SDS plus-7X drill bit set Bosch 12x100mm (165mm overall) — 10 pieces

Set of 10 Bosch SDS plus-7X drill bits with a 12 mm working diameter, 100 mm flute length and 165 mm overall length. Designed for SDS-plus rotary hammers, this set is intended for efficient drilling in concrete and masonry. The bits are supplied as a 10-piece set to support repetitive drilling tasks and offer uniform hole dimensions for anchoring, fastening and through-holes in structural materials.

Advantages

These SDS plus-7X drill bits combine a robust carbide tip geometry with a reinforced flute design to improve drilling speed and maintain accuracy during continuous use. The standardized SDS-plus shank provides secure tool engagement and quick bit changes, while the 165 mm overall length gives access to deeper drill positions without compromising stability. The 10-piece packaging ensures consistent replacement availability on job sites or in workshops.

Suitable for

• Drilling holes in concrete for anchors and dowels
• Fixing mechanical and electrical installations in masonry
• Installing anchor bolts and threaded rods
• General construction and renovation tasks requiring multiple identical holes

Key specifications

How to use

Fit the SDS-plus shank into the rotary hammer’s chuck until it locks. Select the rotary hammer’s hammer-drill mode appropriate for concrete or masonry. Start drilling at low speed to position the bit, then increase to the recommended operating speed and pressure for the machine and material. Periodically clear dust from the hole and withdraw the bit occasionally to remove debris and maintain bore efficiency. Replace worn or damaged bits to maintain hole quality and safe operation.

Usage recommendations

Use with compatible SDS-plus rotary hammers and appropriate personal protective equipment (safety glasses, ear protection, dust mask). For best results in reinforced concrete, inspect the bit for wear after encountering rebar and replace if the carbide tip is chipped. Store the set in a dry place and keep individual bits organized to avoid damage to cutting edges.
