This drill bit is designed for anyone who frequently drills into solid materials: DIYers, installers and professional builders. It solves the problem of slow progress and sticking out during long, strenuous drilling jobs. The large 22 mm diameter and long 600 mm working length allow you to drill deeper and wider holes without compromising on accuracy or speed.

The core of the product is the innovative carbide head geometry with multi-cutting edge construction and advanced X-Grade Carbide technology, which ensures high resistance to breakage and an exceptionally long service life. The SDS-max chuck ensures maximum power transfer from the hammer to the drill bit, which significantly reduces vibrations and improves drilling speed, even in the hardest materials. The special Hitachi–Bosch spiral design optimally evacuates dust and prevents jamming – which means smoother and cleaner drilling in all conditions.

In addition, the product does not need to be changed or sharpened frequently, which allows for uninterrupted work and fewer interruptions on the construction site or in the workshop. The ergonomic design and high-quality Bosch materials make the user experience pleasant even when using the tool for long periods of time – reliable, fast and safe, for ambitious home projects as well as the most demanding professional tasks.

Same summary

The Bosch EXPERT SDS-max-8X hammer drill bit, with a diameter of 22 mm and a working length of 600 mm, is adapted to more demanding drilling tasks in concrete or stone. Due to its robust design and length, it is suitable for users who need precise and deep holes in harder materials, e.g. in adaptations, installations or major construction works. The drill bit is less suitable for occasional home use or drilling in softer materials, where specialized performance is not necessary. It is important to check the compatibility of the tool with the SDS-max chuck and avoid using the drill bit on unsuitable materials or with unsuitable tools.
