Rotec hammer drill SDS-max Quattro-X Ø 22.0 x 200/320

The dimension specification says a lot about the use. The 22.0 mm is the diameter of the hole you drill, and for the length 200/320, 200 mm stands for the working length and 320 mm for the overall length of the drill bit. Therefore, look carefully at the depth you need and at what lies behind the hole, so the drill bit reaches far enough without you choosing an unnecessarily long one.

Which machines is an SDS-max Quattro-X hammer drill suitable for?

A hammer drill with an SDS-max shank fits a rotary hammer or combi hammer with the same SDS-max chuck. An SDS-plus drill does not fit in it, and vice versa. So first check which system your machine has. SDS-max is usually chosen for larger diameters and more intensive drilling, for example for pass-throughs, anchoring and installation work in concrete walls and floors.

Matching diameter and length to the job

The diameter you need depends on what you will place in the hole, such as an anchor, a feed-through or a pipe. For this, consult the specifications of the fastening material or the pipe feed-through. For the length, the working length must be at least equal to the desired drilling depth. If you are drilling through a thick wall or floor, also take into account the part of the drill bit that must protrude from the hole.

Use and maintenance of the hammer drill bit

Let the machine do the work and do not apply extra pressure, as this increases wear and the risk of jamming. Remove drilling dust from the hole regularly so that the drill bit keeps turning smoothly. Use eye, hearing and respiratory protection, as drilling in concrete generates a lot of noise and fine dust. After use, check the drill bit for visible wear or damage.

Frequently asked questions
