New Dolphin Multi-Purpose Oil Hole Drill
The New Dolphin Multi-Purpose Oil Hole Drill is designed for high-speed drilling
applications that demand superior heat dissipation and chip evacuation. Featuring a
140° point angle, it enables efficient penetration with reduced cutting forces, while the
30° helix angle ensures smooth chip evacuation, reducing heat buildup and improving
tool stability. Available in 3xD, 4xD and 7xD
Internal coolant channels enhance thermal management and lubricity, making this drill ideal for stainless steels, non-ferrous alloys, cast iron, and other challenging materials. The single-margin design improves hole accuracy and surface finish, ensuring consistent results in precision machining.
