GHDS
GHDS dual-spiral inner-cooling shallow hole drill
Product Characteristics
Dual-spiral inner-cooling structure technology-more proper structure and smooth chip removal; optimized inner and outer blade structure design-inner and outer blade has more balanced stress and stable machining; outgoing water of inner-cooling hole sprays front cutter face directly-more sufficient cooling, higher supporting strength of outer cutter holder; advanced surface treatment mode-eliminate drill surface stress, featuring green and environmental protection.
