HQMaster Extra Long Spiral Router Bit Upcut 1/4 Inch Shank Solid Carbide CNC Router Bit with Nano Blue Coating CNC Bits End Mill for Woodwork Mortise Slot Trim

Worked great. I'm very careful at how much I take off with each pass, but did not disappoint in the least. Used it to make square mortises in an arts and craft style stair railings.

Excellent

For the price this bit will get the job done. It doesn't cut the cleanest so I question how sharp it is, but a little sanding has my parts up to scratch. If you want a clean finish straight off the machine you'll have to pay $15-50 more depending where you shop but for me this just hit that good enough line.

Amazon has the finest delivery system and always has a variety of choices and recommedations. I often reveive product overnite, and I have never been disappointed in te service.

This is one of the few bits I've found with a 1/16" diameter and ~3/4" cutting length. It cuts perfectly in HDU and color core plastics.

I bought a pack of 5, and one has already broken after the second use. I made no changes to my CNC settings from using my Amana (46225-K) bit previously. By no means am I endorsing Amana, just haven't found an alternative. I'm currently using the 2nd bit but I've already noticed it leaving a burnt residue on the backside of the wood...hope I got a bad batch. I guess I'm going to have to test their customer service as I'm wanting to return these inferior bits.Update: Today is 27 May 23 and the 2nd of 3 bits used has broken. I bought a pack of 5, so 2 more to go. The problem is when you leave your job unattended and the bit breaks, now you have a destroyed piece of material. I don't know about you but I don't like to babysit my CNC machine.Update: 31 May 23...contacted them and they swiftly gave me a refund. Customer service is excellent. I will give the same product a chance and purchase again to ensure I did not get a defective batch.

Excellent bit, long enough for deep carving

stays sharp, nice long reach… exactly what i need it to be
