Product Description
Milwaukee SDS Max Bit 9/16 in. x 7-1/2 in. x 13 in.
Model Number: 48-20-3910
The Milwaukee 48-20-3910 is an SDS Max carbide drill bit in 9/16 in. diameter with a 7-1/2 in. working length and 13 in. overall length — a mid-size anchor drilling bit for the SDS Max platform used in medium-duty structural anchor installations and through-wall penetrations requiring the higher energy delivery of SDS Max rotary hammers in harder commercial concrete conditions. The SDS Max shank transmits significantly more impact energy per stroke than the SDS+ standard — at 9/16 in. diameter in hard commercial concrete, the SDS Max energy level maintains productive drilling speed and consistent penetration rate where SDS+ hammers experience reduced efficiency due to the higher drilling resistance of dense concrete aggregate. Milwaukee SDS Max bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized flute geometry for efficient debris evacuation through the 7-1/2 in. working depth.
The 13 in. overall length provides the reach needed for through-wall penetrations in standard CMU block construction with additional finish thickness, for structural anchor installations requiring embedment depths beyond what standard-length bits achieve, and for drilling positions where the hammer must be positioned away from the wall surface due to structural obstructions. The 9/16 in. diameter accommodates specific anchor systems and through-bolt sizes specified for medium-duty structural connections where the adjacent 1/2 in. and 5/8 in. sizes are either too small or larger than necessary for the connection's load requirements. The SDS Max shank provides positive anti-rotation locking engagement in the hammer's tool holder for secure retention during heavy-duty anchor drilling operations.
