Đặc trưng

• High Speed Steel (HSS) Standard Straight Sharp Blade Drill.
• Cutting Proficiency: The tip is cross-thinned, so the cutting is quick, and the sharpness and efficiency are excellent.
• Not only general steel but also stainless steel has the same cutting ability as cobalt drill.
• Hole Diameter Accuracy: Maintains a high accuracy close to the outer diameter of the drill by having a special flat blade at the tip of two cutting edges to keep the cutting amount constant.
• Durability: A disadvantage of ordinary drills is that the tip chisel (edge) is hard to cut, but this drill has a special flat blade with an obtuse cutting angle and a sharp edge, which makes it slow to cut. (2 pcs)
