Solid carbide Spiral 'O' flute aluminum cutting router bits use the highest quality sub-micrograin carbide, have a special proprietary edge processing system and feature a super high polished cutting edge with a unique “mirror finish”, resulting in clean cuts, less chance for chip re-welding, a superior surface finish and a longer tool life. The Spiral ‘O’ flute sharpening/finishing process increases feed rates, allowing for more linear feet routed in less time. Excellent for cutting:
- Aluminum Alloys (Al-Alloy)
- Aluminum Composite Materials (ACM)
- Aluminum Composite Panel (ACP)
- ALPOLIC® Copper Composite Material (CCM)
- Titanium Composite Material (TCM)
- And Other Non-Ferrous Metals
Available in both metric and inch sizes, these router bits are specifically designed for a variety CNC machining applications. Continuous improvements in cutting performance, the unique carbide polishing process, tool design & geometry make these router bits perfect for routing signs and displays. Signmaking (signcrafter) router bits were originally developed in Europe specifically for professional sign makers. Today, CNC routers have become the tool of choice for sign makers, moving beyond printers and vinyl cutters. Durabond is a polyethylene core with 0.3mm colored aluminum sheet on either side. It is a pre-finished product that requires no decoration.
- Industrial quality
- Single flute design
- Super high flute mirror finish results in better cut quality
- Right hand helix/right hand cut

- Longer tool life
: "Why didn't you tell me that the bit (#51408) would cut endlessly through my material without ever breaking? I wouldn't have wasted my money ordering 4 of them!! Hehe, seriously, this bit is churning out some beautiful work. I've doubled my speed and cut off my oil mist." Dennis, LA
For optimal results and to extend tool life please use mist lubricant system or air cooling. Please inspect cut and adjust accordingly.

51470 and 51472
reduce RPM & Feed Rates (IPM) by 30-50% to prevent tool breakage due to extremely small diameter (D). These bits are high finish (not mirror finish due to small diameter).
51489 has a special point for improved bottom finish.
: For aluminum cutting please lubricate.
: The recommended feed rate for Aluminum is 3 M/min or 120 inch/min at 18,000 RPM.
