• Twist drills are made of high hardness, wear-resistant M42 cobalt.
• The addition of M35 cobalt improves the durability of the drill under high temperature environment and prolongs the service life.
• Suitable for drilling hard metals such as stainless steel, alloy steel, cast iron, etc., and can also quickly drill through soft materials such as wood and PVC.
• The double spiral edge design accelerates chip removal, avoids clogging and improves drilling efficiency.
• Wide for drilling concrete, walls, bricks, ceramic, wood, glass, tile, stainless steel and more; while drilling harder materials, Water or coolant is highly recommended
