Solid carbide and polycrystalline diamond (PCD) micro drills ideal for precision machining in small parts Outstanding performance in small part machining up to 16 times diameter These micro drills offer outstanding performance in holes from 0.30–3.0 mm (0.012–0.118 inches) diameter. They are available in sizes that go as deep as 16 × diameter. Through-coolant in 1 mm and above diameter Internal coolant holes deliver coolant directly to the tip of the micro drill even at deep drilling depths of 16× diameter. This results in excellent cutting performance and chip evacuation. Extended tool life using PCD diamond drills The PCD diamond micro drills offer longer tool life than solid carbide. Excellent for cutting difficult materials such as platinum and green ceramics. Achievable hole tolerance: ISO standard JS7 (+/- 6 micron) 9 × D solid carbide drills have hole tolerance H7 Suitable for all materials Drill lengths: 9×,12×,16× diameter Drill diameter range: 0.3–3 mm (0.0118–0.118 inch) Use with CoroChuck 930 high precision chucks
