COUNTER SINK BIT: HSS 10-31.0MM 3 FLUTE MT2 TAPER

* This large three flute countersink is manufactured fron HSS-M2 * This offers durability and long service life for this cutter * Comes with MT2 shank to suit drilling machines Choosing the Right Countersink How to Choose the Right Size Countersink by Diameter A simple rule of thumb is to choose a countersink which is 50% larger than the diameter of the hole Countersink diameter = 1.5 x bolt size (hole) diameter Ex: For a 1/4-20 bolt, multiply the diameter (.250) x 1.5 = .375. This equates to a 3/8” countersink How to Choose The Right Size Countersink by Angle Angle is based on the screw or bolt type being used 82º is most common
