Genmitsu 40pcs End Mills CNC Router Bits, 1/8" Shank

The bits came neatly organized, cut cleanly, and have held up well so far. Excellent variety for CNC projects, especially for beginners and hobbyists. Very happy with this purchase and would recommend it.

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.

The bits seem to work well for the price, they have been good to learn my new machine with. - But, I being a beginner, have no idea what bits are what, and what size they are. Nothing is marked or labelled, and there is no literature with the box. I have to come back to the listing to try and figure out what size is what and use a micro caliper to measure it. I've now screenshot the size charts to help when trying to program the size in the CNC program.

A good variety of bits for a reasonable price. I use these on a Genmitsu 4040 PRO and have had good success. They're sharp and sturdy and cut cleanly. These are compatible with any 1/8" collet. I haven't had them long enough to determine wear, but the ones I have used have held up well.

These bits work great for my 500-watt Lunyee 3018 Pro Max CNC Machine. These are a must have for this machine.

I have to say for a 1mm bit. This is pretty good. It is the 1mm titanium coated but in this video. These helix bits successfully carve hard purple heart wood, where normal bits failed

These milling bits work great for non-metal materials like wood, plastic, or composites. However, when it comes to cutting aluminum, they fall short. While the description claims they can handle aluminum, in practice, you’ll get one use at best before the bit dulls or wears out. If you’re planning to cut aluminum, look for higher-quality bits specifically designed for metals. For non-metal projects, though, they perform well and are worth considering. Bottom Line: If you’re sticking to non-metal materials, these bits are fine. But if aluminum is part of your project, look elsewhere for a more durable solution.

I purchased an inexpensive CNC router. It only came with one type of bit. That type of bit is not one I wanted to use. I purchased these because they were inexpensive and I am new to CNC routing machines. I received a variety of bits and did some testing. They work well for the ametuer that is learning and doesn't have a great deal of money to buy the expensive bits that everyone on YouTube is pushing.

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

They look great tools. Yet to use them though.

ok

Très bonne qualité de fraises, font parfaitement ce qu'on leur demande !

Good value
