Description
Product Overview
This carbide corner radius end mill is designed for aluminum
pocket machining, shoulder milling, side milling, profile
machining and controlled contour semi-finishing of
non-ferrous components.
The reinforced corner radius improves cutting-edge strength
compared with a sharp square corner while retaining a
flat-bottom cutting profile. Imported carbide rods,
sharp positive-rake geometry, a 55% core diameter,
a 45° helix and 1200-grit precision-ground cutting edges
support smooth chip evacuation, low cutting resistance
and consistent aluminum surface quality.
Recommended Aluminum Machining Applications
The combination of a flat-bottom cutting profile and
reinforced corner radius supports aluminum operations
requiring efficient material removal, improved corner
strength and a controlled transition between the bottom
and side wall.
Pocket Machining
Suitable for aluminum pockets, recessed areas
and cavity bottoms requiring a defined internal
corner radius.
Shoulder Milling
Designed for aluminum shoulders and stepped
features requiring stronger corner geometry
than a sharp square-end tool.
Side and Profile Milling
Supports aluminum walls, external profiles
and peripheral surfaces with stable cutting
engagement.
Contour Semi-Finishing
Suitable for controlled stock removal along
component profiles, transitions and curved
aluminum features.
Designed for Aluminum Machining Challenges
Aluminum can produce long ductile chips, built-up edge,
burrs and unstable cutting at sharp tool corners.
The reinforced radius, positive rake geometry and
sufficient flute space help improve cutting stability.
Chip Evacuation and Cutting Efficiency
- Standard three-flute design balances feed capability and chip space
- 55% core diameter retains sufficient flute capacity
- 45° helix supports smooth upward chip movement
- Positive rake geometry reduces cutting resistance
- Efficient evacuation helps reduce chip recutting
- Suitable for pockets, shoulders and side milling
Corner Strength and Surface Control
- Reinforced radius reduces stress concentration
- 1200-grit grinding improves cutting-edge consistency
- Sharp geometry helps reduce burr formation
- DLC option helps reduce friction and aluminum adhesion
- Precision radius supports repeatable transitions
- Rigid toolholding and low runout are recommended
Corner Radius Geometry and Cutting Performance
The carbide substrate, reinforced corner radius,
positive rake angles, helix geometry and precision
grinding work together to support stable aluminum
pocket, shoulder and contour machining.
0.8 μm Carbide Grain Size
Imported carbide rods with an approximately
0.8 μm grain size support consistent cutting-edge
geometry, wear resistance and stable production quality.
10% Cobalt Content
The 10% cobalt content provides a balance of
carbide hardness, cutting-edge strength and
substrate toughness for aluminum and
non-ferrous machining.
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 pockets,
shoulders and planar aluminum features while
retaining a controlled wall-to-bottom radius.
Standard Three-Flute Structure
The standard three-flute configuration provides
a practical balance of cutting-edge engagement,
tool rigidity and sufficient flute space for
aluminum-chip evacuation.
55% Core Diameter
The approximately 55% core diameter balances
cutter rigidity with sufficient flute capacity
for aluminum-chip evacuation.
45° Helix Geometry
The 45° helix supports smooth cutting engagement,
stable chip movement and reduced cutting resistance
during pocket and contour machining.
6° Positive End Rake
The positive end-edge rake helps reduce cutting
pressure during pocket-bottom and shoulder machining.
12° Positive Peripheral Rake
The positive peripheral rake creates a sharp
cutting action for aluminum walls, profiles
and peripheral surfaces.
1200-Grit Precision Grinding
Fine grinding with a 1200-grit grinding wheel
helps maintain edge sharpness, reduce microscopic
defects and limit burr formation.
Low Cutting Resistance
Sharp positive-rake geometry helps reduce rubbing,
cutting pressure and unnecessary heat generation
during aluminum machining.
Reduced Built-Up Edge
Sharp cutting edges, sufficient flute capacity
and the optional DLC coating help reduce aluminum
adhesion under suitable machining conditions.
Corner Radius Accuracy Within 5 μm
Walter HELICHECK PLUS measurement supports
corner-radius and profile control within
approximately 5 μm for repeatable pockets,
shoulders and transition features.
Improved Surface Consistency
Precision-ground cutting edges help reduce visible
surface differences between adjacent machining
passes and improve overall workpiece appearance.
50× Microscopic Edge Inspection
Every tool is inspected under 50× magnification
to check for visible edge chipping, serrations
and abnormal cutting-edge defects.
Walter Five-Axis Grinding
Walter five-axis precision grinding supports
stable dimensions, consistent flute geometry
and repeatable corner-radius profiles.
Uncoated and DLC Rainbow-Coated Options
Coating selection should be based on the aluminum grade,
silicon content, cutting parameters, lubrication condition
and required tool life.
