Overview

Where the Rock Actually Breaks: Drill King's DTH Button Bits

The button bit is the cutting edge of the DTH drill string β€” the component that actually fractures rock at the bottom of the hole as the hammer delivers percussive force above it. Getting the bit right matters more than almost any other tooling decision: face shape, button placement, and carbide grade all directly determine penetration rate, hole straightness, and service life.

Drill King manufactures DTH Button Bits across the broadest size range in our catalog β€” 2-3/4″ (70mm) through 42″ (1067mm) β€” as one of the only truly custom bit manufacturers in the industry, with one of the largest stocking selections of configurations in the Western Hemisphere. Every bit is built to aerospace manufacturing standards and ISO 9001:2015 quality certification.

Aerospace-Grade Construction

Manufactured to aerospace standards and ISO 9001:2015 quality certification, using premium tungsten carbide grades.

Multiple Face Designs

Configurations suited to specific ground conditions β€” from straight-hole stability to maximum penetration rate in fractured or competent rock.

Diamond-Enhanced Options

Diamond-impregnated carbide available for the most abrasive, demanding formations where standard carbide wears too fast.

Extended Wear Options

Side carbide wear pads and back-reaming carbide buttons available to extend bit life and improve hole conditioning.

Configuration Options

Built Around Your Ground Conditions

Convex face designs for hard, abrasive rock where high penetration rate and long service life matter most.

Concave face designs for excellent all-round performance across hard and soft formations, with strong hole straightness and low vibration.

Flat face designs for general-purpose drilling, very broken ground, and soft formations prone to over-drilling.

The CC KRUSHER bit, combining three distinct face angles to deliver straight-hole drilling and excellent penetration rates in a single design.
