Description
Product Overview
This carbide corner radius end mill is designed for dynamic milling,
roughing, side milling, pocket machining, shoulder machining and
controlled contour semi-finishing of titanium alloy components.
The reinforced corner radius improves cutting-edge strength compared
with a sharp square corner while retaining a flat-bottom cutting
profile. An ultra-fine carbide substrate, HSR118 coating,
arc-formed U-shaped flute, 43° helix and chip-breaker design
help control cutting loads, chip evacuation and titanium adhesion.
Recommended Machining Applications
The combination of a flat-bottom cutting profile and reinforced
corner radius supports titanium alloy operations requiring
material-removal efficiency, edge strength and controlled
corner transitions.
Dynamic Milling
Suitable for high-efficiency toolpaths using controlled
radial engagement and consistent cutting loads.
Titanium Roughing
The U-shaped flute and chip-breaker groove provide
additional chip capacity for efficient material removal.
Pocket and Shoulder Machining
Supports flat-bottom pockets and shoulders with a
controlled radius between the wall and bottom surface.
Contour Semi-Finishing
Suitable for controlled stock removal along titanium
profiles, transitions and complex component outlines.
Designed for Titanium Alloy Machining Challenges
Titanium alloys generate concentrated cutting heat, strong
material adhesion and high cutting loads. The coating, flute
profile and reinforced radius are designed to maintain stable
cutting and reduce premature edge failure.
Chip and Heat Control
- U-shaped flute provides increased chip capacity
- Chip-breaker groove controls chip formation
- 43° helix supports smoother chip movement
- 8° positive rake reduces cutting resistance
- Efficient evacuation helps remove cutting heat
- Suitable for dynamic milling and roughing
Corner Strength and Stability
- Reinforced radius reduces tip stress concentration
- HSR118 coating helps reduce titanium adhesion
- 87°/93° unequal geometry helps suppress vibration
- 12% cobalt supports substrate toughness
- Precision radius improves profile consistency
- Rigid toolholding and low runout are recommended
Corner Radius Geometry and Cutting Performance
The carbide substrate, HSR118 coating, arc-formed flute,
reinforced corner radius and controlled edge preparation
work together to support stable titanium alloy machining.
Ultra-Fine Carbide Substrate
Ultra-fine carbide powder 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 carbide
toughness, cutting-edge strength and impact resistance
under demanding titanium cutting loads.
HSR118 High-Temperature Coating
The HSR118 coating provides high hot hardness and
stable wear resistance at operating temperatures
up to approximately 1200°C.
Anti-Adhesion Surface Performance
The coating is designed to reduce material affinity
with titanium, helping limit adhesion, built-up edge
and unstable cutting at elevated temperatures.
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.
Arc-Formed Flute Design
The arc-shaped flute helps distribute cutting loads
and supports stable chip flow during high-load
titanium alloy machining.
U-Shaped Flute Profile
The U-shaped flute provides increased chip capacity
and supports efficient evacuation during roughing,
pocket machining and dynamic milling.
8° Positive Rake Angle
The positive rake geometry supports cleaner cutting
and helps reduce cutting resistance, rubbing and
localized heat generation.
43° Helix Geometry
The 43° helix supports smooth engagement, stable
chip movement and controlled cutting forces during
dynamic and contour machining.
87° / 93° Unequal Cutting Geometry
The unequal cutting division interrupts repeated
cutting forces, helping suppress vibration and
improve stability under high-load conditions.
Chip-Breaker Groove Design
The chip-breaker groove helps control chip formation,
reduce cutting force and improve titanium roughing
and dynamic-milling efficiency.
Corner Radius Accuracy Within 3 μm
Precision grinding and profile inspection help control
the corner radius within 3 μm for repeatable pocket,
shoulder and contour machining.
Fluid-Blasting Edge Preparation
Fluid blasting helps reduce 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 value controlled within ±3 μm.
Walter Five-Axis Grinding
Walter five-axis precision grinding supports
cutting-edge sharpness, corner-radius accuracy
and repeatable tool geometry.
HELICHECK PLUS Profile Measurement
Walter HELICHECK PLUS profile measurement supports
accurate inspection of the corner radius, tool
dimensions and cutting geometry.
150× and 300× Inspection
150× optical inspection and 300× high-definition
appearance inspection help verify cutting edges,
coating condition and surface quality.
