Description
Product Overview
This carbide corner radius end mill is designed for shoulder milling,
pocket machining, contour milling and semi-finishing of mold, die and
tool steels with workpiece hardness up to HRC60.
Its reinforced corner radius improves cutting-edge strength compared
with a sharp square corner while retaining a flat-bottom cutting profile.
Ultra-fine carbide, HIPIMS TiAlSiN coating and unequal cutting geometry
help reduce vibration and support stable machining in demanding mold steels.
Recommended Machining Applications
The flat-bottom profile and reinforced corner radius support mold
machining operations where bottom flatness, corner strength and
cutting stability are all required.
Shoulder Milling
Suitable for machining shoulders that require a flat bottom,
controlled transition radius and improved corner strength.
Pocket Machining
Designed for pocket bottoms, recessed areas and internal
mold features with reinforced corner transitions.
Contour Milling
Supports stable peripheral cutting along mold profiles,
external contours and transition surfaces.
Semi-Finishing
Suitable for semi-finishing operations requiring stable
engagement, controlled geometry and consistent stock allowance.
Corner Radius Geometry and Cutting Performance
The carbide substrate, high-temperature coating, unequal geometry
and precision radius control are combined to support stable mold
steel machining and repeatable corner profiles.
Ultra-Fine Carbide Substrate
Ultra-fine carbide with a grain size below 0.6 μm and
12% cobalt content provides a balance of cutting-edge
strength, toughness and wear resistance.
HIPIMS TiAlSiN Coating
The TiAlSiN coating uses HIPIMS deposition and an enhanced
alloying design to improve high-temperature performance,
reduce friction and support resistance to impact and crack
propagation at temperatures up to approximately 1200°C.
Reinforced Corner Radius
The corner radius reduces stress concentration at the cutting
tip and improves edge strength compared with a sharp square corner.
Radius Accuracy Within 3 μm
Precision grinding and profile inspection help control the
corner radius within 3 μm for consistent shoulder, pocket
and contour machining.
88° / 92° Unequal End Teeth
The two-degree unequal end-tooth division helps disrupt
repeated cutting forces, reduce vibration and improve
bottom-surface machining consistency.
35° / 37° Unequal Helix
Unequal peripheral helix angles help reduce harmonic vibration
during shoulder milling, pocket machining and contour operations.
0° to −5° Rake Geometry
The controlled rake-angle range reinforces the cutting edge
and supports stable machining of difficult mold and tool steels
with hardness levels up to HRC60.
Flat-Bottom Cutting Profile
The flat-bottom profile supports pocket bottoms, shoulders
and planar features while the corner radius improves tool-tip strength.
Fluid-Blasting Edge Preparation
Fluid blasting helps remove microscopic burrs and stabilize
the cutting edge, contributing to smoother cutting and
improved workpiece surface quality.
Automated Edge Polishing
Automated rubber-bonded diamond polishing helps maintain
consistent edge preparation, with the preparation value
controlled within ±0.003 mm.
