Long-Neck Micro Solid Carbide Square End Mill Overview
This long-neck micro solid carbide square end mill is designed for narrow ribs, recessed walls, miniature pockets and deep mold features that cannot be reached with a standard short-reach cutter. Its micro-diameter cutting section is combined with a reduced neck to provide wall clearance while keeping the cutting edge short and supported. Selected 2- and 4-flute configurations can be matched to the workpiece material, chip space and finishing requirement.
Long-Reach Micro-Milling Configuration
Long-Neck Micro Square End Mill SeriesReduced-Neck Clearance
The neck diameter is smaller than the shank to reduce interference with deep pocket walls and narrow ribs.
Short Supported Cutting Edge
Reach is provided by the neck instead of an unnecessarily long flute, supporting delicate micro cutting edges.
Precision Square End
Supports miniature slots, flat pocket floors, small shoulders and defined mold features.
Why Use a Long-Neck Micro End Mill?
Access Behind Tall Walls
Provides toolholder and shank clearance when the cutting edge must reach below the surrounding component surface.
Controlled Edge Support
Separating cutting length from neck reach helps limit unsupported flute length and chip-packing risk.
Micro Feature Accuracy
Ultra-fine-grain carbide supports sharp micro edges and consistent geometry under controlled cutting loads.
Micro Geometry & Tool Construction
Ultra-Fine-Grain Carbide
Supports accurate micro-edge grinding and dimensional stability.
2- or 4-Flute Options
Two flutes provide more chip space; four flutes provide more cutting edges and a stronger core.
Material-Matched Surface
Coated or uncoated configurations are selected according to the workpiece and edge requirement.
Rib & Deep-Cavity Applications
Narrow Ribs
Thin rib walls, mold inserts and recessed shoulders.
Deep Cavities
Small floors and walls below the surrounding surface.
Miniature Features
Detailed slots, pockets and micro-mechanical features.
Precision Finishing
Small vertical walls and flat-bottom details with light engagement.
