OVERVIEW

Premium Linear Finishing with Walter Blendex Technology

The Walter 07M324 Blendex Drum Wheel is a high-performance abrasive tool designed for industrial metal finishing applications. Engineered with Walter's proprietary Blendex non-woven material, this drum wheel excels at producing consistent, shadow-free finishes on a wide variety of metallic surfaces. It is specifically configured with a 4-1/4" diameter and a 2" width, featuring a standard 5/8" arbor (5/8-11 threaded or keyed depending on the specific mounting hub, typically keyed for linear tools) compatible with the Walter Line-Mate III and other professional linear finishing systems.

This "Fine" grit variant is essential for the latter stages of the finishing process. It effectively blends scratch patterns left by coarser abrasives, cleans surface oxidation, and prepares the metal for final polishing or leaves a desirable satin appearance. The open-web construction of the non-woven material allows for significant air circulation during operation, which dissipates heat and prevents discoloration or warping of the workpiece—a critical factor when working with heat-sensitive alloys like stainless steel and aluminum.

Industrial fabricators rely on the 07M324 for its durability and resistance to loading. Unlike traditional coated abrasives that may clog when working on softer non-ferrous metals like copper or brass, the Blendex material maintains its cutting efficiency throughout its lifespan. This drum is an integral component for MRO operations involving food processing equipment, pharmaceutical tanks, and architectural metalwork where aesthetic consistency and surface cleanliness are paramount.

Key Applications:

  • Creating uniform satin finishes on stainless steel sheets and tubes.
  • Blending weld discoloration and minor surface imperfections.
  • Refining surfaces on aluminum, brass, and copper without gouging.
  • Maintenance and restoration of architectural railings and fixtures.

FAQ

The 07M324 is designed for linear finishing tools with a 5/8" arbor, such as the Walter Line-Mate III. It may also fit other brands of burnishers that accept 4-1/4" x 2" drums with a 5/8" shaft.

This specific wheel (07M324) is 'Fine' grit. In the Blendex system, this is typically used for refining scratches from Medium grit wheels or for achieving a final satin finish.

Yes, the Blendex non-woven material is excellent for aluminum. Its open structure resists loading (clogging), which is a common issue when grinding soft metals like aluminum.

The maximum rated speed is generally 3,800 RPM. However, for the best finishing results, it is often recommended to run linear finishing drums at lower speeds (typically 1,000 - 2,000 RPM) to prevent heat buildup.

No, this is a finishing and blending tool, not a heavy stock removal tool. For removing heavy weld seams, you should start with a coated abrasive belt or flap wheel before switching to this Blendex drum for the final finish.

No, the Blendex Drum Wheel is impregnated with abrasive grain and is designed to be used dry. Polishing pastes are typically reserved for felt or cotton drums when aiming for a mirror finish.

A flap wheel (sandpaper) cuts more aggressively and removes material. This non-woven drum is for conditioning and finishing; it modifies the surface texture without significantly altering the part's dimensions.

Generally, non-woven drums can be run in either direction, but you should always check the arrow markings on the product label. Consistent direction is key for a uniform linear finish.
