Ruko Tube & Sheet Titanium Drills With Spilt Points

Ruko Tube and Sheet Titanium Drills with Split Point ZR1010T

Ruko tube & sheet drill flutes are ground using CBN (cubical boron nitride) ... So what?, you might ask. Its far harder than corundum and silicium carbide and therefore the user gets a sharper cutting edge without burrs. The cone shape enables easier withdrawal of the tool from the piece being worked. This is the perfect drill for those working with sheet metal such as electricians, mechanical engineers, workers in the fields of aviation, heating, automotive etc.
