Strap (pipe grinding attachment) Function: Supports the mechanical rotation body, reduces the coefficient of friction during movement, and helps ensure precise rotation. Benefit: Smoother, more accurate rotation improves grinding quality and reduces wear on moving parts. Notes: Designed for use with rotating pipe-grinding setups and compatible with standard mechanical rotation bodies. Hand sander (mirror processing tool) Function: Manual sander with an integrated protective cover that prevents debris from being ejected during use. Benefit: The cover improves operator safety and keeps the work area cleaner while enabling controlled mirror-like surface finishing. Notes: Best used for detailed finishing where operator control and safety are priorities. Cordless belt sander (belt sander for metalworking) Function: Portable belt sander capable of sanding, drawing (surface texturing), polishing, and producing mirror finishes. Benefit: Cordless mobility allows on-site use and access to tight or remote work areas; versatile finishing capabilities remove the need for multiple tools. Notes: Designed for metalworking applications and for finishing surfaces to a polished or mirror quality. Belt sander (polishing attachment) Function: Tensioned belt system that uses a high-strength spring to maintain belt pressure and alignment. Benefit: High-strength spring provides sufficient strength and toughness for consistent performance, increasing durability and reducing the likelihood of damage. Notes: Suitable as a polishing attachment in production or maintenance environments. Practical applications Pipe preparation and welding: Use the strap and belt sanding attachments to remove mill scale, bevel edges, and achieve accurate rotational grinding before welding. Metal finishing and fabrication: Use the cordless belt sander and hand sander for deburring, surface texturing, and delivering polished or mirror finishes on stainless steel, aluminum, and other metal parts. Field maintenance and repair: Cordless functionality and protective hand sander cover make these tools suitable for on-site maintenance where mobility and operator safety are needed. Key attributes at a glance Functions covered: rotation support, friction reduction, debris protection, sanding, drawing, polishing, mirror finishing. Performance: Designed for accurate rotation, safe manual finishing, portable heavy-duty sanding, and durable belt tensioning with a high-strength spring. Compatibility: Intended to integrate with standard mechanical rotation bodies and common metalworking sanding setups.
