YOUCUT U Drill 3D Type

Model: SD17.5-3D-C25
Applications: Deep hole drilling (3×D to 10×D), high-speed machining of steel (P20, 4140), stainless steel (304, 316), titanium (Ti6Al4V), Inconel, and hardened materials (HRC 50+).

 

Key Features

 3D Geometry Innovation

• Asymmetric Flute Design: Reduces cutting forces by 30%, enabling higher feed rates (up to 0.4mm/rev).

• Internal Coolant Channels: Directs high-pressure coolant (up to 70 bar) to cutting edges for heat dissipation and chip evacuation.

 Ultimate Durability

• TiAlN Coated Carbide Inserts: Withstand temperatures up to 900°C, extending tool life 2x vs. uncoated drills.

• Anti-Vibration Body: Reinforced steel shank minimizes deflection in deep holes (up to 10×D).

 Smart Chip Control

• Optimized Chip Breaker: Curls chips into small fragments, preventing clogging in deep drilling.

• Universal Compatibility: Fits standard CNC drilling cycles (G83, G73) and modular tool holders.

 

Technical Specifications

• Drill Diameter: 6mm-40mm (Standard), Custom up to 50mm

• Depth-to-Diameter Ratio: Up to 10×D

• Shank Type: Straight / Weldon Flat / HSK (Optional)

• Insert Geometry: 3D Chip Breaker for Steel / High-Positive for Aluminum

• Coating Options: TiAlN (Gold) / AlCrN (Black) / Uncoated (For Non-Ferrous)

• Max RPM: 15,000 (Dependent on diameter and material)

• Certifications: ISO 9001

 

Performance Benefits

 50% Faster Cycle Time: Replace multiple tools with single-pass drilling.
 Surface Finish Ra ≤1.6μm: Ideal for precision hydraulic and pneumatic components.
 Multi-Material Mastery: From soft aluminum to HRC 60+ hardened steels.

 

Ideal Use Cases

• Automotive: Drilling cylinder head oil galleries and crankshaft holes.

• Aerospace: Deep holes in titanium landing gear components.

• Energy: Drilling Inconel heat exchanger tubes for nuclear reactors.

• Medical: Precision holes in surgical instrument stainless steel.

• Mold & Die: Cooling channel drilling in hardened H13 tool steel.

 

Safety & Maintenance

 Use Through-Spindle Coolant (TSC): Ensure chip evacuation in holes deeper than 5×D.
 Avoid Interrupted Cuts: Maintain continuous feed to prevent insert chipping.
 Clean with Non-Chlorinated Solvents: Protect coating integrity.

 

Packaging & Support

• Professional Kit: Drill body + 5 inserts + torque wrench + insert key.

• Bulk Orders: 10 drills/box with foam inserts.

• Warranty: 12-month performance guarantee (Excludes abrasive materials).

• Free Resources: Drilling Parameter Calculator + CAM Compatibility Guide.
