It is ideal for tough detail work like cleaning, deburring, blending and finishing as well as working in small confined spaces. The 3M Cubitron II File Belt 786F is equipped with 3M Cubitron II Abrasives, which feature our Precision-Shaped Grain (PSG) technology with uniformly sized ceramic grains and precisely shaped triangular structures - essentially, sharp peaks that slice, not plow, through paint and metal. These grains are electrostatically oriented on the abrasive surface for the most efficient cut and even wear. Additionally, they fracture during use to maintain sharp abrasive edges resulting in a 30% faster cut and lasting 2x longer life than conventional ceramic abrasives. 3M Cubitron II File Belt 786F is available in various coarse grades and various widths as well as various lengths; it can be fitted on to various types of file belt machines available on the market. It helps to maximise productivity and deliver an efficient process in the workshop. Review: These wear out fast. - I want to start by saying that I am new to choosing sandpaper for different tasks. I bought this for work to clean weld spots in tough spots. I have the milwaukee m12 adjustable belt sander and these fit perfectly. However they wear out incredibly fast. This could be due to my inexperience, or the product so I still gave it 5 stars. This belt and sander combo will chew through metal at a cost.the bright color of the belt does make it nice and easy to see through the sparks flying to the ceiling. Review: There is no better - Over the past few years I find myself only using 3M Cubitron abrasives. When I do the math it saves me money and time. Paying 1.5-2.5x the price for something that cuts better, faster, and lasts 10x as long is a no-brainer. I love Cubitron in every form. ## Features - LONGER LASTING: Cubitron II delivers 30 percent faster cut and double the life of other premium abrasives - UNIFORM ABRASIVE: 3M Cubitron II technology provides an efficient cut that easily cleans, strips, and deburrs - FAST CUTTING: Versatile belt slices through hard metal for quick cut - COMPATIBLE: Grinds out rivets and spot welds quickly when used with 3M File Belt Sander - RELIABLE: Heavy-duty belt stays reliably strong for consistent performance - For industrial/occupational use only. Not for consumer sale or use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PB3OAJI | | Best Sellers Rank | #250,736 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #250 in Sander Belts | | Brand Name | 3M | | Compatible Material | Metal | | Customer Reviews | 4.4 4.4 out of 5 stars (37) | | Global Trade Identification Number | 00051131334373, 50051131334378 | | Grit Material Type | Ceramic/Aluminum Oxide Blend | | Grit Number | 36 | | Grit Type | 36+ Grit | | Included Components | 10 belts per carton | | Item Dimensions | 1.38 x 2.63 x 5.5 inches | | Item Type Name | File Belt | | Item Weight | 3.22 ounces | | Manufacturer | 3M | | Material Type | Zirconia Alumina | | UPC | 051131334373 | | Unit Count | 1.0 Count | | Warranty Description | Call vendor for warranty | ## Product Details - **Brand:** 3M - **Grit Material:** Ceramic/Aluminum Oxide Blend - **Grit Type:** 36+ Grit - **Item dimensions L x W x H:** 1.38 x 2.63 x 5.5 inches - **Material:** Zirconia Alumina ## Images ![Cubitron II File Belt, 33437, 36+ Grit, 3/8 in x 13 in, Pack of 10 File Belts, Resin Bonded, Spot Weld Removal - Image 1](https://m.media-amazon.com/images/I/61zFzz-ILWL.jpg) ## Available Options This product comes in different **Size, Grit Type** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These wear out fast. *by R***R on January 28, 2026* I want to start by saying that I am new to choosing sandpaper for different tasks.

Outlasts all the others I've tried and puts the cheap ones to shame.
