As these drills are for position-controlled drilling jobs on hard brittle materials, they are made of PCD, which is a type of sintered diamond that has superb abrasion resistance.<\/p>

While the simultaneously released PCD multi-angle drills alone can handle high-precision machining jobs, the additional use of PCD point drills will improve the hole-positioning precision and allow for more stable job execution.<\/p>

The standard edge diameters are between \u03c60.3 and \u03c63.0 mm.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
