PCD Shank Tools

Definition:
PCD shank tools are cutting tools that feature a polycrystalline diamond (PCD) tip brazed onto a steel or carbide shank. These tools are designed for machining non-ferrous materials such as aluminum, copper, brass, and composites.​

Key Features:

• Material Composition: PCD is a synthetic material composed of fine diamond crystals bonded together under high pressure and temperature. This structure provides exceptional hardness and wear resistance.​
• Applications: Ideal for machining non-ferrous metals and composites, especially in industries like aerospace, automotive, and electronics.​
• Advantages:
• Extended Tool Life: PCD shank tools offer longer tool life compared to conventional carbide tools, reducing downtime and tool replacement costs.
• Superior Surface Finish: The hardness of PCD allows for high-precision machining, resulting in excellent surface finishes.
• High Cutting Speeds: PCD tools can withstand high cutting speeds, improving productivity.​
• Limitations:
• Not Suitable for Ferrous Materials: PCD is not effective for machining ferrous materials due to its chemical reactivity with iron.
• Brittleness: PCD tools can be brittle and may fracture under improper handling or cutting conditions.​

Types of PCD Shank Tools:

• End Mills: Used for milling operations, available in various geometries and sizes.
• Drills: Designed for drilling applications, offering high precision and wear resistance.
• Reamers: Used for finishing holes to precise dimensions and smooth finishes.
