Clesco W-23MT Nut Lock-Type Wheel Adapter power

SKU CH-YJE7-MTWZA MPN W-23MT

A nut lock-type wheel adapter connects abrasive wheels with a 3/8-24 threaded hole to a 1/4 inch straight shank tool

  • Product typeSanders
  • Nut lock design secures abrasive wheels firmly
  • 3/8-24 threaded hole fits compatible sanders directly
  • 1/4 straight shank mounts into standard tool holders
  • 1 inch flange diameter supports wheel stability
  • 5/8 inch maximum wheel thickness accommodated

What it is

The Clesco W-23MT is a nut lock-type wheel adapter designed for sanders. It connects abrasive wheels with a 3/8 in.-24 threaded hole to tools that accept a 1/4 in. straight shank. This accessory is intended for technicians and mechanics who need to mount compatible abrasive wheels onto straight-shank power tools for surface preparation tasks.

Deciding specification

The critical fit detail is the abrasive mounting connector: a 3/8 in.-24 threaded hole paired with a 1/4 in. straight shank on the tool side. The adapter also has a 1 in. outside flange diameter and accepts a maximum wheel thickness of 5/8 in. If your wheel uses a different thread size, shank diameter or exceeds the thickness limit, this adapter will not work.

Installation and common issues

Installation requires threading the adapter onto the wheel arbor and securing it in the tool chuck or collet; the nut lock mechanism is intended to hold the wheel firmly during operation. Problems typically arise when the wheel thread does not match the 3/8 in.-24 specification, when the shank does not seat fully in a 1/4 in. straight-shank holder, or when a wheel thicker than 5/8 in. prevents the lock nut from engaging properly.

Questions about this item

How does the 3/8-24 threaded hole translate when the adapter is mounted on a sander?

The 3/8-24 thread matches standard abrasive wheel arbors so the wheel secures directly without extra bushings.

What does the 1/4-inch straight shank limit in terms of tool compatibility?

It fits any sander or grinder chuck that accepts a 1/4-inch straight shank, which is the common size for die grinders and small right-angle tools.

Will the 2 9/16-inch overall length and 1-inch flange clear the guard on a typical right-angle sander?

The compact 2 9/16-inch length and 1-inch outside flange diameter are designed to sit inside standard guards while allowing up to 5/8-inch wheel thickness.
