Product description

Ball Nose Carbide End Mill NKN (standard length) is a ball nose end mill series used for 3D surfacing, mould finishing and curved forms. A carbide body allows a higher cutting speed and a longer tool life than an HSS tool.

This family contains 19 sizes; the cutting diameter spans 1 – 20 mm, the shank diameter 4 – 20 mm, the flute length 2 – 24 mm, the overall length 50 – 100 mm, the corner radius 0.5 – 10 mm. The price range is $13.65 – $318.50 (excl. VAT).

Choosing within the family: Within the same geometry this series offers the widest choice of sizes (19 sizes).

Application note: On a ball nose the cutting speed falls to zero towards the centre. Tilting the tool relative to the surface so that centre contact is avoided is therefore preferred; surface finish and tool life both improve.

Every order code in the table below can be added straight to the cart. The meaning of the column abbreviations is explained in the dimension code guide. Spindle speed and feed can be worked out with the cutting parameter calculator.

Frequently asked questions

Which sizes does the NKN series cover?

This family contains 19 sizes; the cutting diameter spans 1 – 20 mm. The full list is in the table above; every row is a separate order code and can be added straight to the cart.

Is D1 or D2 the relevant dimension when ordering?

Both are considered together. D1 is the cutting diameter and sets the width of the slot to be cut. D2 is the shank diameter and states what the holder or collet has to grip. On small diameter cutters the shank is usually thicker than the cutting diameter, so the row whose D2 matches the available collet is chosen.

Is this 2 flute tool suitable for full slotting?

Yes. A 2 flute tool is suitable for full slotting; the gullet offers enough volume for chip evacuation.

How long does delivery take when an item is not in stock?

For sizes shown as "On order" the delivery time is confirmed with the order. Urgent requirements can be raised through the quote form or via WhatsApp.
