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 delivered to the drill bit through a separate system that includes a pump, filter, and coolant reservoir.

When an inner-coolant drill is used, the coolant is delivered to the cutting area through the central channel in the drill bit. As the drill penetrates the material, the coolant helps to lubricate the cutting edge and reduce the temperature of the drill bit. This helps to prevent overheating and prolong the life of the tool. Additionally, the coolant helps to clear chips away from the cutting area, which can improve the quality of the drilled hole and reduce the risk of damage to the tool or workpiece

There are several types of Inner-coolant Drills available, each designed for specific drilling applications. Some common types of inner-coolant drills include:

Standard inner-coolant drills: These are the most basic type of inner-coolant drills and are designed for general-purpose drilling in a range of materials.
High-performance inner-coolant drills: These are designed for high-speed drilling in difficult materials, such as hardened steels or titanium alloys.
Deep-hole inner-coolant drills: These are designed for drilling deep holes in materials and typically have a longer flute length and more coolant outlets to ensure proper cooling and chip evacuation.
Gun drills: These are specialized inner-coolant drills that are designed for drilling deep, straight holes with high accuracy and finish quality. They typically have a single cutting edge and require a separate guide bushing to maintain alignment during drilling.
Indexable inner-coolant drills: These drills use replaceable carbide or ceramic inserts to reduce tooling costs and allow for easy replacement of damaged or worn cutting edges.
Micro-inner-coolant drills: These are extremely small diameter drills designed for drilling small, precise holes in materials such as circuit boards, electronics, and medical devices.

The specific type of inner-coolant drill that is best for a particular application will depend on the material being drilled, the size and depth of the hole, the required finish quality, and other factors
