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

The AMG high-flatness 2 flutes carbide flat drill is specifically designed for blind hole drilling in soft metals such as aluminum, copper, and brass. Made from 0.6μm micro-grain carbide rods, it ensures high stability during high-speed cutting while achieving a truly flat hole bottom without arc marks, meeting the needs for subsequent tapping, positioning, and precision assembly.

Widely used for blind hole drilling, flat-bottom hole drilling, and non-flat surface drilling on aluminum parts, copper parts, and brass components, facilitating subsequent tapping and precision positioning, improving assembly efficiency while reducing secondary finishing.

• 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°

The 180° flat tip enables a completely flat bottom during drilling, avoiding arc marks that affect assembly. The double-edge guiding design helps align the hole wall during blind hole drilling, maintaining straightness and precision. The 30° helix angle ensures smooth chip evacuation, preventing chip clogging and sticking inside blind holes while ensuring stable high-speed cutting.

• Truly flat-bottom holes for tapping and precise assembly
• Stable, efficient chip evacuation prevents clogging and sticking
• High straightness and diameter accuracy during drilling
• Suitable for soft metal blind hole drilling applications
• AMG supports OEM customization with fast delivery

AMG is equipped with advanced WALTER and SAACKE grinding machines and ZOLLER inspection systems, implementing a strict four-step inspection process to ensure every tool achieves flat-bottom holes, precision straightness, and efficient chip evacuation in blind hole drilling.
