BOA Diamond Glass Drill Bit 20mm

The BOA 340020 is a 20mm diamond tip drill bit, designed for large-diameter drilling applications through glass, tile, and other hard materials. This substantial size is ideal for waste pipe penetrations, large plumbing installations, extractor fan ducting, and heavy-duty fixtures requiring significant clearance. This drill bit features a vacuum brazed diamond tip with welded construction, the result of 10 years of development focused on delivering greater strength and endurance in demanding applications. The quick-change design enables efficient bit swapping, particularly valuable when working on installations requiring multiple hole sizes. Manufactured in the UK, these drills perform beyond expectation on challenging projects. When used with the addition of the BOA CCV (Cool Clear Vision) guide and water cooling device, this product stands out from the competition by providing superior temperature control and clear visibility, essential for accurate large-diameter drilling.
