Hammer Drill Bit Bosch Expert SDS plus-7X

The Bosch Expert SDS plus-7X Hammer Drill Bit set is made for SDS plus rotary hammers and contains 30 drill bits with a 10 mm diameter designed for heavy-duty concrete and masonry work. The bits incorporate a Full Carbide Head with a four-cutter geometry that resists jamming on rebar and reduces breakage during impact. This design targets long life and consistent drilling performance in reinforced concrete, helping professionals and experienced DIY users carry out fixation and installation tasks more efficiently.

Advantages

The Full Carbide Head with a 4-cutter layout provides improved resistance to wear and impact compared with standard two-cutter bits, reducing the risk of chipping or jamming on rebar. The bits are engineered to maintain drilling speed and accuracy in concrete and masonry and to offer longer service life, which lowers the need for frequent replacements. The SDS plus shank ensures secure tool engagement and quick bit changes in compatible rotary hammers.

Suitable for

• Drilling holes in concrete and reinforced concrete for anchors and fixings
• Masonry drilling in brick, block and stone
• Construction and installation work requiring repeated drilling
• Professional tradespeople and advanced DIY users using SDS plus rotary hammers

When it may not be suitable

This SDS plus-7X set is specifically designed for use with SDS plus rotary hammer drills; it is not suitable for standard drill chucks or rotary tools without an SDS plus adapter. The bits are optimized for concrete and masonry — they are not intended for regular use in metal, wood, or ceramic tile where different tip geometries and coatings are recommended.

Key specifications

• Type: SDS plus hammer drill bits
• Diameter: 10 mm
• Length: 200 mm working length with 265 mm overall length (per offer model)
• Quantity: 30 pieces per set
• Tip material: full carbide head with 4-cutter geometry
• Intended materials: concrete, reinforced concrete, masonry

How to use

Install the drill bit into an SDS plus rotary hammer by inserting the shank until it locks. Select hammer or hammer-drill mode as required and apply steady axial pressure while allowing the tool to do the cutting; avoid excessive lateral force. For deeper holes or frequent drilling, withdraw the bit periodically to remove dust and allow cooling. Use appropriate personal protective equipment including eye protection, hearing protection and dust extraction or a mask when drilling concrete.

What to consider before purchase

• Confirm compatibility with your rotary hammer: requires SDS plus chuck
• Verify that 10 mm diameter and supplied length suit your intended anchor or fixing sizes
• Consider whether quantity (30 bits) matches the scope and frequency of your projects
• Assess whether a different carbide tip geometry is preferable for non-masonry materials

Usage recommendations

For best results when drilling reinforced concrete, use the EXPERT SDS plus-7X in hammer mode, maintain steady feed pressure, and periodically clean the hole of debris. Replace bits showing significant chipping or loss of cutting performance to preserve hole quality and drilling efficiency.
