These ten G3 drill bits with a diameter of 7 mm are designed for drilling different types of metal. Their HSS steel has been reinforced with a multi-layer TiALN coating capable of regulating the temperature of your drill bit, which prevents it from heating up and extends its service life. The ability to keep these accessories for longer gives them great value for money. The recognised strength of the HSS steel also gives high-quality drill bits. The Diager models are suitable for drilling alloyed and unalloyed steel up to a resistance of 1100 N/mm². Materials such as cast iron or aluminium will no longer resist you. By reducing friction, the TiALN coating also reduces the hazards of drilling, improving the cutting speed of your device and ease of use. In fact, comfort is the keyword of Diager's G3 drill bits. Their cross sharpening DIN 1412 C shape and S-type propeller ensure high stability when you start your device. They provide more precision during your drilling, making these drill bits ideal for a neat result! With these two HSS drill bits, Diager is aimed at beginners and experienced DIYers as well as craftsmen.
