EHWA’s Rotating Drill portfolio includes PCD helical drills, burnishing drills, and thread milling drills, all designed for demanding machining tasks. The PCD helical drills combine spiral flutes with diamond-enhanced cutting edges to deliver high removal rates and longevity in abrasive or composite materials. The burnishing variants help refine surface finish following drilling, reducing tool marks and improving workpiece quality. Thread milling versions allow combining hole creation and thread generation in one operation, improving cycle time. Customized designs (face, slot, chamfer, profile) are available on demand. The drills may be built with internal coolant paths to aid cooling and chip removal during high RPM rotation. EHWA’s rotating tools are used in aerospace, automotive, composite machining, and precision part manufacturing for their durability, stability, and performance in hard or difficult materials.
