BOA Diamond Glass Drill Bit

The BOA 34008 is an 8mm diamond tip drill bit, ideally suited for drilling holes for common plumbing fixtures, electrical fittings, and standard bathroom accessories through glass and ceramic surfaces. This practical size is frequently specified for kitchen and bathroom installations. Featuring a vacuum brazed diamond tip with welded construction, this 8mm bit represents 10 years of development expertise, delivering greater strength and endurance in demanding hard material applications. The quick-change design enables rapid bit changes, particularly valuable for professional installers working on projects requiring multiple hole sizes. Manufactured in the UK, these drills perform beyond expectation, especially when paired with the BOA CCV (Cool Clear Vision) guide and water cooling device. This combination stands out from the competition by providing superior cooling performance and clear visibility of the drilling point.
