Outside Diameter
The overall diameter of the brush. For maximum efficiency and the lowest total operating cost, always select the largest practical brush diameter. Radial brushes fitted to portable power tools should not exceed six inches in diameter.
中文：刷子的整体外径。为实现最高使用效率与最低综合使用成本，请在工况允许范围内选用最大合适直径的刷子。配套手持电动工具使用的径向轮刷，直径请勿超过 6 英寸。
Trim Length
The length of fill material extending beyond the brush back or flange. A short trim length creates a stiff, aggressive cutting brush. A long trim length offers flexibility for brushing irregular surfaces and delivers a softer finishing action.
中文：刷丝伸出刷盘底座或法兰的长度。短出丝：刚性强、切削能力强；长出丝：柔韧性佳，适合异形曲面打磨，打磨效果更柔和。
Arbor Hole
The inner diameter of the mounting bore on the brush. A wide range of standard arbor holes and adapter sleeves are available to fit spindle sizes for various power drives.
中文：刷子中心安装孔的内径。我们提供多种标准轴孔与转接套筒，适配各类动力设备的主轴规格。
Operating Face Width
The contact width of the brush face during operation. Wide‑face brushes cover a larger working area and are generally stiffer than narrow‑face brushes. Narrow‑face brushes are used individually for confined spaces. Multiple brushes may also be stacked together to achieve a wider working width and eliminate streaking.
中文：刷子工作时的有效接触宽度。宽面刷覆盖面积更大，刚性通常优于窄面刷；窄面刷适合狭小空间作业；多支刷子可并排组合使用，拓宽作业幅宽，消除打磨条纹。
Brush Length
This term refers to the fill length of end brushes and tube brushes.
中文：该术语用于笔型刷与管道刷，代表刷丝部分的总长度。
