Milwaukee M18 FUEL 4-1/2-Inch–6-Inch Variable Speed Braking Grinder, Paddle Switch with ONE-KEY Kit
Product Overview
The Milwaukee M18 FUEL 4-1/2-Inch–6-Inch Variable Speed Braking Grinder, Paddle Switch with ONE-KEY Kit (3672-22) is a professional cordless angle grinder designed for demanding metalworking, cutting, grinding, and surface-preparation applications. It combines a POWERSTATE Brushless Motor, four selectable speed settings, RAPIDSTOP braking, electronic clutch protection, and ONE-KEY connectivity in a cordless platform.
The grinder produces up to 9,000 RPM and is engineered to deliver power comparable to a 13A corded grinder. Its variable-speed control allows users to select between 3,000 and 9,000 RPM, making it easier to match tool speed to the material and accessory being used.
The kit includes two M18 REDLITHIUM FORGE XC8.0 batteries, an M18/M12 Rapid Charger, guards, side handle, wrench, and contractor bag, providing a complete setup for professional jobsites.
Key Features
POWERSTATE Brushless Motor
The POWERSTATE Brushless Motor delivers up to 9,000 RPM and provides sustained power for demanding grinding and cutting applications. Milwaukee rates the grinder's performance at the equivalent of a 13A corded grinder.
Four-Speed Variable Control
Four selectable speed settings allow the operator to choose speeds from 3,000 to 9,000 RPM. This provides greater control when working with different metals, materials, and accessories where maximum speed is not always appropriate.
RAPIDSTOP Brake
The RAPIDSTOP Brake is designed to stop most abrasive wheels in less than 2 seconds, allowing the grinder to be set down more quickly after releasing the paddle switch.
Electronic Clutch and Overload Protection
An electronic clutch helps provide kickback protection, while overload protection is designed to help protect the motor during demanding applications.
ONE-KEY Connectivity
ONE-KEY allows the grinder to connect wirelessly to a smartphone for tool customization, tracking, and management. This can be particularly useful for contractors managing larger tool inventories across multiple jobsites.
Paddle Switch Design
The non-locking paddle switch provides convenient operation from different hand positions. Combined with the streamlined grip and anti-vibration side handle, the design is intended to improve control and comfort during extended use.
4-1/2-Inch to 6-Inch Capacity
The grinder accepts compatible accessories from 4-1/2 to 6 inches, giving users flexibility for both smaller grinding tasks and applications requiring a larger 6-inch disc. The 5/8"-11 spindle accommodates common grinding accessories.

Battery and Runtime
The kit's two M18 REDLITHIUM FORGE XC8.0 batteries are designed to provide the high-output capability needed for demanding M18 applications. Milwaukee describes the XC8.0 as delivering HIGH OUTPUT HD12.0 power in a smaller package, while also providing its longest life compared with REDLITHIUM batteries.
When paired with an M18 REDLITHIUM FORGE XC8.0 battery, Milwaukee states that the grinder can deliver up to 135 cuts per charge in specified demanding cutting applications. Actual results vary with the material, wheel, battery condition, technique, and application.
Applications
The 3672-22 is designed for a wide range of professional metalworking tasks, including:
Metal cutting
Grinding
Weld cleanup
Surface preparation
Material removal
Deburring
Fabrication
Construction
Maintenance and repair
Automotive and equipment work
General metalworking
The variable-speed function is especially useful when an application or accessory calls for more controlled wheel speed rather than continuous operation at maximum RPM.
Benefits for Professional Users
Cordless 13A-class performance: The grinder provides Milwaukee's stated equivalent of 13A corded-grinder power without requiring an extension cord.
Greater speed control: Four speed settings from 3,000 to 9,000 RPM allow users to adjust performance to the application.
Fast accessory stopping: RAPIDSTOP braking can stop most abrasive wheels in under two seconds.
Improved control and protection: The electronic clutch, overload protection, paddle switch, and anti-vibration side handle are designed to make demanding grinding work more manageable.
Tool management through ONE-KEY: Contractors can use ONE-KEY to customize, track, and manage the grinder, adding an additional layer of inventory and tool-control capability.
Complete battery kit: Two XC8.0 batteries and a Rapid Charger are included, so users can put the cordless grinder to work without purchasing batteries separately.
Important Configuration Note
The exact kit model is 3672-22, while the bare grinder is 3672-20. The 3672-22 includes two 48-11-1881 M18 REDLITHIUM FORGE XC8.0 batteries and a 48-59-1808 M18/M12 Rapid Charger.
This model should not be confused with the 3670-22, which is the non-variable-speed M18 FUEL 4-1/2"-6" Braking Grinder Paddle Switch Kit. The 3672-22 specifically adds four-mode variable-speed control and ONE-KEY connectivity.
Why Choose This Grinder?
The Milwaukee M18 FUEL 3672-22 is a strong choice for professionals who want the flexibility of a 4-1/2"-6" cordless grinder without giving up high-speed performance or control. Its variable-speed system expands its usefulness across different grinding and cutting applications, while RAPIDSTOP, electronic clutch protection, and ONE-KEY add practical safety and fleet-management features.
With two high-capacity FORGE XC8.0 batteries, a Rapid Charger, multiple guards, an anti-vibration handle, and the grinder itself, this kit provides a comprehensive cordless solution for demanding metalworking and construction applications.
