The curved angle of the T29 Flap Disc allows for more leverage and thus more pressure in their use which would allow the user to grind more aggressively than with the T27 Flap Disc. As you can see in this side by side comparison of a T27 flap disc and a T29 flap disc, the face of the sanding discs have a different shape. At Empire Abrasives we want to offer our customers the best products and one of those is our High Density XL Flap Discs that come in T27 and T29. These Flap Discs come in both Zirconia and Ceramic and are longer lasting than a standard flap disc.
In the bucket program we see lots of Type 27 discs used only on the edges so the recommendation is to switch to a Type 29 disc. A Type 29 flap disc is referred to as a curved disc. The Type 27 produces 20% less cuts than the Type 1 on average.
Diablo’s Steel Demon Corner-Edge flap discs feature a premium zirconium blend for up to 10X faster material removal when compared to standard grinding wheels. The flap discs’ special flap design offers flexibility and provides for a cushioned grinding effect. Diablo’s high performance flap discs combine two steps in one by simultaneously grinding and polishing.
CHOOSING ABRASIVE FLAP DENSITY. High-density flap discs contain more abrasive cloth material than standard flap discs, so they are thicker and more forgiving. Type 29: Type 29 high-density flap discs have an angled profile associated with conical flap discs. If a long lifespan is a high priority, operators may want to choose high-density flap discs over standard flap discs.
Flat has smooth grinding surface and is mainly used to grind the plane and the outside corners. The grinding surface of the curved flap disc has an upward curvature, which gives the T29 flap disc a better cutting ability in the plane. Depressed Center Cutting and Grinding Wheels Type 27 Depressed center wheels are sometimes referred to as raised hub wheels or by their shape designation Type 27.
