Review on HQMaster 3 175mm Tungsten Cutting Milling by Larry Blanco

I was asked to rate these bits. First of all, this is a 1-blade spiral cutter. " They're not spherical." They're supposed to cut acrylic plastic very well. I've used a ball point and tried different end mills, but I just couldn't get the smoothness I wanted. I've been using these single-flute spiral cutters at fairly high feed rates and little infeed .If you need an accurate shoot email me.Their quality is exceptional.I've done at least half a dozen jobs in one go and haven't noticed any dullness so far.I would highly recommend them if you're soft working on plastics or making acrylic sheet surfaces with LED lights Thank you for your service and honesty of these beats Best regards, Tim M immediately
