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:

Threaded Button Bit
Diameter: 30mm, 32mm, 33mm, 35mm, 38mm, 41mm, 43mm, 45mm, 48mm, 51mm, 57mm, 64mm
Skirt body: retrac, and normal,
Face: flat, uniface,
Carbide: Dome, ballistic
Used in drifting and tunneling, dimensional natural stone quarrying
To match shank rod, and MM and MF Hex drifter rod for light-duty top hammer

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.
