Milwaukee is releasing four new M18 FUEL grinders to join their existing line: the 4-1/2” / 5” Variable Speed Braking Grinder and the 4-1/2″-5” Flathead Braking Grinder. Both the Flathead and Variable Speed Grinders are available in paddle switch and slide switch models. These new grinders generate 11A Corded Power, provide 5 variable speed settings between 3,500 RPM and 8,500 RPM for greater control, have a low profile with a flathead design for more access to tight spaces, and feature Milwaukee’s RAPIDSTOP Brake for enhanced safety.

4-1/2″-5” Flathead Braking Grinder

The 4-1/2″-5” Flathead Braking Grinders have a low profile design to provide better access into tight spaces. The front of the tool is much narrower than other grinder models, which allows the tool to fit under ledges, in corners, and in any other tight areas that are normally hard to get to.

This grinder comes in both paddle switch and slide switch options depending on the application. Paddle switch grinders will only run when your hand is pressing the trigger. This is useful incase the tool gets dropped or you lose control of it while in use. The grinder will stop immediately when the trigger is released so the grinder does not continue to run. The RAPIDSTOP feature shuts off the tool in under 2 seconds, limiting the chance of harming you or your workpiece. On the other hand, the slide switch grinders are good for larger projects because they will stay on without having to hold down the switch. This limits fatigue for extended use when working on larger projects.

4-1/2”-5” Variable Speed Grinder

The 4-1/2″-5″ Variable Speed Grinders have 5 speed settings that range from 3,500 RPM to 8,500 RPM to complete the toughest grinding and cutting applications. The different speed levels offer more control over the tool to accommodate for cutting and grinding different materials. Both grinder models generate 11A corded power with the POWERSTATE brushless motor to offer maximum versatility and efficiency for a cordless tool. Same with the Flathead Grinders, The Variable Speed Grinder comes in Paddle Switch and Slide Switch variations and is compatible with both 4-1/2″ and 5″ cutting discs.
