They come in a range of angles and tip diameters. The small angles and tips provided on these V-shaped engraving bits produce narrow cuts and small, delicate engraving of lettering and lines. Available on a 6mm shank, or a 3mm shank.

If I end up doing this often enough, I plan to build an enclosure for my Shapeoko. I’ll put a blower on that enclosure, and I’ll plumb it up to a dryer vent. I haven’t gotten that far along, though.

These TCT Straight Routers have extremely sharp cutting edges for plunge cutting, routing grooves, cutting dados, rabbeting and mortising and will achieve a clean, smooth, high quality surface finish.

4. The exception to this rule is diamond drill bits which have a flat end rather than pointed or fluted. (Unless it is a diamond twist drill which is not used for drilling but for expanding already existing holes such as in beads)

Wonderful for use on a wide range of applications on plywood, hardwood, fibreboard, chipboard, softwood, PVC, plastics, acrylics, ABS, MDF, PMMA and more.

Great for large surface area work, roughing end mills have numerous serrations (teeth) in the flutes to quickly remove large amounts of material, leaving a rough finish.

Carbon fiber dust is hazardous. It is conductive, and it gets all over everything. The dust might manage to short circuit something in your laptop. It will get into your router. It will get in your lungs.

I can reduce my number of passes to three if I increase the depth per pass to 1.1 mm. I plan to test this, and I will also be increasing my feed rate.

I wear a mask, and I’m constantly running my little Shopvac knockoff. I would give you a link to the mask I’m using, but I doubt it is really up to snuff. It has a filter, and it doesn’t leave any gaps around my nose. To be properly safe, I should probably look like Barbeque from G.I. Joe.

End mills, slot drills, routers, milling cutters, drill bits, V-bits and burrs - what does it all mean? And which bit do I need for what job? For instance, which are the best end mills? and which is the best end mill for aluminium, and which are the best end mill for stainless steel. This article gives you the low down on milling cutters and CNC tooling and the right tools for the job.

The 400x500 mm 3K carbon fiber sheets are definitely high quality. I ordered those from GetFPV.com. I ordered another sheet of 3 mm 3K carbon fiber from Hobby King. That sheet hasn’t arrived yet, and they don’t stock 400x500 mm sheets. Their prices are quite a bit better, though. You get about 40% more material for your dollar at Hobby King.

Chamfer Mills are used to bevel a wide range of materials, sometimes referred to as countersinks. They will grind and smooth centre holes, deburr, bevel, and countersink on various applications.

Often more expensive, these coatings are added to the bit to reduce wear and friction. However, not all coatings are suitable for all materials and whilst a particular coating may be good for productivity on one material, it may not be on another.

Endmills, routers and milling cutters are those used in a CNC machine, but if you don’t have a CNC machine then you can use Burrs in a rotary tool.

The craft market has recently exploded with exciting compact, tabletop CNC Routers and Mini-milling machines. CNC Routers are now affordable enough to allow DIY enthusiasts access to this high-precision milling tool for carving and engraving.

2. Most drill bits have a spiral groove (flutes) which gives the drill bits a twisted appearance and helps to cut away material as they move up and down in the hole.

Cobalt end mills come at a higher price than HSS but provide high-efficiency milling, better wear resistance and toughness.

Carbon fiber is actually quite easy to cut. Your router doesn’t need a ton of torque or speed—my router’s minimum speed is actually too fast!

Carbide end mills are extremely heat-resistant and used for high-speed applications on some of the hardest materials such as cast iron, non-ferrous metals, alloys and plastics. They have an excellent performance rate and abrasion resistance and can be used on a wide variety of materials.

Quadcopter frames are cut from premade sheets of carbon fiber. The factory stacks layers of carbon fiber, and they impregnate it with epoxy resin. The process generates flat sheets. The sheets I’m using have alternating layers with the carbon fibers rotated 90 degrees. The top and bottom layers have the woven pattern.

There are multiple types of End mills, each designed with a variety of different factors to enable you to choose the right end mill to match the material you’re working on, and the type of project you’re going to use it for.

4. End mills allow for precision parts to be cut, anything from machine parts, jewellery designs, wood engravings, sign making, plastic cutting, mold making and circuit boards.

I’m using 1/16” fishtail endmills that I bought on eBay. They’re about $20 for a pack of 10. I haven’t broken one yet, but I will be sure to keep pushing my feeds higher until I do!

They are sometimes referred to as Corn Cob cutters, or Hog Mills - so-called after the pig who ‘grinds’ away, or consumes, anything in its path, meaning they have high material removal rates.

I chose a depth per pass of 0.8 mm, because I’m cutting 3.2 mm deep on my 3 mm sheets of carbon. That means I can cut all the way through a single sheet of carbon in four passes. Choosing your depth per pass based on the thickness of your material seems smart!

The choice of material for your selected end mill will depend on the hardness of your workpiece and the maximum spindle speed of your machine. A solid carbide end mill will give the best performance, with high accuracy, can be used at higher feed rates, and benefits from a long tool life due to the strength of tungsten carbide.

I am not an expert. I have cut about three quadcopter frames’ worth of parts. Not three complete frames, though. My design process is iterative, so I’ve been replacing parts as I make improvements.

HSS end mills come at a cheaper price, but do not offer the high efficiency, high performance, tool life, or speed capacity of solid carbide end mills.

2. Endmills are available in a wide variety of lengths, diameters, flutes and types, and are chosen according to the material they are cutting and the surface finish required for the project.

I’m not an expert, but as far as I know, there are two common ways to work with carbon fiber. You can shape the woven fabric, then coat it with epoxy. This is a lot like repairing a fiberglass hot tub.

Ball nose mills have a radius at the bottom which makes for a nicer surface finish in your workpiece, meaning less work for you as the piece won’t need to be finished any further.

If your CNC machine can handle hardwood or aluminum, you shouldn’t have any trouble cutting carbon fiber sheets. You certainly don’t need a machine as big or as powerful as the Shapeoko or an X-Carve. You could definitely replicate my success with a small machine like my friend Alex’s SainSmart 3018 Prover CNC.

Most end mills are manufactured from either cobalt steel alloys – referred to as HSS (High Speed Steel), or from tungsten carbide.

So why use an Endmill and not a drill bit? In short, a drill bit moves up and down, and an end mill moves side-to-side (Note: there are endmills available that move in all directions).

I’ve tested all sorts of settings. I’ve gone as high as 800 mm/minute with a cut depth of 0.5 mm. I broke a $20 bit from Carbide 3D on that cut. I’m not sure the speed was the problem, though. My 3 mm carbon fiber sheet came loose during that cut, and I assume that put a lot of stress on the bit.

Are you cutting carbon fiber on your CNC router? Are you having as much success as I am? I’d love to hear about your machine and your process! Leave a comment a below, or stop by [our Discord server][bw] and chat with me about it!

I plan to push my feed rates and depths as high as I can. That’s just what I do. I pushed my 3D printer as fast as it could go. I push my quadcopters as fast as they can go. So why not push my Shapeoko as fast as it can go, too?!

1. End Mills cut rotationally in a horizontal,  or lateral (side to side) direction whereas a drill bit only cuts straight down, vertically into the material.

The helix angle is the space between the cutting edge and the centre of the tool, so the length of cut if you like. The larger the helix angle the more likely it is to be used on softer materials, the smaller the angle the more likely it is to be used on harder and stronger materials.

The math says I should be running my router at 5,000 to 6,000 RPM. My Dewalt router can’t run that slowly. I believe the lowest setting works out to around 20,000 RPM. Too much speed generates heat, and it cuts out dust instead of chips. The heat could be bad for the epoxy, but it hasn’t been problematic yet!

I’ve used up almost half of my first 400x500x3 mm sheet of carbon fiber, and I’ve ordered a less-expensive second sheet from another vendor!

Similar to square end mills/flat end mills but these have a round cutting edge also known as bull nose (not to be confused with Ball nose as mentioned above).

3. End mills are the cutters of the milling world and are used for slotting, profiling, contouring, counter-boring, and reaming.

The list of materials you can cut with a CNC router seems endless. Wood is very common, and it looks like my Shapeoko XXL can even manage to handle aluminum. I didn’t buy a CNC machine to cut either of those materials. I’m sure I’ll find some excused to do some woodworking projects in the future, but I bought my machine to cut carbon fiber quadcopter frames!

These Router End Mills are ideal for plunge routing and producing precise contours – making them ideal for sign making and metal forming.

That last part is the scary part. Take lots of precautions. Wear a mask. Keep the garage door open, and point a big fan over your machine and out the door. Better yet, pick up the machine and take it out into the driveway!

Specialised software is used to send automated milling instructions or a ‘toolpath’ to the machine which then cuts away a design in your stock material.

Commonly referred to as Flat End Mills, square-end mills produce a sharp edge at the bottom of the slots and pockets of the workpiece.

Fish tail points prevent any splintering or breakout and will plunge directly into your material producing a flat surface.

I don’t know why, but I thought this would be a longer blog! I guess there’s not much to say. These are my feed rates. These are the bits I’m using. This is the carbon fiber I’m cutting. The cuts are clean. Done. Right?
