Why use a Zirconium Flap Disc 115MM 40 Grit 10 Discs Per Pack
|
|
|
|
1. Aggressive Material Removal (40 Grit)
|
|
|
|
40 grit is a coarse grit, perfect for heavy stock removal, weld grinding, and surface leveling.
|
|
|
|
Removes rust, paint, and burrs quickly on steel and other hard materials.
|
|
|
|
2. High-Performance Zirconium Grain
|
|
|
|
Zirconium is tougher and lasts longer than aluminum oxide.
|
|
|
|
Self-sharpening abrasive grain: as it wears, new sharp edges are exposed.
|
|
|
|
Ideal for stainless steel, mild steel, and harder alloys.
|
|
|
|
3. Durable and Long-Lasting
|
|
|
|
Flap discs wear evenly, extending disc life compared to traditional fiber or grinding discs.
|
|
|
|
You get consistent cutting performance over time.
|
|
|
|
4. Versatile 115mm (4.5") Size
|
|
|
|
Fits most standard angle grinders.
|
|
|
|
Suitable for tight spaces and detailed work while still covering enough surface area for efficiency.
|
|
|
|
5. Cooler Grinding Action
|
|
|
|
Flap design and zirconium grain reduce heat buildup.
|
|
|
|
Helps prevent metal discoloration or warping, especially on stainless steel.
|
|
|
|
6. Improved Finish Compared to Grinding Discs
|
|
|
|
Leaves a smoother surface that often requires less secondary finishing.
|
|
|
|
Good for preparing surfaces for painting, coating, or welding.
|
|
|
|
7. Cost-Effective in Packs of 10
|
|
|
|
Bulk packs provide better value for high-volume users.
|
|
|
|
Reduces downtime from frequent tool changes.

The benefits of a Zirconium Flap Disc 115MM 40 Grit 10 Discs Per Pack
|
|
|
|
1. Fast and Aggressive Material Removal
|
|
|
|
40 grit is coarse and ideal for heavy-duty grinding, weld removal, and surface leveling.
|
|
|
|
Quickly removes rust, scale, paint, and burrs.
|
|
|
|
|
|
|
|
2. High-Performance Zirconium Abrasive
|
|
|
|
Zirconium oxide is tougher and longer-lasting than standard aluminum oxide.
|
|
|
|
Self-sharpening properties mean it stays sharper longer, maintaining cutting power throughout its life.
|
|
|
|
|
|
|
|
3. Versatile 115mm (4.5") Size
|
|
|
|
Compatible with most standard angle grinders.
|
|
|
|
Great for tight spaces and precision grinding as well as general surface work.
|
|
|
|
|
|
|
|
4. Cooler Grinding, Less Heat Build-Up
|
|
|
|
Flap disc design and zirconium composition result in cooler grinding.
|
|
|
|
Reduces risk of discoloring or damaging heat-sensitive metals like stainless steel.
|
|
|
|
|
|
|
|
5. Smoother Finish
|
|
|
|
Unlike standard grinding wheels, flap discs leave a cleaner, smoother finish, often eliminating the need for additional finishing passes.
|
|
|
|
Great for prepping surfaces for paint, coatings, or welding.
|
|
|
|
|
|
|
|
6. Long-Lasting and Durable
