About MILWAUKEE SDS

Milwaukee Electric Tool Corporation, founded in 1924 and headquartered in Brookfield, Wisconsin, is a manufacturer of heavy-duty power tools and accessories. The company's SDS (Special Direct System) line encompasses rotary hammers, drill bits, chisels, and related accessories that use the SDS-Plus and SDS-Max bit-retention systems. These systems are standardized interfaces for hammer drilling and chiseling in concrete, masonry, and stone. 3G Electric supplies the Milwaukee SDS line globally, offering OEM components for maintenance, repair, and operations across industries that require reliable holemaking and demolition tools.

The Milwaukee SDS product families include cordless rotary hammers, such as the 18V DC L-shape model (MPN 2717-22HD) that delivers 5.1 ft-lb of impact energy and up to 3,000 blows per minute, with a maximum drilling capacity of 1 9/16 inches in concrete. The line also features a range of SDS-Plus and SDS-Max drill bits for concrete and masonry, available in diameters from 5/32 inch to larger sizes, with overall lengths up to 16 inches and maximum drilling depths up to 14 inches. Specialized bits include dust-extraction hollow core bits that connect to vacuum systems to capture debris at the source, and chisel bits for scaling, chipping, and demolition tasks. Chisel options include bull point and scaling chisels with shank diameters of 45/64 inch and overall lengths up to 26 11/16 inches. Additionally, adapter shanks allow the use of thick wall core bits with SDS-Max rotary hammers, expanding the tool's capability for core drilling in concrete, masonry, and stone.

These tools are used in construction, concrete cutting, anchor installation, and general demolition. The SDS system enables quick bit changes and efficient power transfer from the hammer to the bit. Milwaukee designs its SDS accessories for durability and performance in demanding applications, with features such as carbide tips for extended life and flute designs for rapid dust removal. 3G Electric supports the Milwaukee SDS line by stocking genuine OEM parts and accessories, providing global sourcing, and offering technical specifications to help procurement and maintenance teams select the correct components for their equipment. With a focus on industrial applications, 3G Electric ensures that customers can obtain the exact Milwaukee SDS items needed for their operations, from standard drill bits to specialized chisels and adapters.

Common Applications

  • Concrete anchor installation — Milwaukee SDS-Plus drill bit 7/32 in (MPN 48-20-7426) for drilling deep holes in concrete and masonry.
  • Dust-controlled drilling in occupied spaces — Milwaukee SDS-Plus dust-extraction hollow core bit (MPN 48-20-2118) with vacuum connection.
  • Heavy-duty demolition — Milwaukee SDS-Max bull point chisel (MPN 48-62-4062) for breaking concrete and stone.
  • Surface preparation — Milwaukee SDS-Plus scaling chisel (MPN 48-62-4086) for removing mortar, tile, and masonry from surfaces.
  • Cordless drilling in remote areas — Milwaukee 18V SDS-Max rotary hammer (MPN 2717-22HD) for drilling up to 1 9/16 in in concrete.
  • Core drilling with rotary hammers — Milwaukee SDS-Max adapter shank (MPN 48-03-3573) to use thick wall core bits with SDS-Max hammers.

Frequently asked questions

Common questions about MILWAUKEE SDS from 3G Electric.

What is the difference between Milwaukee SDS-Plus and SDS-Max drill bits?

SDS-Plus and SDS-Max refer to the shank design and size. SDS-Plus bits have a smaller shank diameter (typically 10 mm) and are used in lighter rotary hammers, while SDS-Max bits have a larger shank (typically 18 mm) for heavier hammers with higher impact energy. Milwaukee offers both types: SDS-Plus bits are common for drilling holes up to 1 inch in diameter, and SDS-Max bits handle larger diameters and more demanding applications. The choice depends on the rotary hammer's chuck type and the required drilling capacity.

What is the maximum drilling depth of Milwaukee SDS-Plus drill bits?

Milwaukee SDS-Plus drill bits are available in various lengths. For example, the 7/32-inch bit (MPN 48-20-7426) has a maximum drilling depth of 14 inches and an overall length of 16 inches. The 3/16-inch bit (MPN 48-20-7412) offers a 6-inch maximum drilling depth with an 8-inch overall length. These depths are suitable for anchor installation and through-hole drilling in concrete and masonry. Always select a bit with a maximum drilling depth that exceeds the required hole depth to allow for dust clearance.

Can Milwaukee SDS-Max chisels be used in SDS-Plus rotary hammers?

No. SDS-Max and SDS-Plus shanks are not interchangeable. SDS-Max chisels, such as the bull point chisel (MPN 48-62-4062), have a larger shank diameter (45/64 inch) and are designed for SDS-Max rotary hammers. SDS-Plus chisels, like the scaling chisel (MPN 48-62-4086), have a smaller shank and fit SDS-Plus hammers. Attempting to use a chisel in the wrong chuck can damage the tool and is unsafe. Always match the chisel's shank type to the rotary hammer's chuck system.

What is the purpose of the Milwaukee SDS-Plus dust-extraction hollow core bit?

The Milwaukee SDS-Plus dust-extraction hollow core bit (MPN 48-20-2118) is designed to capture drilling dust at the source when connected to a compatible vacuum system. It has a 3/4-inch diameter, a 9 1/2-inch maximum drilling depth, and a 14-inch overall length. This reduces airborne silica dust, which is a health hazard, and keeps the work area cleaner. It is commonly used in concrete and masonry drilling where dust control is required, such as in occupied buildings or confined spaces.

What is the impact energy of the Milwaukee 18V cordless SDS-Max rotary hammer?

The Milwaukee 18V cordless SDS-Max rotary hammer (MPN 2717-22HD) delivers 5.1 ft-lb of impact energy and operates at up to 3,000 blows per minute. It has a maximum drilling capacity of 1 9/16 inches in concrete. This model uses an 18V DC power source with an 8.0 Ah battery, providing cordless convenience for heavy-duty drilling and chiseling tasks. It is suitable for applications where portability and power are both required, such as remote job sites or overhead work.

What adapter is needed to use Milwaukee thick wall core bits with an SDS-Max rotary hammer?

The Milwaukee SDS-Max adapter shank (MPN 48-03-3573) is required to attach Milwaukee thick wall core bits to compatible SDS-Max rotary hammers. This adapter has an SDS-Max connection on one end and accepts the core bit on the other. It allows core drilling in concrete, masonry, and stone with an SDS-Max hammer, expanding the tool's versatility. Ensure the rotary hammer is set to hammer mode only if the core bit is designed for hammering; otherwise, use rotation-only mode as recommended by the core bit manufacturer.
