Abrasive flap disc Rockforce RF-FD636Q 150x22.2 mm P36 for angle grinders

Abrasive flap disc Rockforce RF-FD636Q 150x22.2 mm P36 is a lamellar grinding wheel designed for use with angle grinders. The 150 mm diameter and 22.2 mm bore provide stable mounting on standard grinders, while the coarse P36 grit offers aggressive material removal on steel and other common metals. The flap design ensures even wear of the abrasive surface and a balance between stock removal and surface blending, making it suitable for shop and repair environments where weld finishing, deburring and edge shaping are required.

Advantages

The flap construction distributes cutting forces across multiple overlapping abrasive flaps, which results in a more uniform finish and extended usable life compared with single-layer discs. Coarse P36 grit enables fast material removal while maintaining control, and the 150 mm size gives a compromise between reach and power. The secure 22.2 mm bore fit reduces wobble and ensures consistent contact with the workpiece for predictable results.

Suitable for

• Grinding and rough stock removal on steel and ferrous metals
• Blending and finishing weld seams
• Deburring sharp edges and removing burrs
• Shaping and smoothing metal edges prior to further processing
• General workshop and repair tasks using angle grinders

Key specifications

• Disc type: lamellar (flap) abrasive disc
• Diameter: 150 mm
• Bore/hole diameter: 22.2 mm
• Abrasion grit: P36 (coarse)
• Intended material: steel and common metals

How to use

Mount the flap disc on a compatible angle grinder with a 22.2 mm arbor and ensure the disc is securely fastened according to the grinder manufacturer’s instructions. Operate the grinder at the tool’s rated speed and apply steady, even pressure; allow the abrasive flaps to do the cutting rather than forcing the disc through the material. Move the grinder across the workpiece in controlled passes to achieve consistent material removal and avoid concentrating on one spot for extended periods to reduce overheating and premature wear.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves, and hearing protection. Select P36 grit for aggressive removal; switch to finer grits for finishing passes. Inspect the disc before each use for damage or excessive wear and replace when performance declines or safety is compromised.
