Description
Product Overview
This carbide corner radius end mill is designed for dynamic milling,
side milling, pocket machining, shoulder machining, contour milling
and controlled semi-finishing of stainless steel components.
Its reinforced corner radius improves cutting-edge strength compared
with a sharp square corner while retaining a flat-bottom cutting profile.
The ultra-fine carbide substrate, Balzers AP AlCrN coating,
52%/70% dual-core geometry and unequal cutting design help improve
chip evacuation, vibration resistance and machining stability.
Recommended Machining Applications
The combination of a flat-bottom cutting profile and reinforced
corner radius supports stainless steel machining where chip control,
bottom flatness and cutting-edge strength are all required.
Dynamic Milling
Suitable for high-efficiency toolpaths using controlled
radial engagement and stable cutting loads.
Side Milling
Designed for stainless steel walls, profiles and peripheral
surfaces requiring improved corner strength.
Pocket and Shoulder Machining
Supports flat-bottom pockets and shoulders with a controlled
corner transition between the wall and bottom surface.
Contour Semi-Finishing
Suitable for controlled stock removal along stainless steel
profiles, transitions and complex outlines.
Designed for Stainless Steel Machining Challenges
Stainless steel can generate ductile chips, concentrated cutting
heat, work hardening and built-up edge. The dual-core structure and
positive cutting geometry help maintain a cleaner and more stable cut.
Chip and Heat Control
- 52% front core provides additional flute space
- 45° helix supports smoother chip movement
- 8° positive rake reduces cutting resistance
- Efficient chip evacuation helps remove cutting heat
- Reduced chip recutting during dynamic milling
- Suitable for controlled roughing and semi-finishing
Corner Strength and Stability
- Reinforced radius reduces tip stress concentration
- 70% secondary core improves cutter rigidity
- 88°/92° unequal geometry helps suppress vibration
- AlCrN coating supports heat and wear resistance
- Precision radius improves profile consistency
- Rigid toolholding and low runout are recommended
Corner Radius Geometry and Cutting Performance
The carbide substrate, coating, dual-core geometry, reinforced
corner radius and controlled edge preparation work together to
support stable stainless steel machining.
Ultra-Fine Carbide Substrate
Ultra-fine carbide with a grain size below 0.6 μm supports
cutting-edge strength, wear resistance and consistent
corner radius geometry.
12% Cobalt Content
A 12% cobalt content provides a balance of substrate
toughness, cutting-edge strength and impact resistance
during demanding stainless steel milling.
Balzers AP AlCrN Coating
The AP AlCrN coating provides high hardness, heat resistance
and oxidation resistance at operating temperatures up to
approximately 1200°C.
52% / 70% Dual-Core Design
The front core section is approximately 52% to increase
flute space, while the secondary section increases to
approximately 70% for improved cutter rigidity.
Reinforced Corner Radius
The corner radius reduces stress concentration at the
cutting tip and improves edge strength compared with a
sharp square-end corner.
Flat-Bottom Cutting Profile
The flat-bottom geometry supports pocket bottoms,
shoulders and planar features while maintaining a
controlled corner transition.
8° Positive Rake Angle
The positive rake geometry supports cleaner cutting
and helps reduce rubbing, cutting resistance, built-up
edge and local work hardening.
45° Helix Geometry
The 45° helix supports smooth engagement, controlled chip
flow and stable cutting during dynamic milling, side milling
and contour machining.
88° / 92° Unequal Cutting Geometry
The unequal cutting division helps interrupt repeated
cutting forces, suppress vibration and improve machining
stability during roughing and dynamic milling.
Corner Radius Accuracy Within 3 μm
Precision grinding and profile inspection help control
the corner radius within 3 μm for consistent pocket,
shoulder and contour machining.
Fluid-Blasting Edge Preparation
Fluid blasting helps remove microscopic burrs and
stabilize the cutting edge, supporting smoother cutting
and improved workpiece surface quality.
Automated Edge Polishing
Automated rubber-bonded diamond polishing helps maintain
consistent preparation across all cutting edges, with
the preparation value controlled within ±0.003 mm.
Walter Five-Axis Grinding
Manufacturing using Walter five-axis precision grinding
supports cutting-edge sharpness, corner-radius accuracy
and repeatable tool geometry.
Multi-Stage Inspection
Walter HELICHECK PLUS profile measurement, 150× optical
inspection and 300× high-definition appearance inspection
support consistent batch quality.
