Drill bit Bosch Expert SDS Max-8X 8 mm diameter, model 1765286, SDS‑max shank

The Bosch Expert SDS Max-8X 8 mm hammer drill bit is designed for use with SDS‑max rotary hammers to drill holes in concrete, masonry and natural stone. Its 8 mm diameter and SDS‑max shank ensure secure retention in compatible rotary hammers, delivering stable drilling performance for construction, renovation and heavy-duty repair tasks. The bit is engineered to withstand repeated impact loading and to maintain cutting efficiency on reinforced and unreinforced substrates.

Advantages

This SDS‑max bit provides reliable engagement with the tool’s chuck for reduced wobble and consistent hole geometry. The flute and cutting geometry are optimized to evacuate dust and debris efficiently, which helps maintain drilling speed and reduces heat build-up. Materials and heat treatment are selected to improve wear resistance under frequent hammer drilling, offering a balance between lifetime and cutting performance.

Подходит для

• Сверления отверстий в бетонных конструкциях
• Работ по кладке и кладочным швам
• Установки анкерных креплений и дюбелей
• Ремонтных и реконструкционных работ с использованием SDS‑max перфораторов

Key specifications

• Diameter: 8 mm
• Shank type: SDS‑max
• Intended materials: concrete, masonry, stone
• Tool compatibility: rotary hammers with SDS‑max chuck
• Primary use: hammer drilling (percussion drilling)

How to use

Insert the SDS‑max shank fully into the rotary hammer’s chuck until it locks. Select appropriate drilling speed and hammer function according to the rotary hammer manufacturer’s instructions and the material being drilled. Apply steady, moderate pressure without forcing the bit; allow the hammering action of the tool to do the cutting. Periodically withdraw the bit to clear accumulated dust and reduce heat. For deeper holes, withdraw the bit more often to maintain performance and prolong bit life.

Usage recommendations

Use appropriate personal protective equipment, including eye and ear protection and a dust mask or extraction system when drilling concrete or masonry. Match drill diameter to anchor or dowel requirements and avoid excessive lateral force. Store the bit in a dry place to prevent corrosion and inspect for wear or chipping before use; replace the bit if cutting edges are significantly worn.
