Mirka MIR-40-663-150 Coarse Cut 2-3/4 in x 16-1/2 in Grip File Sheet P150

The Mirka Coarse Cut 40-663-150 is a 2-3/4 in. x 16-1/2 in. hook-and-loop (grip) file sheet in P150 grit, engineered for aggressive, durable sanding across a wide range of demanding applications. Featuring aluminum oxide grain in a semi-open coat on a specially reinforced paper backing, this maroon-colored abrasive sheet delivers consistent, reliable material removal without premature breakdown.

Key Features:

• Aluminum oxide grain — semi-open coat construction for efficient cutting and minimal loading
• Progressive Bond™ technology — Mirka's advanced dust-binding system helps reduce clogging and extend sheet life
• Reinforced paper backing — provides superior edge wear resistance even against metal edges and rounded surfaces
• Hook & loop (grip) attachment — quick and easy attachment to compatible file boards and sanders
• Flexible construction — conforms to curved and contoured surfaces for even scratch patterns
• Maroon color / P150 grit — fine coarse-cut grit ideal for lacquer, putty, glass-reinforced polyester, and weld seam preparation
• Sold in a pack of 50 sheets

Mirka Coarse Cut grip file sheets are well suited for body shop, marine, and industrial finishing work, including sanding lacquer, putty, fiberglass, and welding seams. The combination of reinforced backing and Progressive Bond™ technology means edges hold up longer than competing products, reducing the risk of deep, uneven scratch patterns caused by torn abrasive edges.
