Diamond drill tile hole locator, adjustable 4mm - 83mm ceramic glass marble hole saw openings centering drill guide locator holder

【More stable】- Unlike traditional suction cup drill guides, our tile hole locator uses a double suction cup, which has good strength and prevents side bending or falling to keep the template firmly in place. The adjustable tile drill guide has a strong clamping force, so the drill bit doesn't move and its operation remains smooth. 【Multifunctional Hole Locator】 The adjustable plate opening length is 4 to 83 mm, large enough to accommodate hole saws of all sizes, meeting your various drilling needs and allowing for quick adapter changes. 【High Quality】 - The glass drill guide is made of engineering-grade plastic, durable, safe, not fragile, reusable, high hardness, and long-lasting, saving you money. 【Easy to Use】 - The tile drill locator can be firmly attached to reference points on smooth surfaces. The wheel axle guides the drill bit's rotation without jamming, resulting in more precise drilling, convenient for daily drilling tasks, and significantly improving work efficiency. (Note: Applies to smooth surfaces only)

【Wide Application】- The drill locator is small, easy to carry and store, perfect for drilling holes in ceramic, glass or marble tiles, aquariums, granite and ceramic surfaces.
