THUNDERWEB™ DIN 338 drill bit cassettes feature a conical web design that is thicker toward the back of the bit, providing greater strength than standard drill bits. The parabolic web cross-section and optimised flute geometry allow rapid chip ejection and better heat dissipation, extending bit life. A 135° split point ensures precision starts without walking on the material, while the polished finish reduces friction for smoother drilling. The impact-resistant ABS case with rubber corner protection keeps the bits secure and protected, and the robust design tolerates higher feed pressure and torque, minimising breakages.
