Amana Tool's high mirror-finish solid carbide up-cut spiral ball nose router bits are designed to eliminate tool marks that commonly appear when used with plastic and solid surface materials. Due to the highly polished finish and unique tool geometry, the spiral ball nose router bit delivers superior surface finish of at least 28 Ra (roughness average) in various materials. The up-cut router bits also eject chips up, to help prevent chip out on the bottom of the material.

Constructed of special grade solid carbide, the Amana Tool spiral ball nose router bits last longer than traditional router bits and deliver superior cutting performance with plastics. The bits are ideal for use in a variety of applications spanning the mechanical, medical and woodworking industries.

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.
