40pcs End Mills CNC Router Bits, 1/8" Shank CNC Cutter Milling Carving Bit Set Including 2-Flute Flat Nose & Ball Nose, Nano Blue Coat & Titanium Coat, MC40A

Order was expected with quality milling bits

WAS AS DESCRIBED

The corn mill bits work great from wood to mild steel, on a router or milling machine the flat and ball end mills work about fine for soft materials. On the outer edge of each flute of the 2-flute mills, there is a continuous band of unground steel, which should taper inward- this causes the tool to rub slightly. There is visible variation in the depth of the grinding, causing the unground section to be sized differently along the bit, and even between multiple bit there is a visible difference. I did find two ball end mills that had good edges near the bottom, which I'm pleased with, I just have a hard time understanding how you get so much variation on such a small scale. You get what you pay for, and for what you pay for this is a decent set.

I am fairly new to CNC and lasers. I've been working on CNC and laser projects for over two years now. Cutting with my 24 watt laser takes way too long. So, I've decided to use a router bit about the size of my laser, and cut out my designs. As of lately. I have been doing a lot of mandala's. They are very popular with the ladies. Maybe these CNC router bits will save me some time. So far I am quite pleased with the Genitsu CNC router bits. You receive only a carboard box containing four plastic cases of CNC router bits. No documentation of any kind. So, I printed off all the documentation from the Amazon description(see pic). Since the router bits are all in translucent plastic cases, and you can not see bits. I labeled each case(see pic). This makes it easier for me, instead of popping open each case when I want to find the right router bit. As far as the comments from the other reviews. I have no broken router bits. Searching the internet. The description below is the use for each of the four different router bits that came with this order. I am not one for buying a $12 piece of plywood, finding out I used the wrong CNC router bit, and wasted some good wood. So, a description for each of the four CNC router bits uses is helpful. There may be some veteran CNC'ers out there. And they can just pick up a router bit. Look at it, and know exactly what it's best used for. But, that's not me, maybe later down the road. Spiral Flat Nose End Mills - are versatile cutting tools used for a wide range of applications, including milling, carving, engraving, and slotting. They excel at creating flat-bottomed cuts, ideal for tasks like roughing operations, generating flat surfaces on 3D objects, and making precise 2D shapes. Ball End Mills, also known as Ball Nose End Mills - are primarily used for contouring and profiling 3D parts, especially in mold and die applications. They are also used for milling rounded slots, grooves, and for creating smooth, rounded finishes in various materials. Nano Blue Coated End Mills - are primarily used in various CNC applications and machining processes, particularly where high-speed cutting, high-performance materials, and a clean finish are required. They excel in tasks like 3D relief sculpturing, cutting, engraving, slotting, and milling. Titanium-Coated End Mills are commonly used in machining applications to improve tool life and performance. The coating helps reduce friction, leading to less wear and tear, and can enhance the cutting process by minimizing heat buildup and promoting smoother cutting. Titanium coatings also improve the surface finish of the cut parts and resist oxidation.

Very inexpensive and fruitful. There are many pieces I can use and hopefully, they will all come in handy one day.

My husband loves them have done many projects with them wroth no problems. They work as they should. Speedy shipping and exactly as described

There are a lot of bits here you may never use. All the bits are 1/8 diameter and short. Appear to be good quality. I would not buy these until you have run your CNC for a few projects so you can make a good judgement.

Perfect. Product is exactly as described.

Muy buena calidad, una excelente selección para tener de todo en tu taller
