30xD internal coolant deep hole drills

The 30xD internal coolant deep hole drill is a tool specially used for processing deep holes with a depth-to-diameter ratio of 30 times. The following is a detailed introduction about it:

1. Structural features

- Internal coolant channel design: It has an internal coolant channel. The coolant can enter from the rear end of the tool holder, pass through the inside of the tool, and reach the cutting area directly. It can take away the heat generated by cutting in time, reduce the temperature of the tool and workpiece, reduce tool wear, and improve processing accuracy and tool life.

- Special cutting edge design: The cutting edge is carefully ground and optimized, with high sharpness and cutting performance, which can effectively cut into the workpiece, reduce cutting force, and improve processing efficiency and hole processing quality.

- High-strength material manufacturing: It is usually made of high-strength and high-hardness materials such as cemented carbide to withstand the high cutting force and harsh working environment in deep hole processing. Some high-end products will also use special coating technology to further improve the wear resistance and cutting performance of the tool.

2. Working Principle

- During the machining process, the 30x diameter internal cooling deep hole drill is installed on the machine tool spindle. As the spindle rotates and feeds, the drill gradually cuts into the workpiece. At the same time, the coolant is transported to the cutting area through the channel inside the tool to cool and lubricate the tool and workpiece, and flush the chips away and discharge them through the gap between the tool and the workpiece.

3. Application Advantages

- High-precision machining: It can ensure that in the 30x diameter deep hole machining, the dimensional accuracy, shape accuracy and surface quality of the hole reach a high level, meeting the machining requirements of parts with high requirements for deep hole machining accuracy.

- Efficient machining: Good cooling and lubrication effects enable the tool to be machined at a higher cutting speed, improving machining efficiency and shortening machining time.

- Extended tool life: Effective cooling reduces the cutting temperature of the tool, reduces thermal damage and wear of the tool, extends the tool life and reduces machining costs.

4. Application fields

- Widely used in various parts that require deep hole processing in industries such as machinery manufacturing, automobile manufacturing, aerospace, mold manufacturing, energy equipment, etc., such as deep holes on engine blocks, deep holes in hydraulic cylinder barrels, deep holes in molds, etc., especially suitable for processing occasions with high requirements for hole depth and precision.

5. Product examples

- CrazyDrill Cool XL series: The drilling diameter range is 1.0mm to 6.0mm, and the drilling depth can reach 30 times the diameter. All drill bits are coated, and the coolant can run through the entire shank, with sharp double edges after grinding.

- CrazyDrill Cool SST-Inox drill bit: It can drill holes with a diameter range of 1.0mm to 6.35mm, and the drilling depth can reach 30 times the diameter. It is suitable for processing stainless steel materials, heat-resistant materials and cobalt-chromium alloy materials.

In short, the 30x diameter internal cooling deep hole drill plays an indispensable role in the modern manufacturing industry with its unique structure and significant application advantages. It not only improves production efficiency and processing quality, but also effectively reduces costs. It is an important tool in the field of deep hole processing.
