Who uses the DG 13 M and for what
The Bernardo DG 13 M sharpener restores worn twist drills in the Ø 2–13 mm range. In a machine shop that drills regularly, drill bits are among the most frequent consumables: a Ø 10 mm HSS drill bit costs 3–8 euros; sharpening it with the DG 13 M takes 20–40 seconds. At 8 kg and single-phase 230V, it can be installed on any workbench without additional equipment. In Krollit's customers' workshops, it is used by mechanical workshops, metal fabricators, and maintenance shops.

Frequently Asked Questions
What is the difference between DG 13 M and other Bernardo drill bit sharpeners?
The Bernardo drill bit range covers: DG 13 M (Ø 2–13 mm, 8 kg), DG 13 MD (Ø 2–13 mm with thinning, 8.1 kg), DG 20 M (Ø 2–20 mm with CBN wheel, 8.6 kg), DG 32 Pro (Ø 2–32 mm, 32 kg), DG 32 MD (Ø 12–32 mm with thinning, 30 kg). The choice depends on the maximum diameter of the drill bits used in the workshop.
Does the DG 13 M sharpen carbide drill bits?
With the standard grinding wheel included, the DG 13 M is optimized for HSS drill bits. For tungsten carbide drill bits, a diamond grinding wheel is recommended. Contact Krollit for the specific grinding wheel.
How long does it take to sharpen a Ø 10 mm drill bit?
With the DG 13 M, a slightly worn Ø 10 mm HSS drill bit takes 20–40 seconds. A very worn drill bit may take 1–2 minutes. The consistency of the result increases with operator practice.
Are replacement grinding wheels available?
Yes. Original Bernardo replacement grinding wheels are available with 3–5 working days shipping.
Is specific training required to use it?
Bernardo drill bit sharpeners have guidance systems that automatically position the drill bit at the correct angle. The operator only needs to insert the drill bit into the holder and advance it against the grinding wheel. Learning takes 5–10 minutes of practice.
