Through Coolant Drills, Size: 9mm

Product Details

Through-Coolant Drills are specialized drill bits designed to deliver coolant directly to the cutting edge along the entire length of the drill bit. Unlike traditional drills, which may only use external or internal coolant delivery systems, through-coolant drills are specifically engineered to allow coolant to pass all the way through the tool, ensuring optimal cooling, lubrication, and chip removal during drilling. These drills are particularly valuable in high-performance and precision drilling applications, especially in industries that require deep hole drilling, hard materials, and high-speed cutting. Key Features of Through-Coolant Drills: Internal Coolant Path: Through-coolant drills have an integrated passage within the drill bit that allows coolant to travel through the entire length of the bit. The coolant exits at the cutting edge, keeping the bit and the workpiece cool, while also flushing chips out of the hole. Improved Heat Management: Cooling the cutting edge reduces heat generation and prevents overheating of the tool and material. Overheating can cause premature tool wear, poor hole quality, and material deformation, so through-coolant systems are essential for maintaining consistent performance. Enhanced Lubrication: The coolant reduces friction between the drill bit and the workpiece, resulting in smoother drilling, less wear on the tool, and the ability to use higher feed rates and cutting speeds. Better Chip Removal: The coolant helps clear chips from the hole, preventing them from getting stuck between the drill bit and the material. This helps reduce the risk of tool jamming, ensures a cleaner hole, and allows for higher cutting performance. Precision in Deep Hole Drilling: When drilling deep holes, maintaining proper cooling and chip removal is crucial. Through-coolant drills are especially effective for deep-hole drilling applications, as the coolant can flow through the entire drill bit, reaching deep into the hole. Advantages of Through-Coolant Drills: Extended Tool Life: The cooling effect significantly reduces heat stress on the drill bit, preventing premature wear, thermal expansion, or even tool failure, which results in extended tool life. Increased Drilling Speed: With the ability to maintain lower temperatures during the drilling process, operators can increase cutting speeds and feed rates, making the drilling process faster without sacrificing hole quality or tool life. Improved Hole Quality: By preventing overheating and ensuring effective chip removal, through-coolant drills produce high-quality holes with minimal burrs and surface imperfections. Reduced Risk of Material Damage: Certain materials, such as heat-sensitive alloys (e.g., titanium), can be damaged if the drilling process generates too much heat. Through-coolant drills mitigate this risk by keeping the material cool, preserving its integrity. Consistency in Deep-Hole Drilling: Deep-hole drilling generates more heat and has a higher risk of chip buildup. The through-coolant system ensures that cooling and chip flushing remain effective throughout the entire depth of the hole, leading to more consistent results.
