M7 Air Belt Sander – Various Sizes

Get into the places a grinder can't. The M7 Air Belt Sander puts an abrasive belt on a slim, low-profile arm, making it the go-to tool for weld blending, deburring and surface finishing inside box sections, behind brackets and along tight internal corners. Available in four belt sizes, there's a configuration to suit everything from fine detail work through to heavy material removal on wider faces.

Features and Benefits

• Four Belt Sizes to Match the Job: The 10 x 330mm belt is the pick for tight-access detail and finish work, the 12.7 x 610mm adds extra reach for longer runs, the 20 x 520mm covers general-purpose fabrication duties, and the 30 x 540mm moves serious material across broader surfaces.
• High-Speed Sanding Performance: Free speeds of up to 16,000 RPM (13,000 RPM on the 30mm model) deliver fast, consistent stock removal and a clean, even finish.
• Slim-Arm Access: The narrow belt arm reaches into corners, channels and enclosed sections where angle grinders and orbital sanders simply won't fit.
• Compact and Controllable: Overall lengths from 320mm keep the tool balanced and easy to steer for precise, one-handed blending work.
• Practical Air Requirements: The 10mm and 20mm models run on just 4 CFM at 90 PSI, so they'll pair happily with a mid-size workshop compressor. The 30mm model requires 10 CFM — worth checking your compressor's free air delivery before stepping up to the big unit.
• M7 Pneumatic Build Quality: Robust construction designed for daily workshop use, backed by M7's professional air tool pedigree.

Whether you're blending welds inside a chassis rail or cleaning up fabrication work before paint, the M7 Air Belt Sander earns its place on the air line. Select your belt size above, or get in touch with the Wallace Heron team if you're not sure which configuration suits your work best.
