Milwaukee Single Bit Holder
Model Number: 43-72-0046
The Milwaukee 43-72-0046 is a genuine OEM Single Bit Holder replacement component for compatible Milwaukee power tools — a precision-machined or formed component that retains a single driver bit or tool accessory in the correct position within the tool's mechanism, providing the positive retention and accurate positioning needed for reliable accessory engagement during tool operation. Bit holder components in Milwaukee tools secure insert bits, driver bits, and small accessories at the tool's working interface, maintaining the bit's alignment with the drive axis for accurate, consistent torque transmission and preventing the bit from backing out or disengaging during driving operations. When a bit holder wears, cracks, loses its spring retention force, or becomes damaged from impact loading, the bit it retains loses reliable retention — bits may slip, back out during driving, or engage inconsistently, compromising driving performance and potentially damaging the fastener head or work surface.
Using a genuine Milwaukee OEM single bit holder ensures the correct dimensions, material specification, and retention force geometry for reliable bit engagement in the specific tool application. Bit holder specifications — including the bore diameter for the bit shank, retention mechanism geometry, and spring or detent force — are specific to each tool model. Always verify your specific Milwaukee tool's model number and serial number at milwaukeetool.com or reference the illustrated service parts diagram to confirm the correct bit holder part number before ordering, as specifications vary by tool model and production revision.
