Silverline Diamond Core Drill Bit, 28 x 300mm
Heavy-duty Silverline diamond core drill bit (28x300mm) for clean, dry cutting in masonry. BSP arbor compatible.
The Silverline Diamond Core Drill Bit (28 x 300mm) is designed for precision dry-cutting in masonry applications. Its heavy-duty steel body ensures durability while the diamond dust cutting segments provide clean, efficient drilling without the need for water cooling.
This drill bit is compatible with 1/2″ BSP arbors and should only be used with drills equipped with a safety clutch. For optimal performance and safety, it’s essential to disengage hammer action when using this bit, as hammer setting can damage both the bit and the workpiece.
Applications: Excellent for creating clean through-holes in brick, blockwork, and stone, making it ideal for plumbing, electrical installations, and general construction work. The diamond-embedded cutting edge provides long-lasting sharpness, reducing the need for frequent replacements.
