3M 7000045662 Square Cross Pad Mandrel 1/4-20

Product Description

The 3M 7000045662 is a pad mandrel designed to securely hold Square Pads and Cross Pads that feature 1/4-20 internal threaded inserts. The mandrel shank measures 1/4 inch in diameter and is machined with a 1/4-20 external thread, providing a firm, stable connection between the pad and the drive tool. This type of mandrel is a standard accessory used in surface preparation, blending, and finishing work across fabrication, automotive, and maintenance trades. Installers and technicians rely on a properly matched mandrel to prevent pad slippage and ensure consistent contact pressure during use.

This mandrel is suited for use with compatible 3M Square Pads and Cross Pads in applications requiring controlled surface finishing, rust removal, paint blending, or weld cleanup. It fits standard rotary tools and right-angle grinders or die grinders that accept a 1/4-20 threaded accessory. Typical use environments include metal fabrication shops, auto body repair, HVAC equipment maintenance, and general industrial service work where pad-based abrasive finishing is required.

Key Features

• 1/4-20 external threaded shank mates directly with Square Pads and Cross Pads using 1/4-20 internal threaded inserts
• 1/4 inch shank diameter fits common rotary tool and die grinder collets
• Secure thread engagement minimizes pad movement during operation
• Sold individually, allowing single-unit replacement or addition to existing tool setups

Compatibility

Installation Notes

Thread the mandrel into the pad insert by hand until snug before mounting the shank into the tool collet. Ensure the tool is powered off and unplugged or the air supply is disconnected before changing or securing the pad and mandrel assembly. Follow the tool manufacturer torque guidance for collet tightening. Inspect the threaded shank and insert for wear or damage before each use.
