Designed for demanding deep-hole drilling (3×D, 5×D, and 8×D), DurableMills coolant-through carbide drills deliver high-pressure fluid directly to the cutting zone. This ensures instant thermal dissipation, lubricates cutting lips, and rapidly flushes chips out of deep holes, preventing chip packing and tool breakage in sticky materials like stainless steel, Inconel, and titanium alloys.
