GEM Industries Trizact sanding disc is an 11 inch Hookit aluminum oxide abrasive disc designed for consistent surface sanding where a 150 micron grade is needed. The Trizact construction works as a structured abrasive that helps deliver an even cut across the disc face, which supports predictable results when multiple discs are used on the same job. The 11 inch diameter creates a wide sanding path, so larger flat areas can be processed efficiently with fewer passes. The 150 micron grade defines a relatively coarse finishing step in a controlled sequence, giving installers and refinishers a repeatable way to hit the same surface profile from piece to piece. The aluminum oxide grain is specified as the cutting mineral on this disc, providing the abrasive action that removes material while supporting a uniform scratch pattern during woodworking, solid surface, or similar sanding operations.
This GEM Industries Trizact aluminum oxide disc uses a Hookit style backing, which is made to work with hook and loop style sanding pads on compatible machines. The hook attachment system lets the disc be pressed onto the pad and pulled off again without adhesives or clamps, helping keep sanding heads ready for quick disc swaps. The 11 inch size matches tools and backup pads designed around this diameter, and the no-hole face pairs with solid pads that do not route air through the disc. The 150 micron grade establishes where this disc sits in a step-sanding sequence, so it can be assigned to a defined pass in the workflow and used consistently from job to job.
The GEM Industries Trizact 11 inch Hookit aluminum oxide disc is positioned for sanding tasks that call for a broad contact area and a defined 150 micron abrasive cut. The disc belongs to the abrasive discs segment within the abrasives category, so it fits naturally into setups that already rely on disc-based sanding rather than belts or sheets. Because the disc face has no holes, it pairs well with solid backup pads where vacuum channels are not part of the system, which suits many dedicated finishing and surfacing tools. The 11 inch diameter is well suited to work on large, flat surfaces such as wide panels, countertops, or similar components, where full-width passes are preferred. Within an ordered abrasive sequence, the specified 150 micron grade helps define this disc as one stage in a multi-step process, lining up its role between coarser stock removal steps and finer finishing passes.
The Trizact designation identifies a structured abrasive approach on this GEM Industries disc, which is intended to keep the cutting points distributed in a controlled pattern for more uniform sanding. That structure works together with the aluminum oxide mineral to maintain a consistent scratch profile from the center of the 11 inch disc out toward the edge, supporting even results as the tool travels across a work surface. The Hookit backing allows the disc to be mounted and removed without adhesives, which supports frequent disc changes when moving between different micron grades in a defined sequence. The no-hole layout means the abrasive surface is continuous, which keeps the contact patch predictable when aligning the tool to edges or features. With the S-104H manufacturer part number clearly identifying this exact disc, shops can reorder the same 150 micron, 11 inch, Hookit aluminum oxide disc whenever they want to repeat a proven sanding setup on future projects.
This GEM Industries Trizact disc uses aluminum oxide as the abrasive mineral, which provides the cutting action needed for material removal and a consistent scratch pattern on compatible surfaces.
The 150 micron designation defines the abrasive size on the disc, placing it at a specific cut level so it can be assigned to a known step within a multi-stage sanding sequence.
The Hookit style backing is made for hook and loop attachment, allowing the disc to be pressed onto and removed from compatible pads quickly during sanding work.
This 11 inch abrasive disc is specified with no holes, so the full face is devoted to abrasive contact when used with solid backup pads that do not rely on through-disc airflow.
The S-104H identifier is the manufacturer part number for this 11 inch, 150 micron, Hookit aluminum oxide Trizact disc, which distinguishes it from other sizes or grades.
This product is classified by Wurth Baer Supply under abrasives and abrasive discs, placing it in the disc segment for rotary or orbital sanding equipment.
The GEM Industries Trizact 11 inch Hookit aluminum oxide abrasive disc with a 150 micron grade and no holes gives shops a defined sanding step built around a large, continuous abrasive face. The S-104H part number ties this disc to a specific combination of diameter, mineral, backing, and micron size, which helps maintain consistency when repeating proven sanding processes. For installers and fabricators building disc-based sanding systems, this disc offers a clearly defined role within the abrasives and abrasive discs category at Wurth Baer Supply. Ordering this exact Trizact Hookit aluminum oxide disc lets you align future work with the same 150 micron performance you have already dialed in.
