These water-feeding swivel adaptors are for supplying water or coolant through the centre of a 10mm shank core drill bit, such as our range of sintered diamond core drills. This will help cool the drill bit and the material you are drilling, preventing overheating and prolonging your drill bit's life. Furthermore, this will help prevent cracks from forming in your material.

Choose from either a 10mm arbor or a 12mm arbor to fit into your drilling equipment.

• The collet opens to hold a 10mm shank core or hollow drill bits
• 8mm water feed for connecting to a water hose or pipe
