2 & 4-Flute Carbide End Mill for Steel | 1.1–25mm | BB Tool

Suitable for Processing Methods

Flat Machining/Side Processing/Spot Facer Machining/Slot Cutting Processing/U-Groove
Processing etc.
Suitable for Processing Materials
Very Suitable/Fit/Not Recommend

Multiple Cutting Edges Available

2-flute end mills are typically used for simpler milling tasks such as light planar milling and groove machining. Due to their fewer cutting edges, they are suitable for small-scale roughing and the machining of less complex workpieces.

4-flute end mills, with their four cutting edges, can provide higher cutting efficiency and stability, making them suitable for a wider range of milling tasks. They can be used not only for planar milling but also for groove machining, step surface machining, and contour milling of complex shapes. Additionally, 4-flute end mills can be used for keyway machining; although they are not specialized keyway mills, they can suffice in simpler scenarios.

Solid Cemented carbide

Utilizing micro-grain carbide substrate, it possesses enhanced wear resistance and strength, specifically designed for high-hardness high-speed cutting applications.
Increase Lifespan：2-3 Times

TIAIN Anticopper High-Strength Coating

Durable Coating/Nano Coating/Solid Carbide
The nanocoating features high hardness and exceptional wear resistance, offering superior durability compared to non-coated surfaces. With a coating hardness of approximately 4000HV, it boasts enhanced resistance to high temperatures, quadrupling to quintupling the tool’s service life.

Full-Ground Helical Groove Smooth Chip Removal

Precision ground helical flutes prevent chip adhesion; large chip capacity for smooth cutting, significantly improving production efficiency.

Large Core Diameter Design

Ensure large core diameter design under conditions that guarantee cutting space, significantly enhancing the rigidity and shock resistance of the tool to reduce breakage.

Universal Round Shank Design

The handle has a chamfered design, making it easier to clamp

Suggestions

01.Before using the tool, please measure the tool deviation. If the tool deviation accuracy exceeds 0.01mm, please correct it before cutting
02.The shorter the length of the tool extending out of the chuck, the better. If the tool extends out longer, it is necessary to reduce the speed, feed rate, or cutting amount
03.If abnormal vibration or sound occurs during re cutting, please reduce the speed and cutting amount until the situation improves
04.Steel cooling, preferably of spray type and puff type, can improve the use effect of milling cutter
05.Note: Not suitable for low-speed machines such as bench drills, electric drills, etc
