Industrial reliability: The body is made from a shock-resistant alloy that provides wear resistance, deformation resistance, and unchanging dimensional stability for durable performance in practical applications. Multi-size compatibility: Adapts to a range of tile hole diameters, ensuring precise alignment and enabling a smooth exchange process that improves overall workflow continuity. Waterproof design: Reinforced seal for secure hold and impact resistance. Vacuum adsorption technology maintains reliable operation in diverse environments. Reliable positioning: Advanced calibration scale enables dependable placement of tile holes, supporting measurement-assisted alignment while preserving vertical centering accuracy to eliminate drilling deviations. Use scenarios - New tile installations in bathrooms or kitchens requiring exact hole placement for anchors and fixtures. - Renovation projects with varying tile hole sizes needing quick, accurate hole transfer and tool changes. - Professional tiling on floors or walls in commercial settings where consistent hole placement reduces errors and improves productivity.
