钎具要作为一套系统确认 Confirm tooling as one system
钎尾规格、钎杆长度、钻头直径和接口必须相互匹配，也要结合目标孔径、孔深、岩性和作业方向确认。 Shank size, steel length, bit diameter and interfaces must match each other and the target diameter/depth, rock and drilling direction.
H22等标识不等于全部信息 H22 markings are not the full specification
即使钎尾截面或基础规格相同，长度、接口、制造版本和配套要求仍可能不同，不能只看一个标识就判断通用。 Even with the same cross-section or basic marking, length, interface, manufacturing version and accessory requirements may differ.
询价时怎样写清楚 Make the inquiry specific
尽量提供现用钎具的清晰照片、完整尺寸和设备铭牌信息。 Provide clear photographs, complete dimensions and machine nameplate information for the tools currently used.
