Product Description
Milwaukee SHOCKWAVE Insert Bit Hex 3 mm — 25 Pack
Model Number: 48-32-4725
The Milwaukee 48-32-4725 is a 25-pack of SHOCKWAVE Impact Duty Hex 3 mm insert bits — the bulk-quantity format for metric hex driver bits used in HVAC equipment installation, controls and automation equipment, European-standard mechanical assemblies, precision machinery maintenance, and any professional application where metric hex socket head fasteners are a regular part of the installation or service work. The 3 mm hex size is one of the standard metric hex fastener specifications found throughout European-manufactured HVAC equipment, control panels, panel-mounted hardware, and precision mechanical components assembled with metric hex fasteners rather than the inch-size fasteners standard in North American equipment. As commercial HVAC, industrial controls, and precision equipment work increases across North American markets, the need for high-quality metric hex driver bits in professional tool kits has grown substantially for HVAC service technicians, industrial maintenance crews, and equipment installation specialists.
Milwaukee manufactures SHOCKWAVE Impact Duty bits from proprietary steel with multi-zone heat treatment — hard at the driving tip for wear resistance against the repetitive contact stress of metric hex socket engagement, tough through the shank for impact energy absorption without brittle fracture. The small 3 mm hex profile is particularly vulnerable to rounding under impact driver loads because the narrow cross-section of the driver bit's hex engagement surface concentrates driving stress in a small area — SHOCKWAVE's material specification and Shockzone geometry work together to protect this vulnerable small-profile tip from the progressive rounding that renders standard 3 mm hex bits unusable long before SHOCKWAVE bits in the same application. The 25-pack bulk format reduces per-bit purchasing cost for maintenance technicians and service teams who drive 3 mm metric hex fasteners regularly in HVAC, controls, and precision equipment service work.
Available across the full metric hex range from 2.5 mm through 12 mm in both individual and 25-pack bulk formats — see Milwaukee's SHOCKWAVE metric hex bit lineup for all available metric hex sizes.
