Description
Product Overview
This carbide square end mill is designed for dynamic milling,
roughing, side milling, shoulder machining, pocket machining
and controlled semi-finishing of titanium alloy components.
It combines an ultra-fine carbide substrate, 12% cobalt content,
HSR118 high-temperature anti-adhesion coating, an arc-formed
U-shaped flute, an 8° positive rake angle, a 43° helix,
87°/93° unequal tooth division and a chip-breaker groove
to support high-load machining and stable chip evacuation.
Recommended Machining Applications
The square cutting profile, high-capacity flute and chip-breaker
design support titanium alloy operations requiring efficient
material removal, flat-bottom cutting and controlled cutting loads.
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.
Side Milling
Designed for titanium alloy walls, straight profiles
and peripheral surfaces requiring stable engagement.
Shoulder and Pocket Machining
Supports shoulder walls, flat-bottom pockets and stepped
titanium features requiring a square cutting profile.
Designed for Titanium Alloy Machining Challenges
Titanium alloys generate concentrated cutting heat, strong material
adhesion and high cutting loads. The coating and flute geometry
are designed to control chips, cutting resistance and built-up edge.
Chip and Heat Control
- Arc-formed U-shaped flute increases 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
Adhesion and Cutting Stability
- HSR118 coating helps reduce titanium adhesion
- Coating retains stable hardness at elevated temperature
- 87°/93° unequal division helps suppress vibration
- 12% cobalt supports substrate toughness
- Controlled edge preparation improves consistency
- Rigid toolholding and low runout are recommended
Square End Mill Geometry and Cutting Performance
The carbide substrate, HSR118 coating, arc-shaped flute,
unequal tooth division and chip-breaker design work together
to support stable titanium roughing and dynamic milling.
Ultra-Fine Carbide Substrate
Ultra-fine carbide powder 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 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 chemical affinity
with titanium, helping limit material adhesion,
built-up edge and tool sticking.
Arc-Formed Flute Design
The arc-shaped flute supports cutting-load distribution,
chip flow and stable machining of difficult titanium
alloy components.
U-Shaped Flute Profile
The U-shaped flute provides increased chip capacity
and supports efficient chip evacuation during roughing
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
side milling and dynamic machining.
87° / 93° Unequal Tooth Division
The unequal tooth 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
efficiency.
Flat-Bottom Cutting Profile
The square-end geometry supports flat-bottom pockets,
shoulder machining, slots and planar titanium features.
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 preparation value controlled within ±3 μm.
Walter Five-Axis Grinding
Walter five-axis precision grinding supports
cutting-edge sharpness, dimensional accuracy
and repeatable square-end geometry.
HELICHECK PLUS Measurement
Walter HELICHECK PLUS profile measurement supports
accurate inspection of tool dimensions, cutting geometry
and flute profiles.
150× and 300× Inspection
150× optical inspection and 300× high-definition
appearance inspection help verify cutting edges,
coating condition and surface quality.
