A coated abrasive article includes a substrate and a plurality of abrasive particles overlying the substrate, wherein at least 5% of the plurality of abrasive particles is tooth-shaped abrasive particles.

Abrasive articles and methods of forming same

A fixed abrasive article including a blend of abrasive particles having a first type of shaped abrasive particle comprising a first height (h1), a second type of shaped abrasive particle comprising a second height (h2) less than the first height, where the blend of abrasive particles includes a first content of the first type of shaped abrasive particles and a second content of the second type of shaped abrasive particle, and the first content is different as compared to the second content.

Abrasive article including shaped abrasive particles

Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Abrasive article including shaped abrasive particles comprising a particular toothed body

A coated abrasive article includes a substrate and a plurality of abrasive particles overlying the substrate, and the plurality of abrasive particles including tapered abrasive particles having a taper fraction standard deviation of at least 0.025 and not greater than 0.090.

An abrasive grain is disclosed and may include an elongated body. The body may define a length (l), a width (w), and a height (h), where the length is the longest dimension. The elongated body may have a first end face, a second end face, and a side surface extending between the first end face and the second end face. The body can include a twist along an axis body.

Abrasive particles having an elongated body comprising a twist along an axis of the body

An abrasive grain is disclosed and may include a body. The body may include a central portion and 3 radial arms extending outwardly from the central portion along the entire length of the central portion of the body. A first radial arm, a second radial arm, and a third radial arm can define a total angle of less than 180 degrees. The body may also include at least one groove extending from a base surface along a first side of the body.

Abrasive particles having complex shapes and methods of forming same

Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface. The side surface can includes a toothed portion. The toothed portion can comprise a plurality of teeth. Each one of the teeth can have the same height.

Abrasive article including shaped abrasive particles having a tooth portion on a surface

Method of making shaped abrasive particles and articles comprising forming a flange from overfilling

An abrasive article comprising a first group including a plurality of shaped abrasive particles overlying a backing, wherein the plurality of shaped abrasive particles of the first group define a first non-shadowing distribution relative to each other.

Abrasive particles having particular shapes and methods of forming such particles

The present disclosure relates generally to coated abrasive articles that include a grinding aid aggregates in a make coat, a size coat, a supersize coat, or combinations thereof, as well as methods of making coated abrasive articles.

Coated abrasives having aggregates

An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%.

A fixed abrasive article including a blend of abrasive particles having a first type of shaped abrasive particle comprising a first height (h), a second type of shaped abrasive particle comprising a second height (h) less than the first height, where the blend of abrasive particles includes a first content of the first type of shaped abrasive particles and a second content of the second type of shaped abrasive particle, and the first content is different as compared to the second content.
