12 best fly cutter for milling machine

A fly cutter is a cutting tool used in milling machines for machining surfaces. It is a single-pointed tool that attaches to the spindle of a milling machine. Here are some key points about fly cutters:

  1. Design and Construction:

    • Fly cutters typically consist of a single-point cutting tool (usually brazed carbide or high-speed steel) mounted on the end of a spindle.
    • The cutting tool can have various shapes, such as a simple round or square shape.
  2. Operation:

    • The fly cutter is rotated at high speeds by the milling machine spindle.
    • The cutting tool engages with the workpiece, removing material in a single pass.
    • The machined surface is determined by the shape of the cutting tool and the feed rate of the workpiece.
  3. Applications:

    • Fly cutters are often used for facing operations, where a flat surface needs to be created on the workpiece.
    • They can also be used for creating large, flat surfaces more efficiently than other milling tools.
  4. Advantages:

    • Simple design and easy to set up.
    • Cost-effective compared to some other milling tools.
    • Can achieve a good surface finish on the workpiece.
  5. Considerations:

    • The size of the fly cutter and the cutting tool geometry need to be chosen based on the specific machining requirements.
    • Proper speeds and feeds must be selected to ensure efficient material removal without causing tool wear.

In the context of the products you mentioned (Hole Saw Sets, Hole Saws Accessories, Power Drill Parts Accessories, Power Tool Parts Accessories, Power Hand Tools, Tools Home Improvement), the fly cutter is not directly related. Fly cutters are more commonly associated with milling operations, while the mentioned products are related to drilling, hole sawing, and power tools.

If you have specific questions about hole saws or power tool accessories, feel free to ask for information on those topics.

User questions & answers

Question: Can they bore cast iron
Answer: Determine the diameter and depth of cut, then do a search on the web, there are many good feed and speed charts available
Question: what would be a good RPM to run at for aluminium
Answer: I have used these fly cutter in my mill up to 1500 rpm. Good cutting around 900 rpm for aluminum. slower for steel.
Question: What is the maximum RPM for these cutters
Answer: With the stock bit it's about 70mm on the large cutter. But with a larger bit I'm cutting 120mm (5") on wood. Would not recommend very large diameters for metal.
Question: whats largest diameter cut of this set
Answer: no I.D. on the edge finder. case has mitutoyo america sticker on it. works fine no problem with it.

User questions & answers

Question: Can this be used to cut hard woods witthout burning the wood
Answer: As others have have stated it really depends on a lot of things, this is however more of a face mill it's not intended to take deep fast cuts, if you need to go deep use a conventional roughing end mill and use this for your final passes to get a nice clean finish. I've used mine on titanium and 7075 aluminum and it has produced a very nice smooth finish on the material.
Question: How many thousandths cut (per pass) can one take when using this tool on various metals
Answer: Look up ‘speeds and feeds’. Google that phrase, you’ll find what you need. Varies greatly with what you’re cutting, depth of cut, lubrication, rigidity of machine and workholding.
Question: What rpms have people been running this at? i have found suggestions on pm ranging from 250, to 2200... makes no sense
Answer: This is Standard R8 Shank ( Bridgeport Shank); which means the smaller end is 0.949" and larger end if is 1.25"; Shank length is 4"; drawbar thread is 7/16-20. Thanks.
Question: What is the shank diameter
Answer: My first answer is 7/16 in. I have a set of Irwin tap chucks that grab the square shank .. another brand of tap has a 3/8 inch .. perhaps a small crescent wrench

Accusize Straight Shank Carbide Indexable End Mill

The 3/4" straight shank indexable end mills are for general machining work. The triangle carbide TPG inserts help you save time and money. When a cutting edge becomes dull, you just need to rotate the insert in the holder to use the sharp edge. When you buy the replacement inserts, be noted that the larger nose angles and larger tip radii enable a stronger cutting edge, but they result in increased vibration and a rougher finish. Beyond, be noted that the listing has our recommended cutting speed of the indexable shell milling cutters with straight shanks.

  • Comes with TPG inserts installed
  • Uses standard triangular inserts.
  • Positive rake 90°, right-hand cut.

**Please note that we keep upgrading the products without further notification. Sometimes you will receive the products with Tin coated carbide turning milling TPG inserts. The coated inserts last longer and can run at faster speeds than uncoated ones.
