Q7-33-R25 threaded button bits
Q7-33-R25 threaded button bits are a type of drill bit commonly used in mining, quarrying, and other rock drilling applications. Let’s break down the designation to understand its components:
- Q7: This typically refers to the quality or grade of the drill bit. Different manufacturers may have their own grading system, but Q7 often indicates a high-quality bit designed for demanding applications.
- 33: This number likely refers to the diameter of the drill bit, measured in millimeters (mm). A 33mm diameter bit is a common size for many drilling applications.
- R25: This refers to the threading standard used on the shank of the drill bit. R25 threading is a specific type of thread that allows the drill bit to connect securely to a drill rod or other extension. It ensures that the bit can transmit torque and force effectively during drilling operations.

Threaded button bits like the Q7-33-R25 are typically made from high-strength steel alloys to provide durability and resistance to wear and tear. The button at the tip of the bit is designed to break up and remove rock material as the bit rotates and is pushed into the rock formation.
When using threaded button bits, it’s important to ensure that the threading on the bit matches the threading on the drill rods or extensions being used. This ensures a secure connection and effective transfer of torque and force. It’s also important to follow the manufacturer’s recommendations for maintaining and replacing worn or damaged bits to ensure optimal drilling performance and safety.
