HRC55° Square End Mills

Hiboo HRC55 carbide square end mills are solid carbide CNC cutting tools designed for machining hardened steel, alloy steel, stainless steel, aluminum and other non-ferrous metals. Available in 2-flute and 4-flute configurations, these flat end mills feature a micrograin carbide substrate and Black Nano coating for wear resistance and stable cutting performance. Standard diameters range from 1 mm to 20 mm, with custom sizes, flute configurations and geometries available for OEM and precision machining applications.

Key Features of flat end mills :

Solid Micrograin Carbide

The HRC55 square end mill uses a solid micrograin carbide substrate to provide the rigidity and wear resistance required for CNC machining. The carbide construction makes these tools suitable for applications where higher hardness and machining stability are required.

Black Nano Coating

The Black Nano coating is designed for improved tool durability and wear resistance during demanding milling operations. It is particularly suitable for applications involving harder workpiece materials.

2-Flute & 4-Flute Options

HIBOO offers HRC55 square end mills in 2-flute and 4-flute configurations, allowing buyers to select the appropriate cutting geometry according to the machining operation and workpiece requirements.

1–20 mm Diameter Range

The standard product range covers cutting diameters from 1 mm to 20 mm, making the HRC55 carbide end mill suitable for both smaller precision machining tasks and larger milling operations.

Precision Slotting & Tight-Tolerance Machining

Undersized square end mills are available for precision slot cutting and tight-tolerance fitting applications, where dimensional accuracy and clean cutting performance are important.

Square End Mill/Flat end mill Applications:

The flat-bottom geometry of a square end mill makes it suitable for producing flat surfaces, square corners, slots and shoulders.

Slot Milling

HRC55 square end mills can be used for precision slot cutting, especially where dimensional control and clean slot geometry are required.

Face Milling

The flat cutting end supports machining of flat surfaces on CNC-machined components.

Side Milling

The cutting edges can be used to machine the sides of workpieces and create defined shoulders.

Contour Milling

Square end mills are also suitable for contour machining where flat surfaces and sharp corners are required.

CNC Precision Machining

For CNC machining operations requiring a combination of tool rigidity, wear resistance and dimensional consistency, solid carbide HRC55 end mills provide a practical solution.

Flat end mill 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.

HRC55 Square End Mill FAQs

What is an HRC55 carbide square end mill?

An HRC55 carbide square end mill is a flat-bottom milling cutter designed for CNC machining applications involving high-hardness materials and other metals. The HIBOO version uses solid micrograin carbide and Black Nano coating.

What materials can an HRC55 end mill machine?

The tool can be used for high-hardness materials as well as aluminum and non-ferrous metals. HIBOO also lists aluminum, cast iron, stainless steel and hardened steel among suitable materials.

What is the difference between a square end mill and a flat end mill?

Square end mill and flat end mill generally refer to the same basic tool geometry: a flat cutting end designed to create flat surfaces, square corners, slots and shoulders.

Is the HRC55 end mill available in 2 flutes and 4 flutes?

Yes. The current HIBOO product specification offers 2-flute and 4-flute configurations.
