MZG Taper End Mill & Reamer System
Taper End Mills are a type of milling cutter characterized by their tapered cutting edges, which gradually narrow along the axial direction. They are primarily used for machining tapered holes, inclined surfaces, or draft angles in molds. Reamers are multi-fluted cutting tools primarily used for the precision finishing of holes to improve dimensional accuracy and surface finish.

Precision Tapered Geometry
Tapered cutting edges that gradually narrow along the axial direction, designed for machining tapered holes, inclined surfaces, and draft angles in molds with exceptional accuracy.
Advanced Coating Technology
Premium tungsten steel construction with advanced coating options providing enhanced wear resistance, thermal protection, and extended tool life for steel machining applications.
Versatile Design Options
Comprehensive range including 2-edge, 4-edge, ball head tapers, and precision reamers to meet diverse machining requirements from complex contouring to high-precision hole finishing.
System Performance Analysis
Taper End Mill Performance
The 2 Edge Tungsten Steel Coated Tapers End Milling Cutter features 2 edges made of tungsten steel with coating, designed for milling steel with hardness below HRC45°. Available with taper angles from 0.5° to 10°, these cutters are primarily used for machining tapered holes and inclined surfaces in various steel components.
The 4 Edge Tungsten Steel Coated Tapers End Milling Cutter features 4 edges for improved stability and surface finish, optimized for milling steel with hardness below HRC55°. The higher number of flutes provides superior surface finish and enhanced machining stability in demanding applications.
Our 2 Edge Tungsten Steel Coated Ball Head Tapers End Milling Cutter combines a ball nose with a tapered body, featuring ball radius from R0.5 to R5. This tool is particularly useful for complex 3D contouring and mold cavity machining, providing smooth, rounded transitions and precise geometric features.
Reamer Precision Technology
The 55° Straight-Edged Tungsten Steel Reamer provides general-purpose high-precision finishing of through-holes with 4-6 teeth configuration. Available in both coated and uncoated versions, with specialized aluminum variants for non-ferrous materials.
The 55° Spiral-Edged Tungsten Steel Reamer features spiral-shaped cutting edges ideal for finishing blind holes and interrupted cuts. The spiral design aids in chip evacuation and provides smoother cutting action, reducing chatter and improving hole straightness.
