* Testing parameters core drill: dia. 100 x 2 mm, 24 x 3,5 x 10 mm

** Testing parameters circular saw: dia. 390 x 2,2 mm, 40 x 3,2 x 10 mm

¹ can also be sintered at 820 °C in case of need, but then it requires higher pressure and a bit more holding time

² with slight wear protection; suitable for abrasive concrete and non-abrasive asphalt

³ backing powder with wear protection for asphalt and similar abrasive applications
