DC-2525 1/4" Down-Cut End Mill

1/4" Down-Cut End Mill

Tungsten Carbide with Nano Blue Coating

Overview
This 1/4" down-cut end mill is designed to push chips downward into the material, producing an exceptionally clean top surface. It’s the go-to choice when edge quality on the top face matters more than chip evacuation.

Manufactured from solid tungsten carbide and finished with a Nano Blue coating, this bit performs best on CNC machines equipped with spindles capable of maintaining consistent RPM under load.

Why Use This Bit

• Leaves a very clean top surface with minimal tear-out

• Ideal for visible edges and final passes

• Nano Blue coating improves heat resistance and tool life

• Excellent control on plywood and veneered materials

• Best used with good dust collection and conservative depths

Spindle RPM & Feed Guidance
Down-cut tools trap chips, so lighter passes are important:

• RPM: 16,000 – 20,000

• Feed Rate: 120 – 200 IPM

• Plunge Rate: 40 – 60 IPM

Avoid aggressive depth of cut. Shallow passes and steady feed rates prevent heat buildup and chip packing.

Best Applications

• Plywood and veneered plywood

• MDF

• Hardwood

• Softwood

• Laminated materials

Specifications

• Flutes: 2

• Cutting Diameter: 1/4"

• Cutting Length: 1.5"

• Shank Diameter: 1/4"

• Overall Length: 2.75"

Notes

• Not ideal for deep pocketing due to chip evacuation limits

• Use dust collection to prevent chip buildup

• For through-cuts, consider pairing with an up-cut or compression bit depending on material
