It features micron-graded aluminum oxide abrasive bonded to a durable polyester film backing. This combination delivers a fast cut rate and a consistent, repeatable finish. The disc measures 1-3\/8 inches in diameter with a scalloped edge profile. It is suited for finishing wood, solid surface composites, plastic, fiberglass, metal, primer, e-coat, paint prep, and corrosion removal applications. Licensed tradespeople and finishing professionals use this disc in multi-step surface refinishing workflows.\u003c\/p\u003e\u003cp\u003eThis disc is designed for use in detail sanding and microfinishing applications where close tolerances and uniform scratch patterns are required. The 1-3\/8 inch diameter makes it well suited for small-surface or contoured workpiece finishing. It is commonly used in automotive refinishing, woodworking, and industrial surface prep environments. The Hookita hook and loop attachment system allows rapid disc changes between grits during multi-step finishing sequences, reducing downtime between passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicron-graded aluminum oxide abrasive provides fast cut rate and long service life across multiple substrate types\u003c\/li\u003e\n\u003cli\u003eDurable polyester film backing supports close-tolerance finishing and a consistent scratch pattern\u003c\/li\u003e\n\u003cli\u003eHookita hook and loop system enables quick attachment and removal for efficient multi-step finishing\u003c\/li\u003e\n\u003cli\u003eLoad-resistant coating helps prevent dust and debris from clogging the abrasive surface\u003c\/li\u003e\n\u003cli\u003eScalloped disc edge promotes flexibility and conformability on contoured surfaces\u003c\/li\u003e\n\u003cli\u003eCompatible with both open coat and dust control configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Hookita-compatible hook and loop backup pads and tools that accept 1-3\/8 inch diameter discs.
