High Flatness 2 Flutes Carbide Drill Bit For Aluminum Copper Blind Hole Drilling

High flat-bottomed double-edged carbide flat-bottom drill is ideal choice for blind hole machining in soft metals.

In the blind hole machining of soft metals such as aluminum, copper, and brass, achieving a truly flat hole bottom is a processing challenge . The high flat-bottomed 2-edge carbide flat-bottom drill launched by AMG is a professional solution specifically developed to resolve this problem.

Using a 0.6μm ultra-fine grain cemented carbide substrate, with a 180°flat head design, the bottom of the drilled hole is flat, improving the assembly accuracy. It is the preferred tool for precision manufacturing industries such as electronics, aviation, automotive parts, and medical equipment.

Applications

Suitable for blind hole drilling, flat bottom hole drilling, and drilling of non-planar workpieces in soft metals such as aluminum, copper, and brass.

• Material: 0.6μm micro-grain carbide

• Coating: Uncoated / AlTiN / TiN optional

• Flutes: 2 flutes

• Diameter: 8mm

• Flute Length: 20mm

• Overall Length: 100mm

• Helix Angle: 30°

Working Principle

The drill bit adopts 180° flat-bottom structure, can achieve a flat-bottom cutting in blind holes without curved residue, ensuring precision and reliability in the next. The dual-edge guiding design improves the straightness and hole diameter accuracy of drilling. The 30° helix angle ensures smooth chip evacuation, effectively avoiding chip blockage or adhesion in blind holes effectively.

Advantages

True flat bottom hole machining: meeting high-demand processes such as tapping, assembly, and positioning

chip removal performance efficiently : Prevents blind hole blockage and enhances machining stability

High hole diameter accuracy: The guiding structure ensures vertical hole walls and consistent hole diameters

design for soft metals: suitable for high-precision machining of materials such as aluminum, copper, and brass
