This Combination Drill & Chamfer Tool is engineered to perform drilling and chamfering in a single operation, delivering clean hole entry, controlled chamfer geometry, and improved machining efficiency. Designed according to customer drawings, it integrates a precision drill point with a defined chamfer angle—ideal for applications requiring consistent hole quality, reduced cycle time, and stable cutting performance in aluminum, steel, stainless steel, and non-ferrous materials.
Aoshiji® Custom Tool provides precision Combination Drill & Chamfer Tools engineered to perform drilling and chamfering in one pass, eliminating secondary operations and reducing cycle time.
Designed strictly according to customer drawings, this tool integrates a high-accuracy drill point with a controlled chamfer angle, ensuring clean hole entry, consistent chamfer geometry, and stable performance across aluminum alloys, steels, stainless steels, copper alloys, and composite materials.
Our engineering-and-trading team delivers cost-efficient, application-matched tools for both prototype and mass-production machining.Related technical article:Aoshiji® Custom Tool – Chipbreaker Drill for High-Efficiency Machining of 6061 Aluminum Alloy | Case Study
