Product Description

Q&A

The HRC58 Carbide Square End Mill from Hiboo Tools is a high-performance solution specifically engineered for the precision machining of hardened steels and heat-treated alloys up to HRC58. Utilizing a premium 0.4μm ultra-micro grain tungsten steel substrate, this tool offers the perfect balance of toughness and hardness to prevent edge chipping during high-speed operations.

Enhanced with an advanced AlTiSiN coating, it provides exceptional thermal stability (up to 1100°C) and superior wear resistance, making it ideal for dry cutting in mold and die manufacturing. The 4-flute design ensures high rigidity and a flawless surface finish on materials like SKD11, D2, and H13. Whether performing side milling or finishing, our CNC milling cutters deliver the reliability and extended tool life required for demanding industrial applications.

Key Features:

Flat Bottom: This allows for the creation of flat surfaces and square corners.

Straight Cutting Edges: These edges enable the mill to cut cleanly and efficiently through the material.

Various Sizes and Coatings: Square end mills come in different diameters, lengths, and with various coatings to enhance performance and tool life, such as TiN (Titanium Nitride) or TiAlN (Titanium Aluminum Nitride).

Applications:

Face Milling: Creating a flat surface on the workpiece.

Slot Milling: Cutting slots into the material.

Side Milling: Machining the sides of a workpiece.

Contour Milling: Machining complex shapes with flat surfaces and sharp corners.

Material Considerations:

High-Speed Steel (HSS): Good for general-purpose milling.

Carbide: Offers higher cutting speeds and longer tool life, suitable for harder materials.

Cobalt: Provides better wear resistance and toughness than HSS.
