Description

O Flute Router Bit O Flute Router Bit O Flute Router Bit O Flute Router Bit O Flute Router Bit O Flute Router Bit O Flute Router Bit What makes an O-flute flute bit different? Its O-flute design provides ample chip space for smooth cutting and efficient chip removal. Can I use this router bit on aluminum and brass? Yes. It is suitable for aluminum, brass, copper, soft metals, acrylic, wood, and other compatible materials. What types of cuts can this bit make? Ideal for slotting, grooving, pocketing, profiling, engraving, trimming, and edge milling. What is the difference between upcut and downcut? Upcut lifts chips away from the cut, while downcut pushes chips downward for better top-edge control. When should I choose an upcut or downcut bit? Choose upcut for efficient chip evacuation; choose downcut when a cleaner top surface is preferred.

  • Very high performance
Size: 1/8" DIA - 1/2" CL - 1/4" SHK Number of Items: 1
Deadly sharp, very high quality. Cuts through 6061 aluminum like it was balsa wood. Good price for what you get. I used a a wood router to cut a 1/8 x 1/8 inch groove into a 6 foot length of bar stock with no problems at all. Added the tiniest amount of cutting fluid. Took longer to setup than to make the cut. ... show more

Great quality CNC bit. It cuts cleanly, stays sharp, and performs exactly as expected. Installation was easy, and the finish is smooth with accurate results. Excellent value for the price—I would definitely buy this bit again.
