Roofing drill Ø 5.70 mm L66 Profi

Right-hand twist drill with a straight shank. Made from high-speed steel (HSS). For fixing holes in roofing sheets and for drilling carbon, alloy and structural steels and cast iron.

Profi drills centre easily, usually without centre-punching. They last longer and can drill holes up to five times faster.

The special split point helps the drill centre itself and resist wandering. A centre-punch mark is rarely needed. 

Profi drills bite readily and produce more accurate holes. They can last up to three times as long and reduce drilling time for the home user by a factor of up to five. These drills receive an additional protective treatment to improve corrosion resistance.
