Cumi – Hi-Life Flap Wheel 150X25X31.75 Grit 400

Cumi – Hi-Life Flap Wheel 150X25X31.75 Grit 400

The CUMI Hi-Life Flap Wheel (150 x 25 x 31.75 mm) in 400 Grit is designed for precision polishing, fine finishing, and light defect removal on stainless steel, mild steel, and metal alloys. Built on a large-diameter flange with densely packed X-weight cotton flaps coated in uniform Aluminum Oxide grains (XG 542), this wheel exposes fresh abrasive edges continuously as the flaps wear.

The ultra-fine 400 Grit rating delivers a smooth, bright finish on tubes, pipes, vessels, and contoured components without loading or gouging.

Key Features & Benefits

• Densely Packed Flaps: High flap density provides a smoother surface finish and significantly longer wheel life compared to open-packed wheels.

• Consistent Non-Loading Action: Uniformly wearing X-weight cotton flaps continually expose fresh Aluminum Oxide mineral, preventing glazing and maintaining an even finish from start to end.

• Fine 400-Grit Polishing: Ideal for pre-buffing preparation, removing fine scratch patterns, and achieving uniform satin-to-bright finishes on stainless steel.

• Low-Vibration Flange Design: Uniform adhesive distribution across the 31.75 mm flange bore ensures strong flap bonding and stable, low-vibration operation at high speeds.

• Contour Conformability: Flexible coated flaps adapt smoothly to curved profiles, pipe outer diameters (OD), and intricate fabricated parts.
