Glossary (NA/EU Aligned)
- HV: Vickers Hardness (standard for diamond grit; higher = harder).
** MRR: Material Removal Rate (tested on EU C20 concrete, common in residential builds).
*** N: Newton (impact force; aligned with NA workshop/EU quarry safety norms).
**** HRC: Rockwell Hardness C Scale (compatible with NA/EU metal matrix blades).
***** GPa: Gigapascal (compressive strength; meets NA deep mining/EU tunneling demands).
****** Note: NA uses pounds (lb) for small quantities; EU uses kilograms (kg) per standard.
