Complete Specifications & Features
The Milwaukee® M12 4-in-1 Installation Drill represents a breakthrough in compact drilling technology.
Power & Performance
The heart of the M12 4-in-1 Installation Drill is Milwaukee®'s POWERSTATE™ brushless motor, delivering an impressive 300 in-lbs of maximum torque—more than enough power for most installation applications. The motor spins at up to 1,600 RPM, providing efficient drilling and driving performance while extending tool life through reduced friction and heat generation.
REDLINK PLUS Intelligence protects your investment by monitoring tool and battery performance in real-time. This advanced system prevents overloading and overheating, ensuring consistent performance even during demanding applications. The electronic management also maximizes battery life by optimizing power delivery based on the specific task at hand.
Size & Weight
At just 5.12 inches wide and weighing only 2.0 lbs with an attached battery, this drill prioritizes maneuverability without compromising capability. The compact dimensions allow it to fit between standard 16" stud spacing with room to spare, while the lightweight design reduces fatigue during extended overhead work.
The tool features a unique inline grip positioned at the back, providing ultimate control and allowing access to areas where traditional drill grips would interfere with surrounding obstacles. The flat top design enables flush drilling against surfaces, eliminating the clearance issues common with conventional drill profiles.
Four Attachment Heads
- 3/8" Chuck Attachment: The all-metal 3/8" chuck handles standard drill bits and provides the versatility needed for general drilling applications. Its robust construction ensures reliable bit retention even under high-torque conditions.
- 1/4" Hex Attachment: Perfect for driving screws and bolts, this attachment accepts standard hex-shank bits and provides direct power transfer for efficient fastening operations.
- Offset Attachment: The offset head delivers ultimate access to tight corners and confined spaces. Its angled design prevents damage to finished materials during fastening operations, making it ideal for cabinet installation and finish work.
- Right Angle Attachment: This attachment provides efficient drilling and fastening at 90-degree angles, perfect for accessing areas where straight-line drilling is impossible. It can also combine with the other attachments for even greater versatility.
All four attachments connect to the tool in 16 different positions, creating nearly limitless angle combinations. This positioning system ensures you can find the right approach for virtually any installation challenge.
The Milwaukee® M12 4-in-1 kit includes four versatile attachments, dual batteries, and a charger, offering unmatched flexibility for drilling and fastening in tight spaces.
Battery Compatibility & Features
The M12 4-in-1 Installation Drill is fully compatible with the entire M12 REDLITHIUM battery system, including compact 1.5Ah batteries for minimum weight and extended capacity options up to 6.0Ah for maximum runtime. The kit includes two M12 REDLITHIUM CP2.0 battery packs, providing balanced performance and runtime for most applications.
A magnetic bit holder on the front of the tool securely holds multiple bits, enhancing productivity by keeping frequently used accessories within reach. This eliminates time wasted searching through tool bags or returning to storage for different bits.

Applications & Use Cases
The Milwaukee® M12 4-in-1 drill driver makes tight electrical and HVAC installs simple with its versatile attachments.
Electrical Installation
Electricians particularly appreciate the M12 4-in-1's ability to access junction boxes, panel enclosures, and tight conduit runs. The offset attachment excels at installing outlets and switches in finished walls without damaging drywall or trim work.
HVAC Applications
HVAC technicians use this tool for accessing ductwork connections, mounting equipment in cramped mechanical rooms, and performing maintenance in areas where larger tools won't fit. The right-angle attachment is especially valuable for accessing fasteners behind furnaces and air handlers.
Cabinet & Furniture Installation
Cabinet installers rely on the precision control and compact size for mounting hinges, drawer slides, and hardware in tight spaces. The offset attachment prevents marring finished surfaces, while the various angles allow proper fastener placement even in corner cabinets.
Automotive Repair
In automotive applications, the tool's compact size and multiple angles provide access to engine bay components, interior panels, and undercarriage areas where standard drills are too bulky. The 300 in-lbs torque handles most automotive fasteners with ease.
MRO (Maintenance, Repair, Operations)
Maintenance professionals appreciate having one tool that adapts to multiple scenarios. Whether working on machinery, building systems, or equipment repair, the 4-in-1 design reduces the number of tools needed for most tasks.

With 300 in-lbs of torque and a POWERSTATE brushless motor, the M12 4-in-1 handles most installation applications with ease. While it's not designed for heavy construction tasks like timber framing, it excels at electrical work, cabinet installation, HVAC mounting, and automotive repair where access is more important than raw power.
