Set de burghie pentru metal DeWALT - HSS-E, DT4927-QZ, 10 buc.
The DeWALT DT4927-QZ metal drill bit set from DeWALT is designed for precise and efficient drilling of hard and high-alloy metals. Made from high-quality HSS-E high-speed steel with 5% cobalt content, these drill bits offer exceptional wear resistance and high-temperature durability. The golden iron oxide coating prevents overheating and significantly extends the tool's service life. The drill bit design features a No-Walk tip with a 135° angle, which ensures accurate centering without slipping and allows drilling without pre-centering. The gradually increasing core thickness towards the shank provides greater strength against breakage, while the three-sided cylindrical shank prevents the drill bit from slipping in the chuck under heavy loads.
