Bead blasting services
Bead blasting replaces the directional marks left by a cutting tool with an even, non-directional texture. Glass beads are driven at the part under pressure; the surface that comes back is matte or satin depending on bead size, and consistent across every face the operator can reach. Ask for the cosmetic grade where appearance is the point rather than deburring.

Example of a bead blasted part
How does a bead blasting surface finish work?
The bead size sets the result. Coarse beads cut faster and leave a grainy matte surface; fine beads leave a closer, satin sheen. Because the media strikes from every angle rather than travelling in one direction, the finish does not carry the tool path the way an as-machined surface does. It also knocks down the light burrs machining leaves at edges and hole breakouts, which is why it is often specified for function rather than looks.
