PCD Special-Form Drill – Custom Geometry & Flat-Bottom Options | Aoshiji® Custom Tool

Overview

The PCD Special-Form Drill from Aoshiji® Custom Tool is a precision-engineered diamond drill designed to machine custom hole geometries in a single operation. Whether the requirement is for flat-bottom holes, radiused bottoms, chamfered edges, stepped bores, or countersunk features, this tool consolidates multiple operations into one efficient process.
With polycrystalline diamond (PCD) cutting edges, it delivers exceptional wear resistance, superior dimensional accuracy, and extended tool life, making it the ideal solution for high-volume CNC machining of aluminum alloys, composites, and non-ferrous metals.

Applications

• Custom hole drilling in aluminum, copper, brass, magnesium, plastics, and composites

• Flat-bottom, radiused, conical, stepped, or countersunk holes in one pass

• Automotive & aerospace components requiring complex bore geometries

• Precision engineering & mold-making industries with demanding tolerance requirements

• Mass production environments where cycle time and cost-per-part must be minimized

Key Features

• Custom geometry in one pass – Eliminates multiple drilling tools and setups

• PCD cutting edges – Superior wear resistance, consistent performance in non-ferrous machining

• Multi-feature design – Capable of drilling with integrated chamfers, radii, steps, or counterbores

• High concentricity – Ensures bore accuracy and consistent bottom profiles

• Optimized flute design – Efficient chip evacuation for complex hole shapes

• Flexible mounting – Straight, Weldon, or custom shank types with optional through-coolant

Benefits

• Reduced cycle time by integrating multiple operations into one tool

• Lower tool inventory & changeover costs

• Improved dimensional accuracy with micron-level tolerance control

• Extended tool life compared with carbide or HSS drills

• Superior surface finish and burr-free edges, reducing secondary operations
