Size No. 16. Drilling range 5.3-38.5 mm. Dimensions: core hole DIN/EN 60423. With this robust tool, sheets can be centered, pre-drilled, reamed, and deburred in a single operation. The deeply ground spiral flute ensures absolute smooth operation and high cutting performance. In particular, non-breaking chips are cleanly removed, similar to a spiral drill. This reduces the formation of built-up edges and cold welding on the cutting edges. The cone facilitates retraction when drilling through sheets.
