Dull, low-grade drill bits stall in concrete, overheat, and leave ragged holes that slow your project down. Whether you're anchoring bolts into a foundation, running conduit through a block wall, or mounting fixtures in reinforced concrete, the bit you use determines how fast and cleanly the job gets done. This 9-piece SDS-plus set is built for hammer drills and designed to cut through masonry without seizing or excessive vibration.
The set includes 9 bits ranging from 5mm to 16mm (5, 6, 6, 8, 8, 10, 12, 14, 16mm), each 160mm in total length with a 90mm maximum cutting depth. Bits are manufactured from premium steel with a reinforced core and feature a full carbide 4-cutter tip with centering point for precise hole starts. The 45° outer tip angle and grooved carbide plate with notches penetrate material efficiently and resist seizing under load.
Use this set for drilling anchor holes in concrete walls and floors, installing fasteners in block and brick, running electrical conduit through masonry, and general construction and renovation work requiring a hammer drill. The vortex flute design clears dust continuously during drilling, keeping the cutting edge clear and reducing heat buildup on extended runs.
Drill anchor holes in concrete slabs, block walls, and reinforced foundations for structural fasteners, rebar ties, and embedded hardware.
Run conduit, pipe sleeves, and cable through masonry walls and concrete floors — the 9-size range covers standard knockout and sleeve diameters.
Mount shelving, TV brackets, handrails, and fixtures to concrete or brick walls with confidence — the centering tip prevents bit walk on hard surfaces.

These bits require an SDS-plus hammer drill or rotary hammer. They use the SDS-plus locking shank system and are not compatible with standard keyless chuck drills.
These bits are designed to resist reinforced concrete. However, if you hit rebar directly, stop and reposition — carbide tips are not rated for cutting hardened steel rebar.
The maximum cutting depth is 90mm. Total bit length is 160mm, with the remaining length used for the SDS-plus shank engagement.
Yes. These bits are suitable for concrete, brick, block, and general masonry. They are not intended for wood, metal, or ceramic tile.
The duplicate sizes (6mm and 8mm) are the most commonly used anchor hole sizes. Including two of each reduces downtime when one bit dulls mid-project on a large job.
Use hammer drill mode (not rotation-only), apply steady pressure without forcing, and allow the vortex flute to clear dust naturally. Avoid overheating by pausing on deep holes. Store bits in a dry location to prevent corrosion.
Always wear ANSI-rated safety glasses and an N95 dust mask — concrete dust contains silica and is a respiratory hazard. Use hearing protection during extended drilling. Ensure the workpiece is secure and check for embedded utilities before drilling into walls or floors.
