Hammers - All You Need to Know about the Different Types of Hammer and What They are Used For

Summary: There's an amazing variety of different types of hammers that are available! Which one you should use depends on the material that you're hitting and what you are hitting it for. We try to explain what all the different types of hammers are, why you would want to use them and in what circumstances a particular hammer should be used rather than another type of hammer. We will also give you a few hammer safety tips and pointers on how to use a hammer safely.

Safety Advice for when Using Hammers

You use a hammer to hit things and therefore hammer safety generally involves making sure that you cleanly hit the thing you intended, and that any fragments from where the strike is made are contained safely, or protected against.

In many cases you will need to protect the object that you are hitting with your hammer so that it is not damaged by the blow.

Here are our tips to make using your hammer safer:

  • Wear goggles; especially when you are driving in nails, breaking concrete or other materials that could shatter or fragment on impact.
  • Always use the head of the hammer, not the side to strike with. The metal is not hardened here, is much thinner where the handle passes through and can be damaged. The hammer is also unbalanced making it harder to make a clean strike and you will generally find it harder to see what you are striking too.
  • You hammer does need some maintenance. If the hammer handle is held in the head of the hammer with wedges these can work loose or the handle can shrink if it wooden. This means that the head can come loose and slip down the handle hurting your hands or even fly off. Tip: Soak the head of hammers with wooden handles to make the wood expand which will secure the head to the handle again. You might need to add new wedges if required.
  • The face can become polished with use and can slip off nails when struck; roughen the face with some abrasive paper to prevent this happening.
  • Protect delicate work from hammer blow marks by using a piece of scrap wood to adsorb the blow. Place the off-cut onto the surface you wish to hit and then strike this rather than the object directly; it will protect it.
  • To protect delicate wood work, use a punch to sink the nails without striking the wood itself. You can see our range of punches here.
  • Always use the right hammer for the job you are undertaking; It makes the task easier and will help to avoid possible damage to the hammer, yourself and the project that you are working on.

The Parts of the Hammer Explained

Although a hammer is essential a very simple tool, there is some terminology that has developed to describe the various parts.

Parts of a Hammer

The basic shape and design of a hammer has not change for hundreds of years. Traditionally the handle was made from wood, most commonly ash or hickory. Now this is changing with the introduction of other materials which can absorb the shock from the hammer blow better or are considerably lighter and/or stronger.

In most cases the head of the hammers is made of metal and this is the part of the hammer that shows the greatest variation. Here are some of the common parts of hammer heads:

Generally the handle is attached to the head through a hole in the head (the eye). The handle is secured by driving wedges into the wood of the handle to make it expand and fit the hole tightly. This allows the handle to be changed should it become damaged.

Types of Hammer and What they are Used For

There is a considerable range of hammers that can be bought, and the average person will only have 2 or 3 in their tool bag, and this is probably all that they will ever need. You will be able to see and purchase a wide range of hammers that have been organised into groups based on what they do on this page of our shop.

These are the most common types of hammer that people use today, both for DIY and in the trade:

Claw Hammer

Claw Hammers are the most common type of hammer and probably the one that comes to mind when most people think about a hammer. They are very versatile and can be used for a great many jobs so are an absolute must for any tool bag. The most common weights are from 16 to 24 ounces (455-680g).

Claw hammer

The claw is used as a lever; it generally has a notch which is used to lever out nails from timber. The claw is inserted under the head of the nail so that it catches - this can take a little jiggling about. The nail is then levered out by pulling back on the handle and using the curve of the claw as the fulcrum. The claw can be used to lever other things, such as floorboards, but excessive use can put strain on the join between the head and handle, so check this regularly.

Cross and Straight Pein, Warrington or Joiners Hammers

4 oz Cross Pein Pin Hammer

4 oz Cross Pein Pin Hammer - Available from our store

These are different hammers with a variety of uses which are determined largely by the weight and strength of the head. They all have a similar shaped head with a cross or straight pein (also spelled "Peen") on the opposite side of the head to the Bell (or Poll).

Warrington, Joiners and Cross Pein Pin Hammers are all mainly used for wood working. The cross pein is used to start off the tack or nail. If you hold a small nail or tack in you fingers it can be difficult to hit the head of the nail without hitting your fingers.

The cross pein allows you to gentle tap the nail between your fingers without striking a finger or thumb. The pein can be at right angles to the handle (straight pein) or parallel to it (cross pein), but most commonly you will see the cross pein as this is most useful for starting off tacks and small nails.

The heavier cross or straight pein hammers are mostly used for shaping metal.

Ball Pein

These hammers are sometimes called engineers or mechanics hammers. They have a rounded, hence ″ball″, pein which is used for shaping metal, closing rivets and rounding edges off metal pins and fasteners.

Peening, a metal fabrication process, is little used these days, and involved hardening a metal surface with repeated impact. This was mostly done by the flat face of the hammer, in fact.

16 oz Ball Pein Hammer

Ball pein hammers range from 4 oz - 2 lb. (55 - 1100g), although the majority are in the region of 8 - 12oz (110 - 165g). The handles are traditionally wood, usually Ash or Hickory, although modern materials are now used as they suppress the vibration well.

Club or Lump Hammer

This is used for hitting cold chisels to break masonry or simply to bash things up like a tiny sledge hammer.

3 lb Club hammer

3 lb Club hammer - Available from our store

They are usually double faced and have a wood or resin handle. 2-3 lb is the typical weight, although they can weight as much as 4 1/2 lbs. These are a vital tool for a builder and will be used throughout a building site.

Sledge Hammer

3 lb Sledge Hammer

3 lb Sledge Hammer - Available from our store

These are similar hammers to a club hammer, except they have a longer handle and tend to be a little heavier (3-14 lbs).

They are used for breaking up masonry, stones and concrete. They are also useful for driving in stakes. Real force can be delivered by swinging the hammer like an axe; the longer handle will provide huge momentum and hitting power when combined with the weight of the head.

A variation is a Deadblow Hammer. This is another hammer for minimising damage to the surface while designed to deliver the maximum power on impact. They generally work by having an internal cavity filled with steel or lead shot. This evens out the power of the impact in the blow, enabling a more powerful blow to be delivered without risk of damaging the target as reduces rebound when strike is made; the head of the hammer stays on the surface begin hit.

Remember your hammer safety!

Mallet

A mallet is a wooden block on a handle. It is used to hit and drive a chisel, knock in dowels or to tap wooden joints together. This is an essential tool for a joiner or carpenter.

Carpenters Mallet

They are typically made of beech (a hardwood) and are used where a metal hammer might do damage to the piece or project being worked on or the other tools, such as the chisel.

Generally the head will be slightly tapered to ensure correct contact with the piece being worked on.

Even More different Types of Hammers

So far we have covered the most commonly used type of hammers, but there are a range of less frequently used hammers and hammers that are used for specialist jobs. Here is a selection:

Aluminum Hammers - These are soft faced hammers that are used for molding metal without damaging the surface being molded.

Drywall Hammers - A dry wall hammer will have a small axe on one end of the head and a hammer face on other. Axe is used for cutting plasterboard for pipes and making other holes or opening in the plasterboard. Sometimes they have a magnetic head for finding studs with screws/nails in, which can be very useful. Traditionally a lath hammer would have been used but now plasterboard is used there is no need to a lath hammer except in older buildings.
