Description
Product Overview
This carbide square end mill is designed for dynamic milling,
roughing, side milling, shoulder machining and controlled
semi-finishing of stainless steel components.
It combines an ultra-fine carbide substrate, 12% cobalt content,
Balzers AP AlCrN coating, 52%/70% dual-core geometry, an 8°
positive rake angle, a 45° helix and 88°/92° unequal end teeth
to improve chip evacuation, reduce vibration and support stable
stainless steel machining.
Recommended Machining Applications
The square cutting profile, dual-core design and unequal end-tooth
geometry support stainless steel operations requiring chip space,
cutter rigidity and stable cutting engagement.
Dynamic Milling
Suitable for high-efficiency toolpaths using controlled
radial engagement and consistent cutting loads.
Roughing
The front small-core section provides additional flute
space for chip evacuation and heat removal during
stainless steel material removal.
Side Milling
Designed for stainless steel walls, straight profiles
and peripheral surfaces requiring stable engagement.
Shoulder Machining
Supports controlled wall and flat-bottom machining of
shoulders, pockets and stepped features.
Designed for Stainless Steel Machining Challenges
Stainless steel can generate ductile chips, concentrated cutting
heat, work hardening and built-up edge. The tool geometry is designed
to maintain a cleaner and more stable cutting action.
Chip and Heat Control
- 52% front core increases available flute space
- 45° helix supports smoother chip flow
- 8° positive rake reduces cutting resistance
- Chips help carry heat away from the cutting zone
- Reduced chip recutting during dynamic milling
- Suitable for controlled roughing operations
Stability and Edge Support
- 70% secondary core improves cutter rigidity
- 88°/92° unequal teeth suppress repeated vibration
- AlCrN coating supports heat and oxidation resistance
- Controlled edge preparation improves consistency
- Stable geometry supports repeatable batch machining
- Short and rigid toolholding is recommended
Square End Mill Geometry and Cutting Performance
The carbide substrate, coating, dual-core geometry, unequal
end teeth and controlled edge preparation work together to
improve chip evacuation and stainless steel cutting stability.
Ultra-Fine Carbide Substrate
Ultra-fine carbide with a grain size below 0.6 μm
supports cutting-edge strength, wear resistance
and consistent tool geometry.
12% Cobalt Content
A 12% cobalt content provides a balance of substrate
toughness, cutting-edge strength and impact resistance
during demanding milling operations.
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 provide
increased flute space, while the secondary section
increases to approximately 70% for improved rigidity.
8° Positive Rake Angle
The positive rake geometry supports cleaner cutting
and helps reduce rubbing, cutting resistance, work
hardening and built-up edge formation.
45° Helix Geometry
The 45° helix supports smooth engagement, controlled
cutting loads and stable chip flow during roughing,
side milling and dynamic machining.
88° / 92° Unequal End Teeth
The unequal end-tooth division interrupts repeated
cutting forces, helping suppress vibration and improve
stability during roughing and dynamic milling.
Flat-Bottom Cutting Profile
The square-end geometry supports slots, pocket bottoms,
shoulders and planar features requiring a flat
cutting profile.
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, dimensional 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.
