8*20*8*60 TiSiN Coated 4 Flute Carbide Square End Mill for Carbon Steel Alloy Steel Cast Iron 8mm Cut Diameter

8*20*8*60 TiSiN Coated 4 Flute Carbide Square End Mill for Carbon Steel Alloy Steel Cast Iron 8mm Cut Diameter

Specifications:

• Cutting Diameter: 8mm
• Flute Length: 20mm
• Shank Diameter: 8mm
• Overall Length: 60mm
• Flutes: 4
• Geometry: Square End (Flat End)

Features:

✅ 8mm Cutting Diameter

• Suitable for heavy-duty milling, slotting, and profiling in large workpieces.

✅ 4-Flute Design

• Provides a balance between high feed rates and excellent surface finishes.
• Increases tool rigidity and reduces deflection under load.

✅ Square End Geometry

• Creates sharp 90° corners and flat-bottom cuts, ideal for pocketing and side milling.
• Versatile for both roughing and finishing passes.

✅ TiSiN Coating

• Excellent tool life and heat resistance for moderate-hardness materials
• Efficient chip control and higher feed‐rate capacity
• Versatility for a wide range of ferrous metals up to HRC 55

✅ Hardness rating

• HRC 55 – retains hardness and edge integrity for machining hardened steels, standard steel, cast iron, and 304/316 stainless

✅ Optimal materials:

• Carbon & alloy steel,cast iron, copper, mold steel, stainless steels

Usage:

• Face and shoulder milling for clean, flat surfaces
• Pocketing and profiling at high speeds
• General‑purpose machining of steels, cast irons, mold steels, stainless, and copper alloys
• Capable of medium-duty to heavy machining in hardened steels (≤ HRC 55)

Packaging and Shipping:

• Packaging:Typically packaged in plastic pipes or boxes to ensure protection during transit.

• Minimum Order Quantity:Varies by supplier,but generally starts from 10 pieces.

• Delivery Time:Usually within 3-5 days for standard sizes after order confirmation.

Notes:

• Before using the carbide end mill,it is recommended to measure the tool deflection and correct it if the accuracy exceeds 0.01mm.

• The tool's performance can be optimized by adjusting cutting parameters such as speed,feed rate,and cutting depth based on the material being machined.
