Key Features
Overview
The Milwaukee 3150-20 M12 Auto Technician Borescope is a cordless inspection camera built for automotive diagnostics in tight, hard-to-see spaces. This is a borescope designed for inspecting internal engine areas, locating damage, and documenting problems in passenger, light truck, and diesel applications. Model Number 3150-20. If your work involves checking glow plug holes, fuel injector ports, or other narrow passages without major disassembly, this tool is built for that job.
What sets this inspection camera apart is access. Milwaukee pairs a 5 mm camera head with a 3 ft camera cable optimized for rigidity, so the cable is small enough to get into narrow openings but still controlled enough to steer where you need it. That combination matters on the job because a camera that fits but flops around is just as frustrating as one that never reaches the area in the first place.
The viewing setup is made for actual diagnostic work, not just casual inspection. You get front and side view cameras for broader application coverage, plus 5 levels of adjustable LED brightness to light up dark cavities and metal surfaces. Add in 4-level zoom adjustment and high-definition photo and video capture, and the tool gives you a better shot at identifying hairline cracks, wear, and internal condition without guessing.
The 4.3 inch rotatable screen makes the Milwaukee 3150-20 M12 Auto Technician Borescope easier to use in awkward engine bays and underhood spaces. Instead of fighting the display angle while holding the cable in position, you can rotate the screen to match the inspection angle. That sounds small until you are leaned over a fender trying to keep a clear image on screen while navigating around hoses, wiring, and brackets.
Milwaukee also addressed two real-world ownership issues: heat and downtime. HEAT SENSE temperature alert technology warns the user and shuts the tool down if the inspection area is too hot for safe camera use, helping protect the cable from damage. When the cable does wear out, it is field-replaceable, so you are not stuck replacing the entire unit just because the most exposed part of the tool took the hit.
On the file management side, this borescope captures photo and video and lets you export through the included 32 GB SD card. That is useful for documenting findings, showing customers or service managers what you found, and keeping a record before and after repairs. For techs doing repeat diagnostic work, being able to save and share what the camera sees is a practical advantage, not a gimmick.
Because it runs on the Milwaukee M12 battery system, this cordless borescope fits into an existing M12 setup without adding another battery platform to the truck or shop. If you already own M12 batteries and chargers, this tool drops right into that system. If you do not, this is sold as tool only, so plan on battery and charger separately.
Who should buy it? Automotive technicians first. If you regularly diagnose engine issues, inspect tight internal passages, or need clear visual confirmation before taking things apart, this is the kind of inspection camera that earns its keep. Serious diesel techs, independent repair shops, and mobile mechanics will get the most value out of it. For general household inspection, it is more specialized than most people need. For automotive work, it is right on target.
See Problems Without Tearing Everything Apart
This cordless borescope is built to give technicians a clear look into engine areas that are difficult to access with the naked eye. Instead of guessing or disassembling first, you can inspect the area, confirm the issue, and move forward with better information.
- Optimized for passenger vehicle, light truck, and diesel inspection work
- High-definition photo and video capture helps document findings for repair decisions
Reach Into Narrow Engine Passages
The small 5 mm camera head and 3 ft rigid cable are the reason this inspection camera makes sense for automotive techs. It is designed to reach glow plug holes and fuel injector ports where bulkier cameras are a dead end.

Pro Tip
Use the front camera to navigate down the passage, then switch to the side view once you are at depth to inspect wall condition and crack lines. If HEAT SENSE gives you a warning, let the area cool instead of forcing the inspection, because cooked camera cables get expensive fast.

Tool Nut's Take
Milwaukee 3150-20 M12 Auto Technician Borescope Gets Where Other Inspection Cameras Quit
If you are an automotive tech who needs real access inside engines and tight passages, this is a purpose-built borescope that makes diagnosis faster and a whole lot more certain.
- Who it's for: Automotive technicians, diesel techs, and serious repair shops that need to inspect internal engine areas without unnecessary teardown.
- Why it stands out: The 5 mm camera head, front and side viewing, rotatable 4.3 inch screen, and M12 battery compatibility make it more job-ready than a basic general-purpose inspection camera.
- Worth knowing: This is a tool-only setup, so bring your own M12 battery and charger. If you already run M12, that is a non-issue. If you do not, factor that in.
