What is the temperature at tip of carbide twist drill?

The temperature at the tip of a carbide twist drill can reach between 500°F to 1,200°F (260°C to 650°C) during operation, depending on factors such as cutting speed, feed rate, and the material being drilled. High temperatures can affect tool wear and performance, making effective cooling and lubrication essential to prolong tool life and maintain drilling efficiency. Proper selection of cutting parameters helps manage these temperatures effectively.
