Exploring the Features of the Nachi AQUA EX Flat Drill

The NACHI AQUA EX Flat Drill delivers precise 180° flat-bottom holes with minimal burrs, excellent chip evacuation, and exceptional tool life. Designed for demanding CNC machining applications, it eliminates secondary machining operations while improving productivity across the automotive, aerospace, medical, oil and gas, and general manufacturing industries.
What Makes the NACHI AQUA EX Flat Drill Different?
The NACHI AQUA EX Flat Drill features a true 180° cutting edge that produces accurate flat-bottom holes without interpolation or secondary finishing. Unlike conventional drills, its specialized geometry minimizes burr formation, improves chip evacuation, reduces cutting forces, and helps minimize tool deflection.
Manufactured from premium carbide and protected by NACHI's advanced AQUA EX coating, the drill provides outstanding wear resistance, heat resistance, and machining stability for high-performance production environments.
Benefits of the NACHI AQUA EX Flat Drill
- Produces true 180° flat-bottom holes with excellent dimensional accuracy.
- Reduces burr formation, minimizing secondary deburring operations.
- Excellent chip evacuation improves reliability during deep-hole drilling.
- High wear and heat resistance extends tool life.
- Reduced cutting forces help improve hole quality and minimize tool deflection.
- Compatible with CNC machining centers and automated production environments.
Machine More Materials with One Drill
The NACHI AQUA EX Flat Drill is engineered for machining a wide range of materials, including carbon steel, alloy steel, stainless steel, cast iron, aluminum alloys, and many non-ferrous materials. Its advanced coating and optimized cutting geometry deliver reliable performance across multiple applications while helping reduce tooling inventory.
The drill is particularly effective for applications requiring flat-bottom holes on inclined, curved, or irregular surfaces where conventional drills struggle.
One Drill Replaces Multiple Operations
The NACHI AQUA EX Flat Drill eliminates the need for center drilling or end milling before drilling on angled or curved surfaces. Its specialized geometry enables one-step drilling with minimal burr formation, reducing cycle times and simplifying machining operations.
This makes it an excellent choice for CNC machining centers producing components for aerospace, automotive, medical devices, oil and gas, and general precision machining.
Flat Bottom Drill vs. End Mill
Although flat bottom drills and end mills may appear similar, they are designed for different machining operations.
- Flat Bottom Drill: Designed exclusively for axial drilling with optimized chip evacuation, true 180° flat-bottom holes, excellent centering, and reduced burr formation.
- End Mill: Designed for side milling, slotting, profiling, and interpolation. Chip evacuation inside deep holes is less efficient, and end mills typically leave a slight dish angle rather than a perfectly flat bottom.
When producing precision flat-bottom holes, a dedicated flat-bottom drill delivers superior accuracy, faster cycle times, improved chip control, and better surface finish than an end mill.
Increase Productivity While Lowering Costs
The NACHI AQUA EX Flat Drill helps manufacturers reduce machining costs by combining multiple operations into a single drilling cycle. Faster feeds and speeds, longer tool life, reduced tool changes, and fewer secondary operations all contribute to improved machine utilization and lower cost per hole.
Whether machining prototype components or high-volume production parts, the AQUA EX Flat Drill delivers consistent, repeatable performance that helps maximize productivity.
