The characteristics of the single flute chamfering cutters are similar to those of the deburring tools "with hole". They do vary on the following points: Greater countersinking capacity, from the point to the outside diameter (up to dia. 30 mm) and simultaneous drilling and countersinking on thin elements (laminates, aluminum, wood). Constant finish-grind profile makes it possible to obtain many easy regrinds: a mere touch of the grinder to the tooth is sufficient. We recommend lubricating.
