Amana - 51593 - 1/4" Steel Cutting Multi Helix

Amana - 51593 - 1/4" Steel Cutting Multi Helix

51593 - Steel Cutting Multi Helix (Solid Carbide, Square Bottom, Up-Cut)

  • Shank: 1/4"
  • Diameter: 1/4"
  • Cutting Length: 5/8"
  • Overall Length: 2-1/2"
  • Flutes: 4 Flute Up-Cut

Amana Tool's variable helix tools are the superstars of carbide end mills for professionals and hobbyists alike. The variable helix eliminates harmonic chatter, so critical when surface finishes part dimension tolerances and tool life are of the utmost importance. Premium Aluminum Titanium Nitride (AlTiN) coating provides quantum increases in productivity either in terms of speed or longevity with or without coolant.

They are outstanding tools for peripheral milling and can take aggressive cuts along the full length of the overall flute length with no issues. They last much longer than general purpose end mills partly because they are coated partly because they dampen vibration which tends to break a sharp cutting edge down very quickly. For use with manual and automatic milling machines, as well as the most sophisticated CNC machines.

4 Flute unique variable design for faster speeds and feeds.
Quiet operation & better finishes.
Excellent for cutting
  • Stainless Steel
  • Titanium
  • Cast Iron
  • Steel
  • Cermet*
  • Metal Composite Material (MCM)
*Cermets are composites in which ceramic materials and metals join together.
AlTiN Coating
  • Extra wear resistance
  • Allows for faster feed and speed rates
  • Cutting edge protected from wear
  • Better chip evacuation
  • Less heat build up
  • Superior cutting quality and extended tool life

Warning: Inspect cut quality adjust feed and speed accordingly. Care should be taken to observe proper feeds and speeds according to the workpiece material to avoid damage.

Note: For optimal results and extended tool life use mist lubricant system or air cooling.
Speed and Feed Rate

CNC running parameters based on 1 x Diameter depth per pass:

  • RPM: 18,000
  • Feed Rate: 50 IPM

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.

Amana spiral compression bit

Excellent bit with Spectra finish, very clean cutting leaving very clean top and bottom edges on Baltic Birch plywood
