High Speed Steel Extended Twist Drill Bits 6.5mm Drill Dia. 160mm Length 4 Pcs 6.35mm to 8mm resulting in longer tool lifeDescription 1. Made of high speed steel. HSS(High Speed Steel) enables the drill body harder and can keep a longer drilling life. 2. With the twisted design, it can improve cutting accuracy by centering the tip. It can avoid displacement of the drill bit during work, and at the same time remove debris and particles faster and easier. 3. Suitable for processing non ferrous metals, such as copper and aluminum, and also suitable for hard plastics. When
