MILWAUKEE SDS-MAX

Milwaukee Electric Tool Corporation, founded in 1924 and headquartered in Brookfield, Wisconsin, manufactures heavy-duty power tools and accessories for professional trades. The SDS-Max line consists of rotary hammer bits and core bits engineered for drilling and coring in concrete, masonry, and brick. These tools are used in construction, infrastructure repair, and industrial maintenance where anchor holes, through-holes, and large-diameter penetrations are required. The SDS-Max shank system, standardized under TE-S and TE-Y profiles, transmits higher torque and impact energy than SDS-Plus, making it suitable for hammers in the 5 kg to 16 kg class. Milwaukee's SDS-Max core bits are available in one-piece and two-piece configurations. One-piece core bits, such as the 785X series, combine the shank, body, and cutting head into a single unit. They are designed for dry drilling and do not include a pilot bit; a separate pilot bit and guide plate are required for accurate hole placement. Core diameters in the 785X series range from 1-1/2 in to 5 in, with core body lengths of 3 in and overall lengths of 11-3/8 in or 22 in. The 22 in overall length allows drilling through thick walls or deep concrete sections in a single pass. The SDS-Max shank provides a secure interface with compatible rotary hammers, reducing bit slip and improving energy transfer. Carbide cutting edges are brazed to the steel body, and the flute geometry is designed to clear dust during dry drilling. These bits are intended for use in masonry, concrete, and brick. They are not designed for wet coring or for drilling in steel or wood. 3G Electric supplies the Milwaukee SDS-Max range as part of its industrial equipment catalog. The catalog includes 37 SKUs across the SDS-Max family, covering multiple diameters and lengths. 3G Electric provides logistics support for global delivery, including export documentation and freight coordination. For plant engineers and maintenance managers, 3G Electric can source specific part numbers, such as 48-20-5402 or 48-20-5430, and provide lead-time estimates based on current stock. Procurement specialists can request quotes for single units or bulk orders. The product data available through 3G Electric includes core diameter, overall length, core body length, and manufacturer part number, allowing buyers to match bits to their hammer model and application requirements. Technical support is available to confirm compatibility with specific rotary hammer models and to assist with pilot bit selection. 3G Electric does not manufacture these products; it distributes genuine Milwaukee SDS-Max accessories.

Frequently asked questions

Common questions about MILWAUKEE SDS-MAX from 3G Electric.

What is the difference between the Milwaukee SDS-Max 785XT6 and 785XU0 core bits?

The 785XT6 (MPN 48-20-5402) has a 1-1/2 in core diameter, 3 in core body length, and 22 in overall length. The 785XU0 (MPN 48-20-5430) has a 3-9/16 in core diameter, 3 in core body length, and 22 in overall length. Both are one-piece SDS-Max core bits designed for dry drilling in concrete, masonry, and brick. The primary difference is the core diameter, which determines the size of the hole produced. Neither bit includes a pilot bit; a separate pilot bit and guide plate are required for accurate placement. The 22 in overall length on both models allows drilling through thick sections. Selection depends on the required hole diameter and the available rotary hammer power.

Can Milwaukee SDS-Max core bits be used for wet drilling?

No. The Milwaukee SDS-Max core bits listed, including the 785X series, are designed for dry drilling only. Wet drilling can cause the carbide cutting edges to degrade, lead to improper dust evacuation, and potentially damage the bit or the hammer. For wet coring applications, a different type of core bit with appropriate water management features is required. Always follow the manufacturer's recommendations for the specific bit and application. If you are unsure whether a bit is suitable for your application, consult the product specifications or contact 3G Electric for clarification.

What pilot bit is required for Milwaukee SDS-Max one-piece core bits?

Milwaukee SDS-Max one-piece core bits, such as the 785XT6, 785XU0, and 785XU4, do not include a pilot bit. A separate pilot bit and guide plate are required to center the core bit and prevent wandering during initial penetration. The pilot bit must match the core bit's shank system and the rotary hammer's chuck. Milwaukee offers pilot bits and guide plates as separate accessories. The correct pilot bit diameter depends on the core bit size and the hammer model. Using the wrong pilot bit can result in inaccurate hole placement or damage to the core bit. Consult the rotary hammer manual or contact 3G Electric for assistance in selecting the correct pilot bit.

What is the maximum core diameter available in the Milwaukee SDS-Max 785X series?

The Milwaukee SDS-Max 785X series includes core bits with diameters up to 5 in. For example, the 785XU4 (MPN 48-20-5438) has a 5 in core diameter, 3 in core body length, and 22 in overall length. Larger diameters require a rotary hammer with sufficient power and impact energy to drive the bit efficiently. Always check the rotary hammer's specifications for the maximum recommended core bit diameter. Using a core bit that is too large for the hammer can cause overheating, premature wear, or damage to the tool. The 5 in core bit is intended for large-diameter penetrations in concrete and masonry.

What overall lengths are available for Milwaukee SDS-Max core bits?

Milwaukee SDS-Max core bits in the 785X series are available in two overall lengths: 11-3/8 in and 22 in. The 11-3/8 in length is suitable for standard wall thicknesses and shallower drilling depths. The 22 in length allows drilling through thicker walls or deeper concrete sections in a single pass, reducing the need for extensions. For example, the 785XT7 (2 in core diameter) and 785XU1 (4 in core diameter) have 11-3/8 in overall lengths, while the 785XT6 (1-1/2 in), 785XU0 (3-9/16 in), and 785XU4 (5 in) have 22 in overall lengths. Core body length is 3 in for all listed models.
