Custom Corner Radius End Mill aluminum Overview
This custom 4-flute solid carbide corner radius end mill is engineered for stable side milling, profiling and edge finishing in aluminum, copper, brass and other non-ferrous materials. Unlike common 2-flute or 3-flute aluminum cutters, its four-flute geometry provides a stronger core and more cutting contacts for finishing and low-to-moderate radial engagement. The reinforced corner radius improves edge strength and part-fillet control, while polished uncoated or DLC-coated configurations can be matched to chip-adhesion, surface-finish and tool-life requirements.
Key Configuration
Custom Corner Radius
The R value can be matched to the component fillet while strengthening the end-to-peripheral edge transition.
Four-Flute Rigidity
A stronger core and four cutting contacts support stable profiling and finishing with controlled engagement.
Polished or DLC Surface
Low-friction surface options help control aluminum adhesion and maintain cleaner chip flow.
Key Product Advantages
Stronger Corner
Improved corner strength compared with a sharp-edge square end mill.
Productive Engagement
Four flutes provide more cutting contacts per revolution for stable non-ferrous finishing.
Reduced Adhesion
DLC or polished surfaces help reduce built-up edge in non-ferrous machining.
Drawing-Based Supply
Diameter, radius, flute length, shank and overall length can be customized.
Recommended Milling Operations
The four-flute design is best suited to finishing and controlled-engagement operations where rigidity and additional cutting contacts are preferred over maximum flute space.

Corner Radius End Mill Application Guidance
- Radius Selection: Select an R value equal to or smaller than the required part fillet.
- Four-Flute Engagement: Use controlled radial engagement to maintain chip space and stable cutting in aluminum.
- Pocket Machining: Confirm center-cutting and entry capability before plunging or helical interpolation.
- Toolholding: Use a low-runout holder and minimize unnecessary overhang, especially for small DC and small R sizes.
- Chip Control: Use effective air blast, mist or suitable coolant to prevent chip packing and aluminum recutting.

FAQ sur les produits et leurs applications
Selection and application guidance for aluminum and non-ferrous material machining.
What materials is this corner radius end mill designed to machine?
It is primarily designed for aluminum and aluminum alloys. Suitable configurations can also be reviewed for copper, brass and other machinable non-ferrous materials. The cutting-edge geometry and surface treatment should be selected according to the exact alloy, silicon content and machining conditions.
What is the advantage of the four-flute design?
The specialized four-flute geometry provides a stronger tool core and more cutting contacts per revolution than common 2-flute or 3-flute aluminum cutters. It supports stable profiling, contour milling, edge finishing and semi-finishing when controlled radial engagement and effective chip evacuation are used.
What machining operations are suitable for this tool?
It is suitable for side milling, profile milling, contour machining, edge finishing and selected semi-finishing operations. The corner-radius geometry strengthens the transition between the end cutting edge and peripheral cutting edge while producing a controlled part fillet.
How should the corner radius be selected?
Select a corner radius equal to or smaller than the required component fillet. The final R value should also be reviewed according to the cutting diameter, machining allowance, required corner strength and finished-part geometry.
Should I choose a polished uncoated or DLC-coated tool?
A polished uncoated tool is suitable for general aluminum machining where a sharp cutting edge and smooth chip flow are priorities. DLC coating can be selected when lower friction, reduced aluminum adhesion or improved wear resistance is required.
Is this four-flute end mill suitable for full-width slotting?
The four-flute configuration is better suited to profiling and controlled-engagement operations. For full-width slotting or heavy aluminum roughing, a 2-flute or 3-flute aluminum end mill normally provides more flute space for chip evacuation.
FAQ sur les commandes et la personnalisation
Information for distributors, tooling brands and customers requesting standard or drawing-based configurations.
What reference sizes are available?
The reference series includes selected cutting diameters from Ø1 to Ø12 mm with multiple corner-radius, shank-diameter and overall-length combinations. Final availability should be confirmed according to the complete tool specification and required quantity.
Can non-standard dimensions be manufactured?
Yes. Cutting diameter, corner radius, flute length, neck dimensions, shank diameter, overall length and dimensional tolerance can be reviewed according to the drawing and machining application. Final dimensions are confirmed before production.
Can I order samples before placing a bulk order?
Yes. Sample orders and custom-size trials can be reviewed according to the required dimensions, surface treatment and quantity. Please contact us to confirm sample availability, production cost and delivery charges.
What is the lead time?
In-stock standard configurations can normally be dispatched within 1–3 working days. Production time for custom dimensions, special corner radii, DLC coating, laser marking or private-label packaging is confirmed after the specification and order quantity have been reviewed.
Proposez-vous le marquage OEM et le conditionnement sous marque de distributeur ?
Yes. Customer logos, tool codes, cutting dimensions and batch numbers can be laser marked according to the available shank area. Custom labels, protective tubes and private-label packaging can also be supplied for wholesale and distribution orders.
What information is required for an accurate quotation?
Please provide the workpiece material, cutting diameter, corner radius, flute length, shank diameter, overall length, machining operation, axial depth ap, radial engagement ae, polished or DLC-coated surface, tolerance requirements and order quantity. A tool or component drawing is recommended for custom projects.
