The Beorol Multi-Function Hole Saw Holder is a positioning and guide jig that helps you drill clean, precise holes with a hole saw in hard materials like tiles, marble, granite, ceramic, and glass. It features an adjustable opening from 20 mm to 83 mm, so you can use it with a wide range of hole saw sizes without changing jigs. The tool’s natural rubber vacuum suction base grips smoothly to flat surfaces and keeps it stable while you drill. Its durable plastic body resists cracking and withstands repeated use on tough surfaces. By holding your drill steady and centered, this multi-function holder improves accuracy and safety when cutting holes with diamond or standard hole saw bits.
