Milwaukee SDS-MAX 4-Cutter Carbide Drill Bits for Concrete and Stone Ø28mm / pce

Product

Milwaukee SDS-MAX 4-Cutter Carbide Drill Bit designed for heavy-duty drilling in concrete and stone, with a 28mm diameter and compatible with SDS-MAX rotary hammers.

Specifications

• Four-cutter carbide tip geometry for aggressive material removal and efficient drilling performance
• Three Power Breaker attack blocks generate a splitting effect by creating micro-fractures in concrete
• Sharpened centering point ensures precise axial guidance, preventing drift on smooth surfaces
• Reinforced head design reduces the risk of jamming or deflection when encountering rebar
• Progressive conical tip geometry minimizes friction and optimizes energy transfer from the machine
• High break resistance for extended durability under demanding jobsite conditions
• SDS-MAX shank for secure, tool-free bit insertion and compatibility with SDS-MAX rotary hammers

Usage

Insert the SDS-MAX shank into a compatible rotary hammer. The centering point guides the bit accurately at the start of drilling. The four-cutter carbide head and Power Breaker blocks work together to penetrate concrete and stone efficiently, reducing heat buildup and operator fatigue.

FAQ

1. Is this bit compatible with all SDS-MAX rotary hammers? — Yes, the SDS-MAX shank is a standardized interface compatible with all rotary hammers featuring an SDS-MAX chuck.
2. Can this bit be used on reinforced concrete? — Yes, the reinforced head is specifically designed to reduce deflection and jamming when the bit contacts steel rebar within concrete.
3. What is the diameter of this drill bit? — This drill bit has a diameter of 28mm, suitable for large-diameter holes in concrete and stone applications.
4. What does the 4-cutter design offer compared to standard bits? — The four cutting edges increase material contact per rotation, improving drilling speed and reducing wear compared to standard 2-cutter bits.
5. Is this bit suitable for dry drilling only? — Yes, this bit is designed for dry drilling applications in concrete and stone when used with an SDS-MAX rotary hammer in hammer drill mode.
