Milwaukee 3151-21 M12 Auto Shop Borescope w/ Wi-Fi File Sharing Kit (1) 2AH

Built for busy service bays, the Milwaukee 3151-21 M12 Auto Shop Borescope streamlines how technicians inspect, document, and share repair findings. A 5.5″ HD touchscreen display gives a sharp, color image that makes identifying carbon buildup, scoring, and hairline cracks more reliable than small, low-resolution screens. Front and side cameras with adjustable LED lighting expand viewing angles inside tight passages, while 4X digital zoom helps confirm details without rerouting the cable. The 5 mm (0.197″) waterproof camera cable reaches areas common in modern engines—glow plug holes, injector ports, and intake runners—where larger probes can’t go.

For documentation, the on-board tools let users draw on images, add audio notes, type text, and trim video clips so information is clear before sharing. Connect to shop Wi-Fi to send photo or video files from the tool for estimates and warranty claims. HEAT SENSE™ temperature alerts help prevent cable damage on hot components, and the field-replaceable 5′ camera cable reduces downtime if the probe is worn or damaged. Powered by the M12 platform and supplied with a CP2.0 battery, charger, 32GB SD card, and USB-C cord, this inspection camera is ready for daily automotive diagnostics.

Technicians, fleet managers, and diesel specialists benefit from quicker diagnostics and cleaner documentation. Instead of moving files through a separate device, Wi-Fi sharing pushes images and video straight to estimates, work orders, and emails while the vehicle is still on the lift. The 5.5″ HD touchscreen and 4X zoom help catch small defects that would otherwise require teardown to confirm, and the dual-camera tip speeds checks around valves or ports without withdrawing and reinserting the probe. For shops that run multiple bays, the field-replaceable cable and M12 battery keep the borescope available throughout the day with minimal interruptions.
