Excellent variety for CNC projects, especially for beginners and hobbyists. Very happy with this purchase and would recommend it. Review: Received Only A Box With Four Plastic Cases Of CNC Bits - 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 desertcart 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. ## Features - High Quality: The Genmitsu end mills are made of ultra-fine 0.2ΞΌm tungsten carbide steel alloy that can keep continuous machining 800 minutes. Moreover, its Nano Blue Coating /Titanium Coating with high hardness and heat resistance enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality. - 2-Flute Spiral Flat Nose & Ball Nose End Mills -- Shank Diameter: 3.175mm, Cutting Diameter: 3.175mm, Cutting Length: 17mm, Overall Length: 38mm. - Two End Mill Sets -- Shank Diameter: 3.175mm, Cutting Diameter: 0.8 - 3.0mm (0.8/1.0/1.2/1.4/1.6/1.8/2.0/2.2/2.5/3.0mm), Cutting Length: 17mm, Overall Length: 38mm, with Nano blue and Titanium coating. - Applicable Materials: Widely used in various materials including plastics, aluminum, circuit board, wood, as well as other precision parts processing. - Wide Compatibility: The MC40A end mills are compatible with most desktop CNC machines, such as the Genmitsu 3018 Series, as well as other industrial CNC machines.
