Carbide Straight Handle Type Inner Coolant Drill Bits

Solid Carbide Twist Inner Coolant Drill Bit For Cas Iron An inner-coolant drill is a type of cutting tool that is used for drilling holes in various materials, such as metal or plastic. It is designed to deliver coolant to the cutting edge of the drill bit, which helps to reduce the temperature of the cutting area and prolong the life of the tool. The basic design of an inner-coolant drill typically includes a central channel or "coolant hole" that runs through the center of the drill bit. Coolant is delivered through this channel and exits through small ports located near the tip of the bit. The coolant can be delivered at high pressure to help clear chips away from the cutting area, or at a lower pressure to provide a continuous flow of coolant to the cutting edge. The coolant used in inner-coolant drills is typically a water-soluble oil or a water-based fluid that contains additives to improve its lubricity and cooling properties. The coolant is usually delive…
