Choosing a ball nose end mill
Start with the radius you need to cut, because the ball radius is half the cutter diameter. Then choose the flute count and length: 2 flute ball nose slot drills can plunge and slot, and 4 flute cutters are listed for profiling and finishing. Choose a coating to suit the material (TiAlN, AlCrN, CrN and TiSiN are all listed in this range), and use a long reach cutter only where the depth needs it, because more overhang reduces rigidity and calls for lower speeds and feeds. Check the shank style against your toolholder before ordering. Carbide cutters suit higher speeds and harder materials, while HSS and cobalt cutters are a lower cost choice for general work.
Always check the data sheet. Confirm the cutter diameter, length, shank and recommended speeds and feeds before use.

Ball nose end mill FAQs
When should I use a ball nose end mill instead of a square end mill?
Use a ball nose for curved surfaces, 3D contouring, fillets and finishing profiled shapes. A square end mill suits flat floors and square shoulders. See our square end mills.
What flute count should I choose?
We list 2, 3 and 4 flute ball nose cutters. Two flute cutters give more chip room and can plunge and slot, and 4 flute cutters are used for profiling and finishing. Check the product page and your material before choosing.
What do the Sutton E-series codes mean?
The E number identifies the cutter series, for example E602 is a 2 flute carbide ball nose slot drill and E607 is a 4 flute TiAlN carbide ball nose end mill. The title lists the flutes, material, coating and length style for each series.
What sizes do you list?
Metric cutting tips from 0.2mm to 25mm across the Sutton range, and Bordo slot drills from 3 to 30mm and 1/8 to 2 inch. Sizes vary by series, so check the variants on each product.
Do you list imperial ball nose cutters?
Yes. We list the Sutton E314 in 1/8 and 1/4 inch and Bordo imperial HSS ball nose slot drills from 1/8 to 2 inch.
What is a long reach ball nose cutter for?
A long reach cutter reaches deeper into pockets and cavities than a regular length cutter. Extra overhang reduces rigidity, so reduce speeds and feeds to suit.
