Product description
The Square Carbide End Mill SDN (standard length) series belongs to the square end mill family and is preferred for slotting, pocketing and surfaces that require a sharp corner. A carbide body allows a higher cutting speed and a longer tool life than an HSS tool.
This family contains 15 sizes; the cutting diameter spans 1 – 20 mm, the shank diameter 4 – 20 mm, the flute length 3 – 38 mm, the overall length 50 – 92 mm. The price range is $15.02 – $340.34 (excl. VAT).
Choosing within the family: Among the series of the same geometry it stands at 15 sizes and an entry price of $15.02.
Application note: A square end leaves a sharp corner, and that corner is the weakest point of the cutting edge. Where the design does not require a sharp corner, a corner radius tool lasts noticeably longer.
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 SDN series cover?
This family contains 15 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 4 flute tool suitable for full slotting?
On a 4 flute tool the chip gullet is narrow; in full slotting (ae = D1) the gullet can pack and break the tool. A 2–3 flute tool or a trochoidal strategy (ae ≤ 0.1 × D) is preferred for full slots.
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.
