PRODUCT FAQ
-
What grit is the 3M Cubitron II Hookit Disc 950U?
The 40+ F-weight grit provides excellent cutting performance for general purpose sanding and grinding applications.
-
Can I use this disc on a standard 5-inch orbital sander?
Yes! The 5-inch size with Hookit attachment is designed to work with standard 5-inch orbital sanders that accept Hookit backing pads.
-
How many discs come in each carton?
Each carton contains 50 discs, and there are 250 discs total per case (5 cartons).
-
What does "No Hole" mean on this product?
"No Hole" means this disc doesn't have a center hole, making it ideal for sanding flat surfaces without obstruction from the backing pad center.
-
Is Cubitron II technology better than standard aluminum oxide?
Absolutely—Cubitron II features advanced ceramic grain technology that fractures as it wears, continuously exposing sharp edges for faster cutting, longer life, and cooler operation compared to traditional abrasives.
The 3M Cubitron II Hookit Disc 950U is engineered with 3M's Precision-Shaped Grain technology, an advanced abrasive innovation designed to progressively break down during use. As the grain fractures, it continuously exposes fresh, sharp cutting edges that maintain exceptional cutting performance across the entire lifespan of the disc. This self-sharpening characteristic enables the disc to sustain a remarkably high cut rate while simultaneously reducing the risk of substrate overheating, a critical consideration in precision finishing work. The grains are strategically arranged in an open-coat configuration, which is specifically formulated to minimize abrasive particle accumulation on the work surface—a particularly important feature when working with materials like aluminum that are prone to clogging. The combination of these design elements results in an abrasive solution that delivers superior cutting speed and extended product life compared to conventional alternatives.
Aggressive Performance Paired with Professional-Quality FinishingThe 3M Cubitron II Hookit Disc 950U represents a comprehensive engineering achievement, seamlessly integrating advanced grain technology, structural integrity, and refined surface preparation capabilities. From the composition of the abrasive grain itself to the precision-engineered backup pad attachment system, every component works synergistically to produce a sharp, forceful cutting action that simultaneously generates consistent, high-quality surface finishes. This versatile combination makes the disc particularly effective for demanding panel sanding and frame sanding applications where both productivity and finish quality are essential.
Hook-and-Loop Attachment SystemThis disc is part of 3M's comprehensive Hookit disc collection, specifically designed for work environments where traditional adhesive-backed abrasives may be compromised by dust accumulation, dirt, or debris displacement. The Hookit attachment mechanism enables quick, secure fastening to a compatible hook-and-loop backup pad (available separately) on random orbital sanders. The system allows for straightforward removal without residue, facilitating multiple reuse cycles throughout the abrasive's operational life.
