How to achieve high precision and non convex hole bottom with AMG hollow flat bottom drill?

2025-08-06

In precision machining, flat bottomed holes are often considered one of the difficulties due to their extremely high requirements for bottom flatness and positioning accuracy. Especially when drilling blind holes or stepped holes in materials such as stainless steel and titanium alloys, it is more prone to problems such as protruding holes at the bottom of the hole, burning knives, or poor chip removal. The hollow flat bottom drill launched by AMG is designed to address these pain points.


This high-performance hard alloy drill bit features a unique void design that effectively reduces the friction area with the hole wall, lowers cutting resistance, and significantly improves chip removal efficiency while maintaining rigidity. Combined with the patented flat bottomed blade structure, it can achieve a hole bottom effect without cone angles or protrusions, and there is no need for secondary trimming after processing.


In order to meet different processing needs, AMG offers a variety of specifications for hollow flat bottom drills, covering Ø 3mm20mm, 3D8D depth, and can be equipped with high-performance coatings such as TiAlN and DLC to cope with high temperature and high-strength cutting environments.


Whether in the CNC machining center, mold manufacturing, medical equipment, or aviation parts industries, AMG hollow flat drills can provide stable performance with high smoothness, consistency, and efficiency.


For users who pursue hole bottom accuracy and processing efficiency, this drill bit is undoubtedly a more professional and reliable solution.
