Diamond Flap Disc:
A flexible grinding tool with diamond (synthetic) as abrasive, composed of multiple layers of fan-shaped abrasive cloth pieces (flaps) superimposed in a louver-like shape, with the center fixed on a metal or glass fiber backing plate.
Backing Plate:Made of metal (such as aluminum alloy) or glass fiber, it provides support and heat dissipation.
Flaps:It is made of abrasive cloth coated with a diamond coating and arranged in a radial pattern.
Available Dia.: 4" 100x16mm, 4.5"115x22mm, 5"125x22mm
Available Type:
T27(Flat): Suitable for planar grinding (contact angle 0° - 15°)
T29(Conical):Adheres to the curved surface and efficiently removes the material
Backing & Design:
Glass fiber backing: High-temperature resistant, tear-resistant, and the synchronized consumption feature can extend the product's lifespan.
Plastic backing: Lightweight, compatible with grinding machine protective covers, enhancing safety.
Grit Range:
Coarse:60-80#
Medium: 100-180
Fine:220-400#
Abrasive Types:
Diamond abrasive: Super hard and wear-resistant, suitable for processing high-hardness materials such as hard alloys and ceramics.
Aluminium oxide: Universal type, suitable for steel and cast iron (with high cost-effectiveness).
Zirconia: High durability, suitable for stainless steel and alloy steel.
Silicon carbide: High sharpness, suitable for non-metallic materials (wood, stone).
Application fields:
Stone/ceramic cutting
Installation Standard (Mounting):
Bushing: 7/8 inch (standard) or 5/8-11 thread (for angle grinder compatibility)
Key Advantages:
The lifespan of diamond abrasive materials can be more than three times that of ordinary abrasive materials.
Low vibration/noise enhances operator comfort; diamond coating extends service life.
