BC2055 3-Flute DLC Corner Radius End Mill for Aluminum | Solid Carbide

BC2055 is a 3-flute, DLC-coated solid carbide corner radius end mill developed for aluminum alloys and other compatible non-ferrous materials. It is a strong choice when chip evacuation, low material adhesion, and a more durable cutting corner matter more than simply using a sharp square-end tool.

Why BC2055

Aluminum machining often becomes unstable when chips are not cleared efficiently or material begins to build up on the cutting edge. BC2055 addresses that with an open 3-flute geometry and a low-friction DLC-coated surface. The corner radius adds strength at the tool tip, helping the cutter handle contouring and side-milling work with less risk of corner damage than a sharp square end.

Best Suited For

• Aluminum alloys
• Copper and other compatible non-ferrous metals
• Plastics and similar materials where a low-friction cutting surface is useful
• Side milling and contouring
• Semi-finishing and finishing

When to Choose a Corner Radius

Choose BC2055 when the part geometry allows a radius at the internal corner and you want a stronger cutting edge than a square end mill. The selected R value should match the part requirement; a larger radius generally gives a stronger corner, while a smaller radius follows tighter geometry.

How to Choose the Variant

• Cutting diameter: match the feature size and required tool rigidity.
• Corner radius: match the drawing and required edge strength.
• Cutting length: use only as much flute length as the machining depth requires.
• Overall length: use the shortest practical reach to preserve rigidity and reduce vibration.

Important

BC2055 is focused on non-ferrous machining. For steel or stainless-steel work, choose a BB Tool series designed around those workpiece materials and their higher heat requirements.

Cutting conditions should be selected according to the exact alloy, tool diameter, radial and axial engagement, holder runout, machine rigidity, and chip-removal method.
