- Flute Length: 5mm
- Shank Diameter: 4mm
- Overall Length: 50mm
- Flutes: 4
- Geometry: Square End (Flat End)
- Coating: TiSiN (Titanium Silicon Nitride) – offers strong wear resistance,
high oxidation threshold (~1,000 °C), and low friction for extended
tool life
- Carbide grade: HRC 55–rated micro-grain carbide – excellent toughness and
hardness for machining up to 55 HRC
Performance & Typical Applications:
- Finishing & precision milling: 4 flutes deliver smooth surfaces and tight corner clean-up
- Face and shoulder milling, pocketing, profiling – suitable for small features and detailed work
- High-speed CNC machining – TiSiN coating allows faster speeds with minimal wear
- Tough material operations – micro-grain carbide cuts hardened steel and cast iron reliably
Usage:
- Face and shoulder milling for clean, flat surfaces
- Pocketing and profiling at high speeds

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.
