Long neck end mills are designed for deep cavities, narrow grooves, pockets and 3D contour machining. Their extended neck provides greater reach, allowing the tool to access deep and hard-to-reach areas that standard end mills cannot easily reach.

Long neck carbide end mills are available in different geometries and tool specifications for machining mold steels, hardened steels and non-ferrous materials.

Applications

Long neck end mills are commonly used for:

• Deep cavity machining

• Deep slotting and pocketing

• 3D contour machining

• Mold and die machining

• Precision machining

• Hard-to-reach areas

Long Neck End Mill Series

BAIYANG TOOL FACTORY offers four series for different workpiece materials and machining conditions.

UU Series – Hardened Steel

Designed for semi-finishing and finishing hardened steels above HRC 55, including S136, SKD11, DC53, 440C, D2, Cr12MoV, H13, 42CrMoA and ASP30.

SS Series – Pre-Hardened & Medium-Hard Materials

Suitable for machining P20, 718H and other pre-hardened materials. It can also be used for semi-finishing and finishing HRC 48–52 materials such as NAK80, H13 and S136.

US Series – Mold Steel
