Carbide-tipped hole cutters are specialized tools used for drilling holes in various materials. With tips made of tungsten carbide, they have extremely high hardness and wear resistance, allowing them to easily handle stainless steel, cast iron, aluminum, copper, wood, plastic, and more. Due to the high hardness and heat resistance of tungsten carbide, these tools excel in maintaining sharpness and durability, making them suitable for precise and high-strength cutting tasks.

Usage Instructions
Preparation:
Ensure you are using a suitable drill or drilling machine and adjust the speed as needed.
Select the appropriate diameter carbide-tipped hole cutter and install it on the drill or drilling machine.
Make sure the work area is clean and the material surface is flat.

Positioning and Fixing:
Use a hole cutter with a center drill to help better position and start the hole.
Secure the material to prevent movement or vibration during drilling.

Starting to Drill:
Start the drill at an appropriate speed and pressure to begin cutting the material.
Gradually apply pressure to avoid excessive force that could damage the tool or material.
Maintain stability during drilling to avoid excessive vibration.

Cooling and Lubrication:
When cutting hard materials like metal, use coolant or lubricant to effectively reduce heat buildup and extend the tool's life.
Regularly stop to check the tool's condition and add coolant or lubricant as needed.
Precautions

Safety:
Wear appropriate safety gear such as goggles and gloves before use.
Ensure the work area is free of bystanders to avoid accidental injury.

Tool Inspection:
Check the tool for damage or wear before use to ensure it is in good condition.
Regularly maintain and replace worn tools to avoid safety incidents or decreased work quality due to tool damage.

Operation:
Maintain a stable speed and pressure during cutting, avoiding sudden force increases or high-speed operation.
Monitor the tool for overheating during cutting and pause work if necessary to allow for cooling.

Material Selection:
Choose the appropriate cutting speed and cooling method based on the material to ensure optimal cutting results.
Ensure the material is securely fixed to avoid vibration or movement that could affect the cutting quality.

By using and maintaining them correctly, carbide-tipped hole cutters can provide efficient, precise, and durable cutting in various materials, making them indispensable in professional and industrial applications.
