Broca de martelo Bosch Expert SDS-max-8X, 16 mm de diâmetro, 200 mm de comprimento útil

Bosch Expert SDS-max-8X hammer drill bit with a 16 mm diameter and 200 mm working length is a rotary‑percussion drilling tool engineered for use in SDS‑max holders. Designed for drilling into concrete, masonry and similar mineral substrates, this drill bit offers the reach and stability required for medium‑depth anchor, dowel and rebar installation. The geometry of the cutting head and shank system provides efficient material removal and secure retention in SDS‑max chucks, making it suitable for professional construction and renovation tasks.

Advantages

The Bosch Expert SDS-max-8X drill bit combines precise diameter control and a consistent 200 mm working length to deliver stable drilling performance in dense substrates. Its SDS‑max shank ensures firm engagement with compatible rotary hammers, reducing bit wobble and improving power transfer. The cutting profile optimizes dust evacuation and reduces clogging during rotary‑percussion operation, which helps maintain drilling speed and prolongs service life under typical jobsite conditions.

Suitable for

• Drilling holes for medium‑depth anchors and dowels in concrete
• Creating guide holes for reinforcement and rebar positioning
• Rough drilling in masonry, blockwork and similar mineral materials
• Renovation and repair work where controlled 200 mm reach is required

Key specifications

• Diameter: 16 mm
• Working length: 200 mm
• Shank type: SDS‑max compatible
• Intended material: concrete and masonry
• Tool type: rotary‑percussion (hammer drilling)

How to use

Select a rotary hammer with an SDS‑max chuck and install the 16 mm bit by inserting the shank until it locks in place. Mark the drilling position and, where possible, use a center punch or guide to prevent walking. Start drilling at low speed to establish the hole, then apply steady pressure with the hammer function engaged for concrete or masonry. Periodically withdraw the bit to clear dust and debris and to prevent excessive heating. For anchor installation, confirm hole depth matches anchor specifications before cleaning and inserting the fixing.

Recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and dust extraction or a dust mask. Ensure the rotary hammer is set to the correct mode for hammer drilling and avoid excessive lateral force to preserve the bit geometry. For prolonged drilling in reinforced concrete, cool the bit by intermittent withdrawal and clearing to extend service life. Store the bit in a dry place and inspect for wear before use; replace if the cutting edges or shank show significant damage.
