The MILWAUKEE 43-56-0400 is a replacement punch guide designed for use with compatible Milwaukee punch driver systems. A punch guide controls the alignment and travel of the punch during knockout operations, ensuring clean, accurate cuts through metal electrical enclosures, panels, and conduit bodies. This part is a direct OEM-style replacement intended for service technicians and electricians performing maintenance or repair on Milwaukee punch driver tooling assemblies.
Punch guides are used in electrical and industrial trade applications where precision hole-making in sheet metal or steel enclosures is required. This guide is suited for service environments where worn or damaged punch guide components need replacement to restore tool performance and maintain safe, accurate operation.
Designed as an OEM-style replacement punch guide for compatible Milwaukee punch driver tool systems. Verify fitment against your specific Milwaukee punch driver model before installation.
Installation should be performed by a qualified electrician or tool service technician familiar with Milwaukee punch driver equipment. Disconnect the tool from its power source and release any stored hydraulic or mechanical pressure before disassembling the punch assembly. Refer to the Milwaukee service documentation for your specific punch driver model to confirm proper component orientation and torque procedures. Follow all applicable NEC guidelines when performing work on electrical enclosures.
