Broca de martelo Bosch Expert SDS plus‑7X, diâmetro 14 mm, comprimento 400/465 mm

Bosch Expert SDS plus‑7X hammer drill bit, diameter 14 mm, length 400/465 mm, is a single SDS plus accessory for rotary hammers designed for drilling in concrete and masonry in hammer mode. The bit features a full carbide, four‑cutter head intended to resist jamming on rebar and to extend service life when used for fixing, anchor holes and rebar clearance in reinforced concrete. The shank is compatible with SDS plus systems for use in professional and DIY rotary hammer drills.

Advantages

The full carbide 4‑cutter head provides improved impact resistance and reduced risk of jamming compared with two‑cutter designs, supporting longer drilling life in concrete and reinforced concrete. The SDS plus shank design enables secure, efficient transfer of hammering energy from compatible rotary hammers. The 14 mm diameter and extended working length allow deeper anchor and fixing holes while maintaining stability during hammer drilling.

Suitable for

• Drilling holes in concrete and masonry for anchors and fixings
• Drilling through reinforced concrete where clearance of rebar is required
• Professional construction tasks and advanced DIY projects using SDS plus rotary hammers

How to use

Insert the SDS plus shank into the rotary hammer chuck until it locks according to the tool manufacturer’s instructions. Select hammer drilling mode and use steady, moderate pressure; allow the drill bit to do the cutting while maintaining alignment with the intended hole axis. Withdraw occasionally to clear dust from the hole when drilling deep; keep the working length and overall length in mind to avoid exceeding the usable drilling depth. Use appropriate drill speed and hammer settings recommended for concrete on your rotary hammer.

Recommendations

Wear suitable personal protective equipment, including eye and hearing protection and dust mask. Use water extraction or a dust removal system when required by regulation. Do not use the bit in rotary‑only mode without hammer action for best performance in concrete; match the drill bit diameter to recommended anchor or fixing sizes.
