Sledge hammers are sold by head weight, and the weight you need is set by what you are hitting and how long you have to swing. A 4 kg head on a 900 mm handle delivers more usable force than a 10 kg head on a short handle used by someone who cannot control it.
| Type | Head weight | Handle length | Typical work |
|---|---|---|---|
| Light sledge | 4 kg | 600 - 800 mm | Stake driving, light demolition, fencing |
| Medium sledge | 6 kg | 700 - 900 mm | Breaking concrete, formwork, general site work |
| Heavy sledge | 8 kg | 800 - 900 mm | Demolition, quarry and railway work |
| Extra heavy sledge | 10 kg | 900 mm | Breaking rock, heavy demolition |
Standard production range. Head weights outside this range are made to order at MOQ 500 pcs.
4 kg is the portable option: fencing, stakes, light demolition, and the weight most often bought for general site use. 6 kg is the compromise for breaking concrete and formwork where a 4 kg head needs too many blows.
8 kg and 10 kg are production tools: quarry, railway, heavy demolition. They are not bought for occasional use, because the risk of injury rises faster than the productivity gain.
Force comes from head mass times swing speed. A 900 mm handle lets a 4 kg head reach speed a 600 mm handle cannot, which is why a longer handle often outperforms a heavier head. It is also why the handle should match the user's height.
Check the wedge and the eye before every shift; a loose head is the most common failure. Wear eye protection, and never strike two sledge hammers together — the faces can chip. For railway and quarry work, specify the head hardness and the handle grade at order time.
4 kg, 6 kg, 8 kg and 10 kg cover most trade use. 4 kg is the most common export size; 10 kg is for heavy demolition and quarry work.
No. Force depends on head mass and swing speed. A 4 kg head on a 900 mm handle often delivers more usable force than a 10 kg head the user cannot swing properly.
600 to 900 mm depending on weight. Heavier heads need longer handles so the arc does the work rather than the arms.
A club hammer is a short-handled one-hand tool, usually 1 to 2 kg. A sledge hammer is a two-hand tool starting at 4 kg.
Yes, hickory, fibreglass and steel handles are available across the range.
