SDS (Special Direct System) hammer drill attachments are designed to enhance the performance and efficiency of rotary hammer drills, which are essential tools for drilling into concrete, masonry, and other hard materials. These attachments come in various types, including drill bits, chisels, core bits, and rebar cutters, each catering to specific drilling needs and applications.
Key Features and Benefits
SDS Plus and SDS Max Drill Bits
- Carbide-Tipped for Maximum Performance: SDS Plus and SDS Max drill bits feature carbide tips, which provide exceptional durability and extended drilling life compared to standard steel drill bits.
- Diverse Diameter and Length Options: SDS Plus drill bits are available in diameters ranging from 5/32″ to 1″ and usable lengths from 2″ to 21″. SDS Max drill bits come in diameters from 1″ to 1-3/8″ and usable lengths from 8″ to 30-3/4″.
- Efficient Drilling in Concrete and Masonry: The unique SDS shank design and hammer action of rotary hammer drills allow these drill bits to efficiently penetrate and drill through concrete, brick, and other masonry materials.
Chisels and Core Bits
- Heavy-Duty Design for SDS Max Drills: SDS Max chisels and core bits are engineered for use with air and hydraulic SDS Max rotary hammer drills, which are typically more powerful and durable than their SDS Plus counterparts.
- Variety of Chisel Styles: SDS Max chisels are available in various styles, including flat, moil point, scaling, and slotting, to accommodate different chiseling and demolition tasks.
- Precise Core Drilling: SDS Max core bits enable precise and clean core drilling in concrete, masonry, and other hard materials, making them ideal for applications such as installing electrical conduits or plumbing pipes.
Rebar Cutters
- Efficient Rebar Cutting: SDS hammer drill attachments include rebar cutters designed specifically for cutting through reinforcing steel bars (rebar) embedded in concrete and masonry structures.
- Time-Saving and Precise Cutting: Rebar cutters allow users to quickly and accurately cut through rebar, saving time and effort compared to using traditional cutting tools.
Compatibility and Usage
SDS Plus vs. Standard SDS Drill
- Incompatibility: SDS Plus drill bits are designed to be used exclusively with SDS Plus rotary hammer drills and are not compatible with standard SDS drills due to differences in shank size and design.
SDS Max Bits with SDS Plus Hammer Drill
- Incompatibility: SDS Max drill bits cannot be used with SDS Plus hammer drills, as the shank size and design are not compatible between the two systems.
SDS Drill Bits with Standard Power Drills
- Incompatibility: SDS drill bits, whether SDS Plus or SDS Max, are not compatible with standard power drills due to the unique shank and chuck design required for rotary hammer drills.
