Review on ✈️ Bosch BL2751 Extra Length Aircraft: Unmatched Performance and Endurance by Ronnie Polk

Excellent Drill. I use it to drill some 9" deep holes in two panels of a very hard sideboard to insert some brass rods. The bit didn't play and there were no breaks. The black oxide coating adheres very well (Bosch typical). The only Negative is the ribbing of the bit, for a deep bore they don't go far enough to remove the moldboard well, even if they back off they are still too shallow as they have to come out almost entirely of every hole you drill .
