The NAD 3 Flute DLC End Mill is designed for high-speed aluminum machining. Its 0.6 μm carbide substrate, low-friction DLC coating, large rake angle, and 45° helix geometry provide smooth chip evacuation, reduced cutting resistance, and stable tool life.
The NAD 3 Flute DLC End Mill is designed specifically for efficient machining of aluminum and other non-ferrous materials.
It combines a 0.6 μm carbide substrate with a low-friction DLC coating to reduce cutting resistance and improve chip flow during high-speed milling.
The tool’s sharp cutting geometry, large rake angle, and 45° helix angle help produce a smooth cutting action while reducing cutting heat and the risk of material adhesion.
This makes the NAD suitable for aluminum machining applications where productivity, surface finish, and consistent tool life are important.
Aluminum can adhere to the cutting edge during machining and form built-up edge, especially when cutting speed and material removal rates increase.
The NAD uses a low-friction DLC coating to reduce friction between the tool and workpiece.
The coating also helps limit aluminum adhesion and built-up edge, supporting a cleaner cutting edge and more consistent machined surface.
DLC-coated end mills are widely used for aluminum and other non-ferrous materials because of their lubricity and resistance to welding or material buildup.
The NAD uses a 0.6 μm carbide substrate to provide a stable cutting edge for aluminum machining.
The fine-grain carbide supports edge strength and wear resistance during high-speed milling.
The DLC coating provides low friction and strong resistance to material adhesion.
This helps reduce cutting force, frictional heat, and the tendency of aluminum chips to stick to the cutting edge.
The 3-flute design provides a balance between chip space, cutting-edge engagement, and productivity.
Three-flute DLC end mills are widely used for high-speed machining of aluminum and other non-ferrous materials.
The 45° helix geometry provides a smoother cutting entry and supports efficient chip evacuation.
This is especially useful in high-speed aluminum machining, where chip removal and heat control are important.
The large rake angle creates a sharper cutting edge and reduces cutting resistance.
This helps the tool cut aluminum more freely while reducing the cutting load on the spindle and workpiece.
Poor chip evacuation can cause chips to recut and increase cutting heat.
The 3-flute geometry and 45° helix angle help move chips away from the cutting zone for smoother machining.
Aluminum can weld to the cutting edge and form built-up edge.
The low-friction DLC coating helps reduce material adhesion and keeps the cutting edge cleaner.
A dull or poorly configured cutting edge can increase cutting force during aluminum milling.
The sharp geometry and large rake angle reduce cutting resistance for a lighter cutting action.
High-speed aluminum machining can generate heat and accelerate wear when tool geometry and coating are not well matched to the application.
The DLC coating provides lubricity and wear resistance to support more stable tool life under high-speed conditions.
Built-up edge, unstable chip flow, and tool wear can affect the machined surface.
The NAD’s sharp cutting geometry and low-friction DLC coating help support a more consistent surface finish.
The NAD is primarily designed for:
The exact tool and cutting conditions should be selected according to the workpiece alloy, machine capability, tool diameter, and machining operation.
The NAD 3 Flute DLC End Mill is suitable for:
It is particularly suited to applications where fast chip evacuation, low cutting resistance, and good surface finish are priorities.
For demanding aluminum machining, minimum quantity lubrication (MQL) is recommended when the machining setup supports it.
A small amount of cutting oil can provide lubrication and help control heat while reducing the tendency of aluminum to adhere to the cutting edge.
Compressed air can also be used to aggressively clear chips from the cutting zone, helping prevent chip recutting and accumulation around the tool.

The NAD is designed around the specific cutting behavior of aluminum rather than general-purpose milling.
Its combination of DLC coating, 3-flute geometry, large rake angle, and 45° helix helps control friction, chip flow, cutting resistance, and material adhesion.
This makes it a practical choice for high-speed aluminum machining where productivity and surface quality need to be maintained together.
Different aluminum alloys and machining operations may require specific tool dimensions or cutting geometries.
JimmyTool supports custom carbide end mills based on customer drawings, samples, and application requirements.
Custom solutions can be developed according to tool dimensions, flute configuration, geometry, coating, carbide grade, and machining conditions.
For a custom inquiry, provide the workpiece alloy, required tool diameter, machining operation, cutting conditions, quantity, and drawing or sample where available.
