Sabre Tools 7/8X6” SDS Plus Bit, 2-Pack
The Sabre Tools 7/8” SDS Plus drill bit set includes two bits of 6″ flute length with an 8″ overall length, designed for high-demand masonry tasks. The carbide-tipped heads deliver durability when drilling in brick, stone, and concrete. Compatible with all SDS-Plus rotary hammer drills, including Bosch, DeWalt, Hitachi, Hilti, Makita, and Milwaukee models. This set emphasizes reliable performance in everyday concrete drilling and anchor hole preparation.
Diablo Rebar Demon 7/8″ SDS-Plus 4-Cutter Bit
Diablo’s Rebar Demon features a full carbide head with four cutters and a tri-metal fusion weld. The design aims to withstand intense heat and heavy impact, delivering up to 7X longer life than standard two-cutter bits. Precision tips and optimized flute geometry help manage dust and keep the carbide head cooler, improving stability and hole accuracy in reinforced concrete and masonry applications.
DKIBBITH 7/8″ x 12″ Long SDS-Plus Bits (2-Pack)
DKIBBITH provides two 7/8″ carbide-tipped drill bits at 12″ length for long-hole drilling in concrete, brick, cement, and stone. The bits are designed for fast, precise drilling and broad compatibility with SDS-Plus rotary hammers from top brands. The extended length is ideal for deep anchor holes and pass-through installations in masonry structures.
Bosch HC2146 7/8″ x 10″ SDS-Plus Bulldog Bit
The Bosch HC2146 offers a two-cutters head that reduces drilling resistance and speeds up hole creation. A centered tip supports precise hole placement, and wear marks indicate bit life. This option is well-suited for general concrete drilling, anchor holes, and situations requiring dependable speed and alignment in SDS-Plus drills.
Sabre Tools 7/8″ x 12″ SDS-Plus Bit (Version 2)
This longer Sabre Tools bit (Version 2) combines a 7/8″ diameter with a 12″ total length, optimized for deep masonry holes in brick, stone, and concrete. The carbide-tipped design supports extended use in demanding applications, while maintaining compatibility with common SDS-Plus rotary hammers across major brands.
Buying Guide: Key Purchase Considerations
- Bit length and reach: Longer bits are ideal for deep holes or through-holes, while shorter bits provide quicker drilling and less wobble in shallow tasks. Consider total length and flute depth to match your project needs.
- Cutter configuration: Two-cutters provide fast drilling in standard concrete, while four-cutters offer smoother cuts through reinforced materials and heavy aggregate. For rebar-heavy concrete, carbide heads and multi-cutter designs tend to last longer.
- Carbide durability: Carbide-tipped bits resist heat and impact. Look for models advertised with higher heat tolerance and robust welding (e.g., tri-metal fusion) when you expect heavy-duty use or rebar contact.
- Compatibility: Ensure SDS-Plus compatibility with your hammer model (Bosch, DeWalt, Makita, Milwaukee, Hilti, etc.). Most options listed are designed to fit standard SDS-Plus rotary hammers.
- Application scope: Choose bits based on target material—brick, stone, concrete, cement block, or reinforced concrete. For deep anchor holes, select longer bits with stable cutting tips.
- Maintenance and wear indicators: Some bits include wear marks or coatings that help gauge life. This is helpful for busy job sites where consistent performance matters.
- Cost vs. longevity: Higher upfront cost may be offset by longer life in tough masonry tasks. If you frequently drill through reinforced concrete, favor multi-cutter carbide bits with durable heads.
- Brand ecosystem: While not always necessary, staying within a single brand’s SDS-Plus ecosystem can simplify tool compatibility and speed up project setup.
