Engraving bits solid carbide
Professional set of solid carbide graver
The high-quality graver have a more precise free and relief grinding as well as sharper blades compared to cheap versions from China. Thus the engraving bits achieve much more accurate engraving results.
Fine machining works only with high-quality graver
A graver with a font width of 0.1 – 0.5mm, for example, has a free grinding of 0.03 – 0.15mm. The free grinding is located behind the blade and avoids the graver from rubbing with the material behind the blade. If not the graver would make bad engraving results because the blade doesn’t come into action properly. Moreover, the engraving bit would wear quickly.
The smaller the engraving diameter the more you need a premium graver
Products from the far east reveal deficiencies especially when it comes to fine machining. Most of the graver in the price range of 2 – 5 Euro cannot make high-quality engravings since milling motors with a true running accuracy of 0.02-0.05mm totally neutralise the fine grinding. In this case, you can only use a graver of 1.2mm width or wider because you can choose the free angle wider than it was the case with a graver with a small font width.
