71985 DISC FLAP TYPE29 40GRIT 45IN

Description

Overview

The Forney Flap Disc, Blue Zirconia, Type 29 (71985) is designed for aggressive material removal and surface finishing on right angle grinders.

Technical Features

• Zirconia Aluminum Oxide Abrasive: A self-sharpening grain compound that continuously exposes new cutting points as flaps wear, maintaining consistent cutting performance throughout the disc’s service life.
• Multiple Layered Flap Construction: Stacked zirconia cloth flaps expose fresh abrasive surfaces during use, extending disc longevity significantly compared to standard sanding discs.
• Type 29 Depressed Center Profile: Angled disc geometry increases surface contact during aggressive stock removal and allows for improved operator control on flat and contoured workpieces.
• Reinforced Fiberglass Backing Plate: Provides structural rigidity and support under load, maintaining disc integrity at operating speeds up to 13,300 RPM.
• Automated Lamination Process: State-of-the-art automated equipment bonding ensures consistent flap adhesion and uniform abrasive distribution across the disc surface.
• 7/8 in. Arbor Fit: Standard arbor sizing ensures direct compatibility with common right angle grinder spindle configurations without adapters.

Applications

• Rough stock removal on metal surfaces where fast cutting action is required.
• Fine finishing operations on weld seams, fabricated parts, and structural steel.
• Surface preparation on flat and contoured workpieces prior to painting or coating.
• General-purpose grinding tasks requiring flexibility across both coarse removal and finishing in a single disc.
