lift the hammer back in the air in the form of a rebound. They also are useful in places where a rebound might hit valuable parts close to the strike area--working on vehicle brakes, with the lines, fender wells, and such close by, is one such application, though there's thousands of others.

Dead blow hammers are designed to drive items without deforming the item being driven. An example would be driving an interference fit coupling onto a shaft without "mushrooming" any steel components.

We used them for installing bearings.

I think you are confusing a deadblow hammer with a soft-faced hammer, such as a brass or plastic nor rubber faced hammer.

NOT marring up the workpiece and hitting with firmly with "deadblows" are two different things, IMHO.

A dead Blow hammer doesn't bounce. It is a "DEAD BLOW". A good example is setting gang nails when building trusses.

Mine shattered with the first blow, when temp -0 F. Learned a quick lesson.

It's just a super hammer. It hits harder than the same weight regular hammer and doesn't bounce as much. I have several and use them all the time.

John MI,

Dead-blow hammer is nothing special to my thumbnail...blackens it just as quick!D.

I use dead blow hammers to assemble plastic injection molds. They work well without leaving marks in the steel or mushroom pins. No way will they hit harder than a steel hammer the same weight. When push come to shove I use the steel.

Dad always told me "any idiot can pound with a hammer, it takes skill to know how hard to hit"!!!

A dead blow hammer has an amount of weight that is allowed to move inside the head. As you start swing the hammer, inertia causes the loose weight to stay on the end opposite that will strike the object you are going to hit. When the hammer head makes contact with the struck object it will bounce back. The internal weight hits that end of the head about the time the rebound starts and counteracts the rebound affect.

Two laborers breaking up floor tile one about 70 the other 25 . The young guy is slamming his sledge smashing single tiles ,the old guy is gingerly coming down at a certain angle and taking out four tiles at a time. So skill is involved with hammers too. LOL

Not correct. a rebounding hammer transfer more kinetic energy to the object being hit. The rebound is in the opposite direction from the initial swing. That kinetic energy in the rebound is generated by an equal transfer of energy to the struck object. So, the struck object receives the kinetic energy of the initial swing plus the kinetic energy of the rebound motion.

Golly Gee! I've been using plain old hammers for over 70 years; guess I'll keep using regular hammers.

 

[Jason the Red]

No I know exactly what I'm speaking of. I own brass hammers, brass drift pins, and mallets as well. You should probably Google dead blow hammers.

Aw, I'm gonna pass on the GOOGLE thing 'cuz it seems I have the same assortment of hammers as you do!
