Long-Neck End Mills Overview
This solid carbide long-neck end mill series is designed for machining deep grooves, narrow slots, recessed features and hard-to-reach surfaces where a standard-length cutter cannot provide sufficient clearance. The reduced-neck construction extends machining reach while limiting contact between the tool body and workpiece wall. Square-end, ball-nose, corner-radius and micro-diameter configurations are available with 2-flute or 4-flute geometry. Different carbide grades, coatings, cutting diameters, neck lengths and overall lengths can be selected for steel, stainless steel, mold steel, hardened steel and other application-specific materials.

Key Features and Machining Benefits
Extended Machining Reach
The long-neck construction provides clearance for deep slots, recessed walls, narrow cavities and difficult-to-access machining areas.
Reduced-Neck Clearance
A controlled neck diameter helps reduce interference between the tool body and workpiece while maintaining the required reach.
Multiple End Profiles
Square-end, ball-nose and corner-radius geometries support deep-slot milling, 3D contouring, profiling and cavity finishing.
Flexible Series Configuration
Micro diameters, extended neck lengths, different carbide grades, 2/4-flute designs and application-specific coatings are available.
Long-Neck End Mill Series
Available configurations can be selected according to the required cutting profile, machining depth, workpiece material and surface-finish requirements.
