直接答案 Quick Answer
Y5是手持式气动凿岩机，YT23、YT24、YT27、YT28、YT29A和YT29B属于气腿式产品线。两类产品的结构、配套和工况边界不同，Y5不能直接按YT系列的气腿配置选购。 Y5 is handheld pneumatic; YT23, YT24, YT27, YT28, YT29A and YT29B are air-leg models. Structures, accessories and application limits differ. Do not select Y5 using YT air-leg configurations.
什么时候把Y5列为候选 When to consider Y5
本站现有资料把Y5用于石材、采石和轻型钻孔的初步选型；具体是否适用仍需确认石材、孔径、孔深、作业方向和工作节奏。 Current documentation positions Y5 for stone work, quarrying and light drilling. Confirm material, hole diameter/depth, direction and work cycle for actual suitability.
选择前要确认什么 What to confirm before choosing
Y5不配气腿，但仍需核对气动条件、钎具、接口和最终随货配置。 Y5 does not use an air leg, but pneumatic supply, tooling, interfaces and the final included equipment must still be checked.
- 手持式还是气腿式需求 Handheld or air-leg requirement
- 石材或岩石条件 Stone or rock conditions
- 目标孔径与孔深 Target hole diameter and depth
- 供气、钎具和接口 Air supply, tooling and interfaces
- 最终配置与备件需求 Final configuration and spare parts
