Product Description
Milwaukee SHOCKWAVE Insert Bit Phillips #3 — 25 Pack
Model Number: 48-32-4113
The Milwaukee 48-32-4113 is a 25-pack of SHOCKWAVE Impact Duty Phillips #3 insert bits — the bulk-quantity format for contractors and tradespeople who drive large-diameter Phillips #3 fasteners regularly with cordless impact drivers and need a cost-effective per-bit supply for production-pace fastener work. Phillips #3 is the drive specification for larger construction screws, lag bolts, heavy structural fasteners, and high-torque wood fastening applications where the smaller #2 drive size would cam out under the driving torque required for full fastener seating in dense wood, engineered lumber, and structural connections. Milwaukee manufactures SHOCKWAVE Impact Duty bits from a proprietary steel alloy processed through a multi-zone heat treatment that engineers hard surface material at the driving tip for wear resistance and cam-out prevention, while the shank material retains the higher toughness needed to absorb the repetitive impact energy from each impact driver hammer cycle without brittle fracture.
The Shockzone torsional compliance feature machined into the SHOCKWAVE bit shank is the engineering element that enables the 10x life advantage over standard driver bits under impact driver use. Each impact driver strike transmits a peak torsional energy spike that exceeds the sustained driving torque by a significant margin — standard bits transmit this full peak stress to the driving tip, progressively fatiguing the tip material until cracking and rounding failure occurs. The Shockzone's controlled elastic deformation absorbs each peak energy spike before it reaches the tip, distributing the energy over a longer time period and dramatically reducing the peak stress at the tip material. The 25-pack bulk format reduces per-bit cost significantly versus individual unit purchasing, making it the standard procurement approach for electrical contractors, HVAC installers, and general contractors who drive #3 Phillips fasteners in volume across multiple projects.
Also available in 2-in. power bit length for applications requiring extended reach on countersunk or deeply recessed Phillips #3 fastener locations where the standard 1 in. insert length is insufficient for the driver chuck to clear the work surface.
