Glass & Tile Hole Drill Guide — Precision suction guide for drilling clean holes in smooth surfaces Key benefits Hold drill position and angle steady: the guide secures your drill location so you can start drilling exactly where you want without slipping or re-marking. Faster, safer drilling: strong suction keeps the guide in place so you can focus on controlled drilling rather than holding a template or worrying about the bit wandering. Versatile fit for many hole sizes: one adjustable guide covers small to large openings, reducing the need for multiple guides or templates. What makes it useful Secure suction base: 4.53 inch diameter suction pad provides firm attachment to flat, smooth surfaces (glass, tile, marble, etc.), giving stability on walls or floors while you drill. Durable construction: stainless steel components combined with rubber suction materials ensure long-term reliability for repeated use. Wide adjustable range: the drill guide accommodates hole diameters from 6 mm to 83 mm (0.24 inch to 3.27 inch), making it suitable for a broad range of core bits and hole saws. Practical applications Bathroom and kitchen installations: perfect for drilling holes for faucets, shower heads, mixer fixtures, and plumbing lines through tile or marble. Glass and mirror work: position and drill precise openings for mounting hardware on mirrors, glass shelves, or shower doors. HVAC and electrical: create neat feed-throughs for ducts, venting, or electrical conduit through tiled or smooth wall surfaces. Features at a glance Function: stabilizes drill angle and position; convenient for final drilling after placement is determined Materials: stainless steel and rubber for durability and reliable suction Suction base diameter: 4.53 inches Adjustable hole range: 6 mm – 83 mm (0.24 in – 3.27 in) Compatible surfaces: glass, tiles, marble, and any smooth, flat surface How to use Clean and dry the surface, press the suction base firmly to engage, adjust the guide to the desired diameter, lock position, and drill with appropriate core bit or hole saw. This guide helps you drill more accurately and with less fuss on smooth surfaces where precision and stability matter.
