Know Before You Order

Some orders ship faster than others

We stock tens of thousands of parts in our warehouse, and most in-stock orders ship within 24 business hours. Because we specialize in hard-to-find tool parts, some items are sourced directly from the manufacturer after your order is placed and may require 10–14 business days before shipment. We believe in being transparent about timelines so you know what to expect before ordering. If timing is critical, please contact with your part number for an estimated delivery timeframe.

Why does M&M Tool Parts offer parts other companies don’t?

As a family-owned business, we’ve built long-standing relationships with trusted manufacturers across the industry. These partnerships allow us to source specialty parts that are often unavailable through larger retailers or online marketplaces. In many cases, M&M Tool Parts provides one of the few reliable ways to obtain these components — and we work hard to get them to you as quickly as possible.

What should I expect after placing my order?

Our team begins processing orders immediately. If your item is stocked locally, you’ll typically receive tracking information within 24 business hours. For manufacturer-sourced items, we coordinate directly with vendors to secure and ship your order as efficiently as possible. We understand downtime is frustrating, and we sincerely appreciate your patience while we help source parts that can often be difficult to find elsewhere.

31-92-0257 PADDLE TRIGGER ASSEMBLY KIT (Milwaukee Authentic Spare Part)
Read More

The Milwaukee 31-92-0257 Paddle Trigger Assembly Kit is a genuine OEM replacement trigger component for the Milwaukee 2882-20 M18 FUEL 4-1/2" / 5" Grinder with Paddle Switch. The paddle is the external user-operated component used to actuate the grinder's switch mechanism during operation.

Product Specifications

Part Number: 31-92-0257
Part Type: Paddle Trigger Assembly Kit
Manufacturer: Milwaukee Tool
Application: M18 FUEL Angle Grinder
Switch Configuration: Paddle Switch
Condition: Genuine OEM Milwaukee Replacement Part

Tool Compatibility

The Milwaukee 31-92-0257 Paddle Trigger Assembly Kit is designed for:

Milwaukee 2882-20 – M18 FUEL 4-1/2" / 5" Grinder with Paddle Switch

Verify the complete catalog and serial information on your grinder against the applicable Milwaukee service parts documentation before ordering. Milwaukee produces several similar M18 FUEL grinders with different switch and trigger configurations.

Part Function

The paddle trigger provides the external control surface used by the operator to actuate the grinder's switch mechanism. Pressing the paddle operates the associated internal switching components, while releasing it allows the paddle mechanism to return to its normal position.

When to Replace the Paddle Trigger

Replacement may be appropriate if the original paddle is cracked, broken, physically damaged, binding, or can no longer properly actuate the switch mechanism.

If the grinder does not start or operates intermittently while the paddle itself moves normally, the problem may involve the electrical switch, wiring, electronics, battery, or another internal component. The trigger assembly should be inspected before replacement rather than assuming it is the cause of an electrical operating problem.

Important Compatibility Information

Part number 31-92-0257 is intended for the applicable paddle-switch configuration of the 2882-20. Do not select a replacement trigger based only on grinder size or M18 FUEL branding, as similar Milwaukee grinders may use different trigger and switch assemblies.
