SDS Plus & SDS Max Carbide-Tipped Hammer Drill Bits
DISLAB Precision Professional-Grade Concrete & Masonry Drilling
Our SDS Plus and SDS Max carbide-tipped hammer drill bits are professional-grade cutting tools designed for impact drilling in concrete, masonry, stone, and reinforced materials. Manufactured with a high-speed steel body and premium YG8 tungsten carbide cutting tips, these bits combine extreme hardness with durability to withstand high-impact forces of rotary hammer tools. Available in both square (four-groove) and round (two-groove) shank configurations, they are compatible with a wide range of light and heavy-duty electric hammers. With a variety of diameters (M6 to M32) and working lengths (110mm to 500mm), they provide fast, clean, and precise hole drilling for anchor installation, plumbing, electrical, and general construction applications.
✔ Ideal for professional tradesmen & DIY | OEM/ODM custom lengths available
Key Specifications
Available in multiple diameter & length configurations: Our comprehensive range covers 6mm up to 32mm diameter, with working lengths from 110mm up to 500mm. The SDS Plus shank (round 2-groove) is suitable for light to medium-duty hammers, while the SDS Max shank (square 4-groove) delivers maximum impact energy for heavy demolition and deep hole drilling. Custom diameters and special lengths are available via our OEM/ODM service.

Product Advantages
Precision-ground YG8 Tungsten Carbide Tip: The cutting tip features a double-angle cutting edge, delivering sharp penetration and extreme wear resistance. Even under continuous high-temperature hammer drilling, the tip remains intact, preventing overheating and tip failure — a crucial advantage on reinforced concrete and hard aggregates.
Combined with an optimized spiral flute geometry, our bits evacuate dust efficiently, reducing friction and clogging. This keeps the bit cooler and maintains drilling speed for cleaner holes. The secure shank design (SDS Plus / SDS Max locking grooves) ensures zero slip and full power transfer from rotary hammers, improving both safety and performance. Finally, the durable HSS body undergoes special quenching, providing exceptional toughness against bending or fracture — even when drilling through rebar-laden concrete.
YG8 tungsten carbide, double-angle grind for fast penetration & wear resistance.
Deep wide flute removes dust fast, reduces heat & clogging.
Standard SDS locking notches prevent bit drop, max power transfer.
Quenching processed for high toughness, resists bending & breakage.
Common Applications & Problem‑Solving
🏗️ Construction & Civil Engineering
Drilling holes for expansion anchors, concrete screws, chemical anchors. Fast, clean holes in hard concrete & reinforced masonry — reduces bit wear and tool stress.
⚡ Electrical & Plumbing Installations
Conduit, wiring, pipework through walls & floors. Optimized flute clears debris instantly, preventing clogging and ensuring accurate hole placement.
❄️ HVAC & Mechanical Maintenance
Mounting brackets, equipment supports, and ductwork. Long-length bits drill through thick walls in one pass, saving time even in demanding environments.
🛠️ DIY Renovation & Home Improvement
Shelves, fixtures, openings in brick & concrete. Compatible with consumer-grade rotary hammers — professional performance without dull or broken bits.
Real Customer Case: Bulk Order for a European Construction Supply Chain
A major construction supply chain in Germany placed a bulk order with DISLAB Precision for 20,000 pieces of SDS Plus hammer drill bits in various sizes (6mm to 12mm, lengths 110mm to 200mm). The bits were destined for retail stores across the country, catering to both professional tradesmen and DIY customers. Our team provided a comprehensive selection of standard sizes, with each batch undergoing strict quality checks for tip hardness, shank dimensional accuracy, and flute finish. The bits were packaged in retail-ready blister packs with clear labeling. The customer reported that the bits drilled smoothly in various concrete grades, offering a long service life that met their customers’ expectations. The consistent quality and competitive pricing led to a follow-up order for larger SDS Max bits for heavy-duty use.
