Compare two-flute carbide micro end mills in NES, DES and EES series. Choose from 25 model specifications, with cutting diameters from 0.1 to 0.9 mm, 4 mm shanks and 50 mm overall lengths. Send AXIMET your model list or part drawing for a quotation.
A micro end mill needs more than a diameter match. Cutting length, access to the feature and the selected series affect which model belongs on your purchase order. Compare the working end first, then check the shank and overall dimensions against your machine setup.
Compare the full-tool profile, cutting section and shank views alongside the model specifications. Use the series and model information with each image group when preparing your enquiry.

The series share a shank size and overall length, but they are not a single interchangeable size list. NES and DES have matching listed dimensions. EES has longer cutting sections at the same cutting diameters. Keep the series prefix attached to every line item.
| Series | Listed models | Cutting diameter D (mm) | Cutting length Lc (mm) | Selection detail |
|---|---|---|---|---|
| NES | 9 | 0.1–0.9 | 0.1–0.9 | Lc equals D in the listed models |
| DES | 9 | 0.1–0.9 | 0.1–0.9 | Same listed dimensions as NES; retain the DES series identity |
| EES | 7 | 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.8 | 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.6 | Lc equals 2D in the listed models |
For example, NES0052 and DES0052 both list a 0.5 mm cutting diameter and a 0.5 mm cutting length. EES0052 lists the same 0.5 mm cutting diameter with a 1.0 mm cutting length. That difference belongs in the selection decision even though the shank and overall length match.
Coating, carbide grade and workpiece requirements should be stated with the selected series in your enquiry. A shared diameter does not establish that two series have the same cutting behaviour or are suitable for the same application.
All dimensions below are in millimetres. D is cutting diameter, Lc is flute length, d is shank diameter and L is overall length. Each row identifies one model; select quantities by model rather than ordering only by diameter.

Use the part drawing to define what the cutter must reach and remove. For industrial purchasing, these details make a useful starting point for comparing a replacement tool, a sample requirement or a distributor assortment.
State the finished feature width, internal corner requirements and machining operation. Select the cutter diameter against the toolpath and part drawing. Micro end mills, micro drills and ball-nose cutters perform different work; similar diameters do not make them substitutes.
Give the required cutting depth and any wall or fixture that restricts access. Lc describes the cutting section. The 50 mm overall length includes the holding section and transition, so it is not a 50 mm cutting-depth rating.
Name the exact workpiece grade, hardness or condition, and the required surface finish. Keep electrode copper, tool steel and other machining requests separate. Material and coating selection need the actual application, not just a photograph of a similar cutter.
Include the machine, spindle-speed range, holder or collet, tool projection and coolant or air arrangement. Installed runout reflects the combined tool, holder and spindle setup. Describe how it will be checked during your trial rather than applying one general limit to every micro diameter.
Importers, cutting-tool distributors and technical buyers often need different information from the same product range. Build the enquiry around the customer’s feature and machine conditions so the model list supports a defined machining task.
For small milled details and narrow profiles, provide the feature drawing, dimensional requirement and intended toolpath. The diameter and cutting length need to fit the feature while leaving clearance for the non-cutting part of the tool.
Identify whether the workpiece is a mould material or an electrode material, together with its grade and condition. Include the local feature depth and finish requirement. Keep the material-specific selection separate from the decision to use a square-end micro cutter.
List demand by full model code and quantity. Keep NES, DES and EES separately identifiable in your assortment, including cases where the diameters match. This makes the requested size mix clear and avoids replacing a short cutting section with a longer one by name alone.
Review the production equipment alongside the geometry required for your micro end mill order. For NES, DES and EES models, the cutting section, transition and 4 mm shank need to remain consistent with the selected drawing and model specification.
For these two-flute tools, define the square-end profile and cutting length on the selected model drawing. The working edge must be reviewed at a scale that makes the micro cutting section visible.
Check where the cutting section meets the larger holding section. Relate this transition to the wall and fixture clearance on your part drawing; overall length alone does not describe usable reach.
Specify the required series and any coating requirement together. Keep a material-specific tool selection tied to the ordered model throughout the quotation and sample discussion.

Review the inspection equipment together with the acceptance requirements for your selected micro end mill. Cutting diameter, flute length, edge condition and installed runout require distinct checks; specify the dimensions, limits and records needed for your order.
Identify D, Lc, d and L, with the required tolerances and units. The listed 4 mm shank and 50 mm overall length do not replace the need to check the much smaller cutting section.
Define the edge and tip features to review under suitable magnification. Agree what constitutes an unacceptable defect before comparing samples or a production batch.
State the holder, tool projection, measurement position and method used for your assessment. A tool measurement and the runout of the complete installed assembly should not be treated as the same result.

Use one line for each series, model and quantity. For a trial order, describe the machining result you need to assess. For a repeat order, include the approved item or drawing revision so the enquiry identifies the same tool.
Example line item: NES0052 — D 0.5 mm, Lc 0.5 mm, d 4 mm, L 50 mm, two flutes. Add your quantity, workpiece and inspection requirements to make the enquiry specific.
Request price, order quantity, packing and lead time for the actual model mix. A single diameter range does not describe the commercial requirements of a multi-model order.
NES and DES each list nine cutting diameters from 0.1 to 0.9 mm in 0.1 mm increments. EES lists 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 and 0.8 mm. All listed models have two flutes, a 4 mm shank and a 50 mm overall length. Compare the series tables for the corresponding cutting lengths.
Do not select a substitute by diameter alone. NES and DES share the listed dimensions, but their series identities remain separate. EES has a longer listed cutting section at the matching diameters. Compare the full model, geometry, workpiece and specified material or coating requirements before approving a replacement.
Provide the feature depth, shoulder-clearance requirement and tool projection from the holder. Cutting length Lc describes the fluted working section; overall length L includes the rest of the tool. If your feature needs additional reach, send a drawing rather than treating the 50 mm overall length as an available cutting depth.
Describe the machine, holder or collet, tool projection, and the position and method used to assess runout. Include the acceptance limit required by your application. The complete assembly affects the result, so a shank measurement alone does not describe the cutting tip’s behaviour in the intended setup.
Record the full model, workpiece grade and condition, tool projection, holder, toolpath, spindle speed, feed, engagement and chip-removal method. Include photographs of the tool and feature where useful. Breakage has several possible causes; a broken-tip photograph alone does not establish the root cause or justify increasing a cutting parameter.
Send your model list or tool drawing, quantities by model, workpiece material and condition, machining task, and machine or holder details. Add dimensional or inspection requirements, packing preferences and destination. For a replacement enquiry, include the existing tool specification or approved drawing so AXIMET can review the same requirement.
Send AXIMET the full model codes and quantities, or share your part and tool drawings with the machining conditions. Include your cutting length, workpiece and inspection requirements so the enquiry covers more than diameter alone.
