These router bits are made with an extra-long reduced shank section for deeper reach and better chip clearance. Amana Tool®'s Modern Materials Finishing Geometry (MMFG) incorporates high shear, multi-flute and ZrN coating designed for the ultimate combination of finish and tool longevity in aerospace materials. Modern-day materials present challenges to the fabricator, using these special multi-flute edge tools featuring ZrN ceramic coating addresses these challenges with a winning geometry combination.

The simultaneous 3 axis motion with the appropriate software allows full 3D capability that provides sign and 3D model makers the ability to work with any material.

Specially designed for 2D and 3D CNC profiling and carving in plastic, aluminum & wood with CNC machines. The high-shear ball nose tips cut smooth 2D and 3D contours with reduced stepping while the proprietary ZrN coating (applied by the physical vapor deposition coating process) provides high resistance to wear, sharper cutting edges, extended tool life and less friction and heat buildup. Some of Amana Tool carving tools, as you can appreciate have a very small diameter therefore any material chip-loads need to reflect that small size. It can however withstand RPM’s up to 60,000 RPMs. A directed air-blast to keep chips away along with cooling the tool and work piece are always welcome.

Tools are manufactured with high balance that allows them to run up to 60,000 RPMs. Adjust your chip load and feed rate accordingly.

Applications:
  • A perfect bit for 3D carving

Benefits of Zirconium Nitride (ZrN) Coating
  • Creates a harder and tougher cutting edge allows for a prolonged cutting edge life and helps to prevent the build-up of material in the flutes while cutting
  • Have the tendency to run/spin much faster than an uncoated tool
  • Optimized flute geometry and low Total Indicated Runout (TIR) guarantees clean cuts, essentially eliminates sanding and reduces chatter (where the machine or work piece vibrates) under high chip loads (when used with low TIR spindles)
  • High flute volume supports high feed rates and chip loads
  • High aspect ratio for single pass deep-reach cutting
  • Flute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic composites

Milling Plastics:
In a milling application, all plastics tend to behave differently so attention must be paid first and foremost to heat input, as that greatly impacts surface finish and chip control.

 Suggested starting spindle speed might be 18,000 RPM, there needs to be some experimenting on the part of the programmer to best find an acceptable finish.

Faulty bit and awful customer service from KJP

Had an issue with one of the two I purchased. Contacted Amana who told me to get a RMA from KJP. My initial contact was ignored (no response then a confirmation I was being ignored when someone accidentally replied all instead of sending a bcc) Then I was offered the opportunity to return the bit via post at my expense (don't live in Ottawa no mo') provided it had not been used. In my original email I said I got home and used it. The issue was it marred the work and the only way one could see that is if ya used the bit.

Turns out there was a problem the bit was defective and Amana took care of me without any assistance from KJP.

Was a gross interaction and I don't know why Andrew was such a meanie Richard head from the jump.

Really good bit. The pilot drill broke pretty early on. Seems to be a somewhat common issue. So I happened to be back in Ottawa and decided to pop in to KJP. Ran in to Andrew, who had no idea who I was, and asked about buying a replacement pilot drill. He was rude af and told me they don't stock the drill but I could go online and order it tho...

That was very helpful because I wasn't aware you can buy stuff on the internet.
