Adjustable Suction Cup Drill Positioner

A purpose-built mechanical aid for accurate hole placement on non-porous architectural surfaces. Constructed from steel-reinforced industrial plastic, it supports drill bit diameters from 4 mm to 83 mm and delivers stable positioning via dual natural rubber suction cups. Dimensions conform to ergonomic handling norms, with tolerance allowances of ±1–3 cm per standard UK measurement practice. Alignment is achieved through a calibrated sliding shaft, engraved reference lines, and a positive-lock handle mechanism. Designed for real-world conditions: works reliably in ambient temperatures typical of UK homes and job sites, requires no maintenance beyond occasional cup cleaning, and functions equally well on newly laid tiles or decades-old marble — provided surfaces are clean, dry, and flat.
