 Key Features &Advantages

External Coolant Twist Drills:
    1.Effective Surface Cooling/Lubrication: Coolant directed externally over the flutes cools the drill body and workpiece surface, reduces friction, and helps flush chips away near the hole entrance.
    2.Simpler Tooling & Lower Pressure Requirement: Easier to manufacture and maintain than internal coolant drills; works effectively with standard coolant systems at lower pressures.
    3.Cost-Effective for Shallow/Medium Holes:An efficient solution for holes where extreme depth or chip evacuation isn't the primary challenge, offering good performance at a lower cost than internal coolant drills.

Internal Coolant Twist Drills:
    1.Deep Hole Capability & Heat Management: High-pressure coolant delivered directly through internal channels to the cutting edges significantly reduces heat buildup and tool wear, enabling efficient deep hole drilling.
    2.Superior Chip Evacuation:The internal coolant stream forcefully pushes chips *out* of the hole, preventing chip jamming, re-cutting, and tool breakage, especially in deep or blind holes.
    3.Improved Surface Finish & Accuracy: Effective cooling and chip removal minimize thermal deformation and vibration, leading to better hole surface finish, dimensional accuracy, and straightness.
