CORMAK DG20 is an advanced drill bit grinder-sharpener designed for professional use in industrial plants, tool workshops and maintenance departments. It enables precise sharpening of drill bits made of high-speed steel (HSS) and cobalt alloys in the range of ø2–20 mm. Equipped with a durable CBN grinding wheel, a robust housing and a complete set of ER collets, it guarantees high precision and repeatability of the grinding process.

Main advantages of the machine

• Wide diameter range: sharpening of drill bits from ø2 to ø20 mm.
• Adjustable point angle: 90°–135° – allows matching the drill geometry to specific materials and applications.
• CBN (borazon) grinding wheel: high durability, ideal for HSS and cobalt drills, ensures excellent sharpening results.
• High rotation speed: the 4,800 rpm motor enables smooth and fast grinding.
• No specialist training required: intuitive drill guidance ensures accurate results without prior experience.
• Compact and lightweight design: with a total weight of only 11 kg, it is ideal for mobile or small workspaces.
• Complete equipment: includes ER20 and ER25 collets, two clamping holders – ready for immediate use.

Design and technology

The CORMAK DG20 Drill Bit Grinder-Sharpener is manufactured using high-quality components to ensure durability and precision. Its rigid body structure eliminates vibration, improving grinding accuracy. The CBN grinding wheel is designed for heavy-duty use, providing even sharpening results and long service life. The optimised guidance and collet system ensure ergonomic and repeatable positioning, while the 180 W motor provides sufficient power for efficient tool regeneration.
