Description
3M 7100033184 is a high performance 786F Cubitron II file belt made for demanding detail grinding, deburring and spot weld removal when used with the 3M file belt sander. This 1/2" × 18" file belt uses 3M precision shaped ceramic grain bonded to an XE weight polyester backing to deliver a fast cut, cooler operation and extended service life compared with conventional abrasives. As one of file belts in the Cubitron II family, it provides consistent cut rate retention on high strength steels and hard metals with reduced loading thanks to its resin bond and grinding aid. Performance characteristics are comparable to other premium belts such as the 3M Cubitron 33440, while the 786F form factor is optimized for file belt sanders and tight access work. Use this precision ceramic file belt for rivet grinding, spot weld removal, cleaning and fast material removal in production and repair applications.
Product Features and Benefits
Precision shaped ceramic grain for fast cutting
3M Cubitron 2 precision shaped ceramic cuts faster and stays sharp longer, producing higher removal rates on hard metals while maintaining a fine finish.
XE-weight polyester backing for durability
The 3m cubitron 33440 heavy duty backing supports aggressive pressure and repeated use in the 3M file belt sander, improving belt life and dimensional stability during detail work.
Cooler cutting with resin bond and grinding aid
The 3m cubitron belts consist of resin bond plus grinding aid reduces heat build up and glazing, helping the belt remain effective longer on high strength steel and stainless applications.
Optimized form for rivets and spot-welds
Narrow 1/2" width is ideal for access to tight joints and spot welds, delivering controlled stock removal in precision cleanup operations.
Consistent performance across production runs
Designed to offer repeatable cut rates and measurable life, suitable for consistent throughput in production and maintenance workflows.
