Bernardo End Mill Sharpener EMG 30 Pro
The Bernardo End Mill Sharpener EMG 30 Pro is the tool for resharpening HSS and carbide end mills. It allows the processing of end mills with 2, 3, and 4 flutes, as well as 6-flute end mills from Ø 12 mm, with a diameter range between 12 and 30 mm. Compared to the basic version, the EMG 30 Pro integrates an additional station for sharpening external helices, increasing versatility and precision. The robust construction with anti-vibration rubber feet minimizes vibrations, while the rotor with precision ball bearings ensures smooth and consistent operation. Compact but powerful, with a 0.25 kW motor at 4400 rpm, it allows rapid adjustment of the relief angle from 0° to 5°. It comes with two CBN grinding wheels, a complete set of ER 40 collets (Ø 12–30 mm), and a collet holder.

Frequently asked questions
Is the EMG 30 Pro different from the EMG 30?
The Pro version adds advanced functionalities compared to the standard EMG 30 — typically greater positioning precision, improved guides, or extended capacity in terms of sharpenable geometries. Check specific differences in the technical table or by contacting Krollit. Both sharpen HSS end mills from Ø 12 to 30 mm with 2, 3, 4, and 6 flutes.
Does the EMG 30 Pro also sharpen carbide (HM/TCT) end mills?
With a CBN or diamond grinding wheel. The standard grinding wheel supplied is optimized for HSS end mills. For tungsten carbide end mills, a diamond or CBN grinding wheel is required — contact Krollit for the availability of the specific grinding wheel.
How many minutes does it take to sharpen a Ø 20 mm end mill?
A slightly worn Ø 20 mm 4-flute end mill takes 5–10 minutes. A very worn end mill can take 15–20 minutes. Operator experience significantly affects sharpening times and result quality.
Are replacement grinding wheels available?
Yes. Original Bernardo replacement grinding wheels for the EMG 30 Pro are available with 3–5 business days shipping.
Is assistance available?
Original spare parts available with 3–5 business days shipping. Customer support available in Italian.
