Sharpening machines from Promash

Here are the five specialised OPTIgrind machines from Optimum for sharpening and deburring, with prices from €78 to €2,974.80. They sharpen at an angle, which is why they produce a symmetrical point that is hard to achieve by hand on a bench grinder.

OPTIgrind GQ-D13 sharpens drills from 3 to 13 mm with a diamond wheel and is the most affordable — €78. The GH 10 T comes with 11 ER 20 collets from Ø2 to Ø13 mm, and the GH 15 T — with ER 20 and ER 40 collets up to Ø30 mm. The GH 20T is a multifunctional machine with a 24-position head and fixtures for lathe tools, milling cutters and drills. The GB 250B is a brush deburring machine, 400 V.

How to choose? By the diameter of the drills and whether you also sharpen other tools. For knives and chisels, see the machines with a water system in sharpening machines and bench grinders.
