JERRAY Chamfering Mill, Carbide with TiAlN Coated, 4 Flutes, 60 Degree V-Groove Chamfer End, 1/4" Diameter

I have used this in my cnc machine center successfully to engrave Delrin, mild steel and 303 stainless. While burs are inevitable, it did a wonderful job. I have not used it enough to evaluate tool life

Works great on aluminun though Ive mostly been using is on stuff like Derlin. Also works great on other machinable plastics.

Great for hardwood CNC router.

I don't know if I got a bad one but this V bit does not make very clean cuts like others I've tried from Yonico, whiteside and such. When v-carving black acrylic on my CNC the lines come out very fuzzy. I've found a use for it by making the vcarve depth a very small 0.4-0.5mm which results in a rough white finish on the black acrylic which works for my coaster project, it leaves some burrs around the edges which can be rubbed off with your finger or a brush so this purchase wasn't a complete loss. I thought maybe it was that a 4 flute just isn't good for acrylic so I attempted to use it to chamfer/deburr some 6061-T6 aluminum at a slow and cautious feed rate and 0.2mm DOC. For the first time ever I got some awful chatter from my 1.5kw spindle. Not horrible if you're looking for that rough white finish on black acrylic, otherwise go with something better!

What can I say it does the job.

Much better performance than a two flute.

Este artículo dice 10 piezas de 3,275 por lote y me enviaron una sola pieza de un tamaño mucho más grande y no me sirve para nada. Esperé mucho para que me llegará a mi país República Dominicana. La pieza que me llegó aparenta se buena pero no puedo montarla en mi CNC ya que es muy grande.

Really nice cutter
