PCD Drill With Internal Cooling

Product Overview

The PCD Drill with Internal Cooling is a specialized tool engineered for high-precision drilling in AlSi7Mg cast aluminum alloy, a material widely used in automotive components. This drill combines advanced materials with innovative internal cooling technology to deliver an efficient, durable, and precise drilling solution for manufacturers.

Key Features and Benefits

Here are the drill’s core features and their associated benefits:

Internal Cooling System

Feature: Equipped with dual internal cooling holes, spaced ≤ 4.5 mm apart.

Benefits:

• Delivers coolant directly to the cutting zone, reducing machining temperatures.
• Enhances chip evacuation, preventing clogging and ensuring smooth drilling.
• Improves surface finish and maintains hole accuracy, especially in deep-hole applications.

PCD Cutting Edges

Feature: Cutting edges made from Polycrystalline Diamond (PCD), known for its exceptional hardness.

Benefits:

• Provides superior wear resistance, ideal for machining aluminum alloys with high silicon content (e.g., AlSi7Mg).
• Extends tool life significantly compared to traditional carbide tools, reducing replacement frequency.
• Maintains sharpness over extended periods, ensuring consistent hole quality.

Carbide Body

Feature: Constructed from YG6X tungsten carbide with 6% cobalt.

Benefits:

• Offers excellent rigidity and vibration damping, suitable for high-speed drilling.
• Reduces tool deflection, ensuring precise hole dimensions and roundness.
• Provides durability and wear resistance, meeting the demands of continuous, high-intensity production.

Targeted Design

Feature: Optimized specifically for AlSi7Mg cast aluminum alloy.

Benefits:

• Tailored for the moderate abrasiveness of aluminum alloys with 7% silicon content.
• Ideal for automotive component manufacturing, ensuring high precision and reliability.
• Performs consistently in deep-hole drilling, enhancing overall part quality.

Application Scenarios

The PCD Drill with Internal Cooling is particularly suited for drilling cast aluminum alloy components in the automotive industry, such as engine blocks, transmission housings, and structural parts. AlSi7Mg alloy, with its 7% silicon content, poses moderate abrasiveness, which can quickly wear down standard carbide drills. This drill, with its PCD cutting edges and internal cooling system, effectively extends tool life, reduces heat buildup, and improves chip evacuation. As a result, manufacturers can achieve higher efficiency, lower costs, and superior part quality in high-volume production environments.
