Tapered Button Bits Application Case for Mining Quarrying and Bolt Hole Drilling Projects

Case Overview

This application case demonstrates how Tapered Button Bits deliver efficient, reliable rock drilling across mining, quarrying and tunneling projects. The client needed a durable drill bit solution capable of handling shallow hole drilling in varied rock conditions while working with existing drill rods and equipment.

Project Background

The customer operates multiple drilling sites across quarrying, mining and infrastructure projects, working with a fleet of air leg rock drills fitted with H19, H22 and H25 tapered rods. They required a single bit series that could cover shallow hole drilling tasks across varying rock hardness while keeping changeover time and consumable costs low.

Customer Challenge

The customer's drilling operations required bits that could perform consistently in both soft and hard rock formations, minimize downtime between bit changes, and integrate with their current H22 tapered drill rods. Frequent bit wear and poor cuttings removal were slowing down project timelines and increasing operating costs across multiple job sites.

Our Solution

We supplied Tapered Button Bits configured to match the customer's equipment and rock conditions:

• Taper connection: 6-degree, 7-degree, 11-degree and 12-degree angles for compatibility with H19, H22 and H25 rods.
• Button configurations: 4-button, 5-button, 6-button and 7-button layouts with face and gauge buttons.
• Carbide profiles: spherical, ballistic and parabolic profiles for optimal penetration and longevity.
• Forged and heat-treated body: for strength and wear resistance in demanding conditions.
• Skirt designs: short-skirt, standard-skirt and long-skirt options to match drilling preferences.
