Audited Supplier some more details about TC (Tungsten Carbide) drill bits:
Helix Angle: TC drill bits feature a helical or spiral flute design with a specific helix angle. The helix angle refers to the angle formed between the cutting edge and the axis of the drill bit. Different helix angles are used for different materials and drilling applications. Steeper helix angles facilitate efficient chip evacuation, while shallower angles provide better stability and control during drilling.
Chisel Edge and Point Angle: The chisel edge is the primary cutting edge of the drill bit, located at the center of the tip. The point angle refers to the angle formed by the chisel edge. Common point angles for TC drill bits range from 118 degrees to 135 degrees. The selection of the point angle depends on the material being drilled and the specific drilling requirements. Different point angles provide variations in cutting behavior and chip formation.
Coolant and Lubrication: When drilling with TC drill bits, the use of cutting fluids or lubricants is often recommended. These fluids help to cool the drill bit and the workpiece, reducing heat buildup and extending tool life. Lubrication also aids in chip evacuation, improves cutting performance, and reduces the friction between the drill bit and the material being drilled.
Carbide Tip Replacements: In some cases, when the carbide tip of a TC drill bit becomes dull or damaged, it can be replaced instead of discarding the entire drill bit. This allows for cost savings and reduces waste by extending the useful life of the drill bit. Replacement carbide tips can be purchased separately and installed onto the existing steel shank.
Cutting Speed and Feed Rate: The cutting speed and feed rate are critical parameters in drilling operations. The cutting speed refers to the rotational speed of the drill bit, usually measured in revolutions per minute (RPM). The feed rate is the rate at which the drill bit is advanced into the material, measured in units of distance per revolution (e.g., millimeters per revolution). Optimal cutting speed and feed rate depend on the material being drilled, the drill bit size, and the desired drilling performance. Following recommended guidelines or consulting machining references can help determine the appropriate cutting parameters.
Noise and Vibration: TC drill bits can generate noise and vibrations during drilling, especially when drilling hard materials or using high speeds. It is important to wear appropriate hearing protection and ensure the drilling machine is properly secured or mounted to minimize any potential hazards associated with noise and vibration.
Quality and Brand Considerations: When selecting TC drill bits, it is advisable to choose reputable brands known for their quality and reliability. High-quality drill bits are often made with precise manufacturing processes, ensuring consistent performance, accurate hole sizing, and extended tool life. Reading product reviews and seeking recommendations from professionals or experienced users can help in identifying reliable brands.
Customization: In some cases, TC drill bits can be customized or specially made to meet specific drilling requirements. Customization may involve adjusting the flute geometry, point angle, or other parameters to optimize performance for unique applications or materials.
Remember to always refer to the manufacturer's guidelines and recommendations for proper usage, maintenance, and safety precautions when using TC drill bits.

FAQ:
Can TC drill bits be used for drilling in thin sheet metal?
A: Yes, TC drill bits can be used for drilling in thin sheet metal. It is advisable to use a slower drill speed and apply light pressure to prevent the material from deforming or tearing.
Q: Can TC drill bits be used for drilling in automotive body panels?
A: TC drill bits can be used for drilling in automotive body panels. It is important to use a slower drill speed, apply light pressure, and use a backing material to prevent excessive damage to the panel.
Q: Can TC drill bits be used for drilling in circuit boards?
A: TC drill bits are not typically recommended for drilling in circuit boards, as specialized PCB (Printed Circuit Board) drill bits are designed specifically for this application.
Q: Can TC drill bits be used for drilling in jewelry materials?
A: Yes, TC drill bits can be used for drilling in jewelry materials such as gold, silver, or titanium. They provide precise drilling without causing excessive damage or deformation.
Q: Can TC drill bits be used for drilling in hardened glass?
A: TC drill bits are not recommended for drilling in hardened glass. For drilling in glass, specialized diamond-tipped drill bits or carbide-tipped glass drill bits are more suitable.
