SP802 Super Cutter

Though SP802 is far superior than many drill bits, its cutting flutes gets blunt after removing 20 – 30 spotwelds. It can then be sharpened by S1000K Roken Sharpener to restore its original performance and cut another 20-30 spotwelds of AHSS. It can be resharpened as many times as long as there is cutting material

 The SP802 must be used with a slow RPM air drill to prevent burnt cutting edge due to excessive friction. The Astro Low RPM air drill is tested and proven to provide the best effectiveness to the system.
