DIN338 HSS Twist Drill Bit Fully Ground Or TiN Coated

Functions For HSS Twist Drill:

HSS twist drills are primarily used for drilling holes in metal surfaces or workpieces. They are suitable for various metal materials such as steel, aluminum, as well as plastics and wood.

Usage For HSS Twist Drill:

1. Select the correct drill bit size: Choose the appropriate HSS twist drill based on the desired hole diameter and material type. Ensure that the selected drill bit is suitable for the required hole size.

2. Install the drill bit: Insert the drill bit into the drill chuck or drill press spindle, ensuring it is securely and correctly installed.

3. Cooling and lubrication: Use cutting fluid or lubricating oil during the drilling process to reduce friction and heat, prolonging the drill bit's lifespan.

4. Proper speed and feed rate: Select the appropriate speed and feed rate based on the material type and hole diameter. Typically, harder materials require lower speeds and smaller feed rates.

5. Maintain a stable posture: Maintain a stable posture during drilling to ensure accurate hole diameter and prevent drill bit damage.

Precautions For HSS Twist Drill:

1. Safety first: When using HSS twist drills, always wear appropriate personal protective equipment such as safety glasses and gloves.

2. Avoid excessive pressure: Avoid applying excessive pressure to prevent damage to the drill bit or workpiece. Apply the appropriate pressure to ensure the drill bit cuts steadily.

3. Regularly inspect drill bits: Regularly check the wear of the drill bit and promptly replace damaged or severely worn drill bits to ensure hole quality and work efficiency.

4. Keep clean: After drilling, promptly remove metal shavings and cutting fluid to keep the work area clean, ensuring safety and accurate operation.

5. Avoid overheating: Control the usage time of the drill bit to avoid overheating, which can affect its performance and lifespan.
