• Size - Working Diameter: 3.2mm; Working Length: 38mm / 1.5"; Shank Diameter: 3.2mm; Total Length: 65mm / 2.56". The reduced shank can ce used with all drill presses and most power tools in the market.
• Material - High speed steel M2, resists corrosion, ensures outstanding durability, sharpness and capability, reduces the friction and runs cooler. Premium gold titanium and black nitride dual coating can apply lubricant better for smoother drilling and is more durable and corrosion resistant than the regular black surface.
• Tri-flatted Shank - 135-degree penetrates hard material without a hole and produces small chips to reduce clogging. Unique round shank locks onto chuck for portable drilling. Special design drills tough, high-tensile materials.
• Application - Reduced shank drill is used for drilling through hard materials such as stainless steel, alloy steel, cast iron, aluminum, copper, malleable iron, brass, wood, plastic, acrylic, nylon, ABS, and other metals commonly encountered in machining applications and personal projects.
• Note - Use proper speed, pressure, and heat control when using these drill bits to maintain efficiency. In the drilling process, the appropriate use of cutting fluid or oil for cooling and lubrication, to extend the service life of the drill.
