Hammer drills: why do they need specific attachments?
The same goes for a hammer drill. These power tools are designed to take all kinds of drills, bits and chisels to tackle different drilling and punching tasks.
With an SDS chuck, either SDS+ or SDS Max type, the drill bits and chisels have a hollow base for more rapid attachment. So you can switch from demolition to drilling with a single click!
How to choose your drill bits?
Some hammer drills offer several different settings, including a simple rotation mode. This allows you to work without percussion, just like a standard drill; very useful for drilling wood!
Hammer drills: how to choose your concrete bits?
A wide range of bit diameters are available (from 5mm to over 52mm), at varying lengths - from 10cm up to a stonking 1m!
Drill bits vary, but are often modelled after the high-quality drill manufacturers. They can have two to five cutting edges - three or more are advisable for good penetration into most masonry.
Hammer drills: how to choose your demolition chisels?
Unlike drill bits (only used for drilling), demolition attachments can be divided into several families:
- Flat chisels: consisting of a shank and a flat head, these are used to break through unreinforced concrete and other less robust building materials. Flat chisels are also useful for making breaches, separating stones or bricks, and cleaning up formwork. You can get chisels of varying lengths (25cm is quite versatile) and different head widths (from 20mm to over 100mm). The larger the chisel head, the softer the material it's used on. For example, a 20-25mm chisel is perfect for breaking concrete, while a 75mm model will do the trick on ceramic and tiles.
- Pointed chisels: this pointed masonry attachment can tackle harder materials. Here, it's length and diameter that are decisive. It's worth investing in a range of diameters from 14 to 18mm as this will cover most small demolition work. As regards materials, tungsten carbide tips are once again a very good option for their extended lifespan and limited wear.
Pyramidal point chisels: very similar to the above, except with (guess what) pyramidal rather than conical points. The same selection advice applies to this type of chisel attachment.
