Simpson 5/8" x 8" 2-Cutter Head SDS-Plus Carbide Drill Bit is a premium, professional-grade rotary hammer drill bit engineered for precision concrete, masonry, and hard material drilling. Built to the highest industry standards from hardened steel with a carbide-tipped 2-cutter head, this SDS-Plus shank bit delivers reliable performance across a wide range of rotohammer applications - giving contractors and tradespeople a durable, fast-drilling solution that holds up under demanding jobsite conditions.

Key Features

• Carbide-Tipped 2-Cutter Head - provides aggressive cutting action in concrete and masonry, reducing drilling time and bit wear compared to standard tips
• SDS-Plus Shank - locks securely into SDS-Plus rotary hammers for quick, tool-free bit changes and efficient energy transfer from the hammer mechanism to the cutting tip
• 5/8" Diameter with 6" Drilling Depth - sized for anchor bolt and fastener holes that meet precise tolerance requirements, ensuring correct fit for Simpson Strong-Tie anchors and similar hardware
• 8" Overall Length - provides reach for deeper applications and allows the user to clear debris from the hole during drilling without repositioning
• Hardened Steel Construction - the shank and body resist bending and fatigue under rotary hammer impact, extending the working life of the bit on tough substrates
• Manufactured in Germany to the Highest Industry Standards - tight dimensional tolerances mean the bit produces consistently accurate hole sizes, which is critical for anchor installation load ratings
• Proprietary Features Enhancing Durability and Drilling Speed - engineered improvements over commodity bits translate to fewer bit replacements and faster hole completion on the job

Why This Product

• Designed specifically to meet the precise tolerance requirements of Simpson Strong-Tie anchor and fastener systems - using the correct bit helps ensure installed anchors perform to their rated values
• The 2-cutter carbide head and hardened steel body work together to handle demanding drilling tasks in concrete and masonry without sacrificing speed or longevity
• Compatible with all current and older SDS-Plus rotohammers from leading tool brands including Bosch, DeWalt, Makita, Milwaukee, Hilti, and many others - no adapters or special tools required
• Professional-grade quality produced under rigorous manufacturing standards means this bit is built for repeated, heavy-duty use rather than occasional or light-duty applications

Frequently Asked Questions

What rotary hammers is this SDS-Plus bit compatible with?

This bit's SDS-Plus shank is compatible with all current and older SDS-Plus rotohammers from AEG, Black & Decker, Bosch, DeWalt, Hitachi, Hilti, Kango, Makita, Metabo, Milwaukee, Porter Cable, Ramset, Red Head, Ryobi, and Skil, among others. If your rotary hammer uses an SDS-Plus chuck, this bit will fit and lock in securely.

What is the maximum drilling depth this bit can achieve?

This bit has a drilling depth of 6 in., meaning it can produce anchor or fastener holes up to 6 in. deep in concrete or masonry substrates. The 8 in. overall length provides the necessary shank engagement and clearance to reach that full depth without obstruction.

Why is using a correctly sized drill bit important for anchor installations?

Anchor systems - including Simpson Strong-Tie anchors - are engineered to work within precise hole diameter tolerances. Using a bit that meets those tolerances helps ensure the anchor seats correctly and can achieve its rated load values. This 5/8 in. carbide bit is designed to meet the precise tolerance requirements specified for compatible Simpson Strong-Tie anchor products.

What is the difference between a 2-cutter head and other head configurations?

A 2-cutter head features two carbide cutting edges that chip and remove material as the bit rotates and hammers. Simpson also offers Quad Head configurations with additional cutting edges for different drilling applications. The 2-cutter design on this bit provides reliable performance for standard concrete and masonry anchor hole drilling tasks.
