High-Performance Metal Removal & Deburring Solutions for Global Aviation MRO
Pan American Tool offers a complete line of high-grade tungsten carbide rotary burs designed specifically for demanding aerospace applications. Ground with micro-grain carbide, our bur line features optimized tooth geometries that deliver superior tool life, smooth surface finishes, and controlled chatter during hand-held die grinder operations in airline maintenance hangars, defense depots, and OEM production facilities.
Choosing the Correct Flute Cut Geometry for Aircraft Alloys
Achieving optimal stock removal and tool life requires matching the bur cut style to workpiece hardness and operator control conditions. Our application team outlines key cutter performance characteristics below:
Single Cut Flute Geometry
Primary Applications: Cast iron, high-carbon steel, copper, brass, and ferrous alloys.
Single cut burs feature right-hand spiral flutes that produce long continuous chips. Ideal for general-purpose metal removal, heavy deburring, and leaving a smooth, uniform surface finish without gouging.
Double Cut Flute Geometry
Primary Applications: Hardened steels, stainless steel, titanium, and Inconel® alloys.
Features intersecting left- and right-hand ground flutes. Breaks chips down into granular particles, significantly reduces operator fatigue, improves tool control in hand-held pneumatic die grinders, and resists loading at lower operating speeds.
NF / Aluma-Cut Flute Geometry
Primary Applications: 2024/7075 aircraft aluminum, magnesium, plastics, and soft metals.
Designed with open, high-helix polished flutes that maximize chip clearance. Prevents soft aluminum from welding to cutting edges under high RPM, enabling aggressive metal removal rates without surface loading.
Bur Cut Style vs. Aerospace Workpiece Compatibility Matrix
Recommended starting guidelines for air-motor tool speeds, cut types, and workpiece material pairings in airframe repair and structural assembly.
| Workpiece Material | Recommended Cut Style | Optimal RPM Range (1/4" Head) | Operating Advice & Best Practices |
|---|---|---|---|
| Aircraft Aluminum (2024, 7075) | Aluma-Cut / NF Non-Ferrous | 20,000 – 30,000 RPM | Use high air motor speeds with light pressure. Open flute design prevents chip packing in soft skins. |
| Stainless Steel & Heat Treated Steels | Double Cut Carbide | 15,000 – 22,500 RPM | Cross-cut geometry breaks chips and minimizes chatter. Maintain steady feed to extend tool edge life. |
| Titanium Alloys (Ti-6Al-4V) | Double Cut Carbide | 12,000 – 18,000 RPM | Run at lower surface speeds to manage thermal friction. Avoid dwelling to prevent work hardening. |
| Inconel® & Nickel-Based Alloys | Double Cut / Heavy Duty | 10,000 – 15,000 RPM | Requires rigid setup and constant tool motion to minimize heat buildup on high-temp engine components. |
| Deep Pocket Airframe Cavities | 6" Reach Extended Shank | Max 15,000 RPM | Never start an extended shank bur outside the workpiece enclosure to prevent shank bending. |
| Sheet Metal Hole Deburring | Burraway In/Out Deburring Tool | 1,000 – 2,500 RPM | Cam-actuated blade deburrs both top and bottom edges of drilled rivet holes in a single fast pass. |
