Bosch SDS max-7 vrták pre vŕtacie kladivo 1,8 cm priemer 1340 mm dĺžka

The Bosch SDS max-7 Drill Bits Rotary Hammer 1.8 cm Diameter 1340 mm Length are designed for high-speed drilling with rotary hammers that accept SDS max holders. The solid carbide S-cutter and inclined side cutters enable very fast penetration into concrete, reinforced concrete, limestone and masonry. The bit's vibration-optimised flute design improves power transfer and increases drilling speed while a wear mark gives a visual indication when the diameter is approaching tolerance limits for metal anchor setting. The product carries the PGM Masonry Drill Bit Association Board test mark, confirming tight tolerances, precise hole dimensions and secure fixing performance.

Advantages

The SDS max-7 geometry combines a solid carbide S-cutter with inclined side cutters to deliver fast drilling and reliable cutting performance. The vibration-optimised flute reduces energy loss and helps maintain drilling speed under load. A visible wear mark provides an easy check for remaining usable diameter, and the compliance mark from the masonry drill association assures consistent manufacturing tolerances and dependable fixation strength.

How to use

Install the drill bit in a rotary hammer with an SDS max holder according to the tool manufacturer's instructions. Select an appropriate drilling speed for the material and apply steady pressure without forcing the bit; allow the tool's hammering action and the S-cutter geometry to remove material efficiently. Monitor the wear mark to determine when the bit diameter is near the tolerance limit for anchor installation. Periodically withdraw the bit to clear debris from the hole and to prevent overheating. Use appropriate personal protective equipment, including eye protection, hearing protection and dust control measures when drilling.

Recommendations

For best results, use the SDS max-7 bit with a rotary hammer matched to the bit length and intended application, keep the bit straight while drilling to maintain tolerance, and replace the bit when the wear mark indicates the hole diameter no longer meets anchoring requirements. Routine clearing of debris and use of dust extraction prolong bit life and maintain drilling efficiency.
