One query instead of a thousand rows in a list
You don’t buy milling cutters by catalog number, but by application: The material determines the cutting material, the machine determines the shank, and the quantity determines the design—fixed-tooth or with indexable inserts. This guide addresses exactly these questions. We keep the most common edge milling cutters in stock here in the Black Forest; for everything else, we order directly for you from over 4,000 catalog tools—with a response within one business day. For those who prefer reading to clicking: Here’s the knowledge behind the questions.
Here's how to find the radius of your edge
A rounding cutter is selected based on its radius, not its diameter. When replicating a design, the quickest way to measure the existing rounding is with a radius gauge: Place the edge into the corner; the arc that fits snugly without a gap is your R. A printable template with the standard radii from R 2 to R 12.7 is available in the guide. For new workpieces, the rule of thumb is: R 2 to R 4 creates a noticeable break in the edge, R 6 to R 8 creates a visible rounding, and starting at R 10, the rounding becomes a design element. The stock selection of radius cutters covers R 2 to R 12.7; larger radii are available from the catalog.
Chamfer angle: 45° is the standard, not a requirement
The 45° bevel is the most common—two mitered pieces form a right angle, which is why we keep it in stock. In addition, 15°, 22.5°, and 30° each have their specific uses: 15° for a fine edge rounding that adds almost no material, 22.5° for octagonal cabinet bodies, and 30° for a visible bevel on fronts and tops. Important when purchasing: The angle is fixed in the tool—unlike the depth, it cannot be adjusted. If you use it frequently, the indexable insert version is a better choice: simply rotate the cutting edge instead of sending it to a sharpening service.
Groove width: one cutter, one pass
A clean slot in a single pass: the cutter diameter equals the slot width. Theslot back panels and system holes is the classic choice, along with 6, 10, and 12 mm. Running the cutter twice with a narrower cutter is possible in a pinch—but it takes time, and the width rarely matches to the nearest tenth. For production runs, it’s worth considering indexable-insert groove cutters: same slot, interchangeable cutting edges. And for 12 mm, it’s worth checking whether you really need 12.0 mm or the inch-based 12.7 mm—the difference determines whether the bottom will rattle.
shank or 12 mm shank – and when the tool should be placed in the table
The shank collet the collet : Handheld routers typically use an 8 mm shank, while bench routers use a 12 mm shank. Many tools are available in both versions—the advisor will show you the difference right in the results. If in doubt, a reducer sleeve connects theshank the 12 mm collet. The second rule is based on physics: Large diameters belong on the table, not for freehand use—flattening cutters and gluing profiles are used in a stationary setup, with the workpiece guided.
HW, VHM, or DP: The cutting tool material is chosen based on the workpiece material
Carbide-tipped (HW) is the standard for solid wood—tough enough for knots, sharp enough for clean edges. solid carbide VHM) really shines with its rigidity when working with laminated panels: spiral and finishing cutters with a pulling cut leave melamine edges free of tear-outs. Diamond-tipped (DP) tools are the solution for abrasive materials—HPL, compact, and mineral-based panels. The additional cost may seem daunting at first; however, when calculated over the tool’s service life, DP is usually the most cost-effective option per meter of edge. For acrylic glass and aluminum, there are dedicated single- and double-fluted cutters with polished chip spaces.
When Are Indexable Inserts Cost-Effective?
The math is simple: A fixed-tooth milling cutter has to be sent out for regrinding—each cycle involves the cost of replacement, shipping, and downtime. With the indexable-insert version, you turn the cutting edge in the shop: four edges, then a new insert for just a few euros. Whether the extra cost is worth it depends on your hourly rate and how often the tool is used—as a rule of thumb: daily use almost always pays off, while a tool used only on weekends almost never does. The hourly rate calculator knows your actual hourly rate.

Rotational Speed by Diameter
The larger the milling cutter, the slower it must rotate—otherwise, the cutting edge on the outside will rotate faster than the tool can handle. The guidelines for the maximum speed are:
| Cutter Diameter | Max. speed |
|---|---|
| 1–24 mm | approx. 28,000 rpm |
| 25–30 mm | approx. 24,000 rpm |
| 31–50 mm | approx. 18,000 rpm |
| 51–67 mm | approx. 16,000 rpm |
| 68–90 mm | approx. 12,000 rpm |
Drill bits should be run at significantly lower speeds: up to 9 mm in diameter, a maximum of 8,000 rpm; for diameters of 10 mm and larger, no more than 4,000 rpm. When clamping the bit, ensure shank and free of grease and is inserted into the collet at least up to the mark—the minimum clamping length is specified by DIN EN 847-2. These are approximate values based on the manufacturer’s specifications in the catalog; the markings on your tool and your machine’s instructions always take precedence.
Replacement Parts Instead of Buying New
A milling cutter is rarely at the end of its service life simply because one part is worn out. Indexable inserts are available in all standard lengths from 7.5 to 60 mm, and guide bearings from Ø 8 to Ø 47—including plastic-coated versions for delicate surfaces. If you know your milling cutter’s part number, the advisor will directly match you with the right parts; if you only know the dimensions, you can find what you need by entering the size. This typically saves you two-thirds compared to buying a new one.

What we are asked about
Which shank my machine—8 or 12 mm?
Hand routers typically have an 8-mm shank, while bench routers have a 12-mm shank. Many tools are available in both versions—the consultant demonstrates the difference directly using the finished result. If necessary, a reducer sleeve can connect theshank the 12-mm collet.
What do HW, VHM, and DP mean when referring to milling cutters?
HW is cemented carbide on a steel body—the standard for solid wood. VHM stands for solid carbide; it offers greater rigidity and a finer cut, and is typically used in spiral and finishing cutters. DP stands for diamond: when used on HPL, compact, and abrasive panels, it lasts many times longer.
How can I determine the radius of an existing edge?
Using a radius gauge: Place the edge against the corner—the arc that fits snugly without a gap is your R. A printable template with radii ranging from R 2 to R 12.7 is available in the guide.
When is the indexable insert version a good choice?
As soon as regrinding causes downtime: Turning the cutter takes minutes, while the sharpening service takes days. Multiply the hourly rate by the changeover time per sharpening cycle—this calculation is included in the consultant’s report for every indexable insert recommendation.
Do you also order tools that aren't in stock?
Yes. We keep the most common edge cutters in stock here in the Black Forest, and we’ll order everything else for you from our catalog of over 4,000 tools—one package, one invoice, and a response within one business day.
What is the maximum speed my milling cutter can rotate at?
The larger the diameter, the slower the speed: up to 24 mm, about 28,000 rpm; for 31–50 mm, 18,000 rpm; and for 68 mm and larger, only 12,000 rpm. Drill bits rotate significantly slower. The complete table is at the top of this page—the marking on the tool always takes precedence.
Are there replacement parts for my old milling cutter?
Often, yes: We collets indexable inserts, guide bearings, screws, and collets across our entire product line. Just enter your milling cutter’s part number into the advisor—it will list the compatible parts, including those for discontinued models, while supplies last.
