倒角深度测量尺的结构如图1所示。可用来测量孔的倒角深度、锪孔深度、台阶孔深度。还可当深度尺使用。对于不便于用其他量具测量的小孔孔径,则可把该测量尺作为孔径塞尺、测量小孔孔径
Chamfering depth measuring ruler structure shown in Figure 1. Can be used to measure the chamfer hole depth, countersink depth, step hole depth. Can also be used as depth gauge. For inconvenient to use other measuring aperture orifice, you can use the measuring ruler as the aperture feeler, measure the aperture aperture
