Who uses the CM 14 and for what
The Bernardo CM 14 is a dual sharpener: it reconditions both twist drills (like the DG 13 M) and shank end mills (like the EMG 30) in the Ø 4–14 mm range. For workshops that use both types of tools, it is the most economical solution compared to buying two separate sharpeners. Weighing 11 kg and operating at 230V, it can be placed on any workshop bench without installation. In Krollit's customers' workshops, it is used by small mechanical workshops with moderate drill and end mill consumption looking for an all-in-one solution.
Who is the Bernardo CM 14 for
| Profile | Compatibility | Reason |
|---|---|---|
| Passionate hobbyist | Ideal | 11 kg, 230V, dual function drills+end mills: the complete solution for those who want to recondition both types of tools in a single economical machine. |
| Small mechanical workshop | Ideal | Drills and end mills up to Ø 14 mm: covers the most used tool range in small workshops with a single sharpener. |
| Large industrial workshop | Adequate | For large volumes or diameters over 14 mm, consider DG 32 Pro or EMG 30 separately for superior performance. |
Not suitable for: tools over Ø 14 mm; taps (consider STG 20); large carbide end mills.

Frequently asked questions
Does the CM 14 sharpen both drills and end mills with the same machine?
Yes. The CM 14 has a universal clamping system that works for both twist drills and shank end mills in the Ø 4–14 mm range. The sharpening configuration changes based on the tool: for drills, the standard angle is used; for end mills, the specific geometry of the front cutting edges is set. The Italian manual explains the procedure for both.
What is the difference between CM 14 and DG 13 M?
The DG 13 M sharpens only drill bits up to Ø 13 mm with a fixed angle. The CM 14 sharpens both drills and end mills up to Ø 14 mm with an adjustable angle of −30°/+30°. The CM 14 is more versatile; the DG 13 M is simpler and specialized for drills only.
Does the CM 14 also sharpen carbide (hard metal) drills?
Yes, with the correct grinding wheel. For tungsten carbide drills, diamond or CBN grinding wheels are used, which are not always included as standard. Check with Krollit for the included grinding wheel and the availability of grinding wheels for carbide.
Are replacement grinding wheels available?
Yes. Original Bernardo replacement grinding wheels available with 3–5 working days shipping.
Is training required to use the CM 14?
For drill bits, the CM 14 is relatively intuitive thanks to its guide system. For end mills, correct setting of the cutting edges requires more practice. It is advisable to start with already worn tools to gain confidence before sharpening tools in good condition.
