Button-Type Drill Bits - Function, Application, Features & Maintenance Tips

Button-type drill bits are engineered for high-impact rock drilling, making them a top choice for professionals seeking the best drill bit for drilling into rock for shallow to medium-depth applications. Their carbide button design delivers powerful cutting force, ideal for drilling holes in rocks in various projects. This article explores how to drill a hole in rock using button-type drill bits, their features, applications, and maintenance tips, highlighting their role in efficient drilling through rock.

What Are Button-Type Drill Bits?

Button-type drill bits feature a tip embedded with tungsten carbide buttons that deliver high impact force to break rock surfaces (Epiroc, 2019). Designed for use with hammer drills, these bits are ideal for drilling rock with a hammer drill in shallow to medium-depth holes, typically 0.5–5 meters, in formations like granite or limestone (Kang et al., 2018). Available in diameters from 35–127 mm, they are suited for both surface and underground hard rock drill applications, such as drilling a hole in a rock for fencing or construction.

The button design maximizes impact efficiency, ensuring fast penetration and durability in drilling into rock with moderate abrasion.

Applications of Button-Type Drill Bits

Button-type drill bits are used in:

• Construction: Drilling holes in rocks for foundation bolts or fence posts.

• Quarrying: Creating shallow holes for rock splitting or small-scale extraction.

• Mining: Drilling blast holes in medium-depth hard rock formations.

• Landscaping: Drilling small holes in rocks for decorative or jewelry purposes.

Litian Heavy Industry’s button-type drill bits, with optimized carbide layouts, enhance efficiency in construction and quarrying projects.

Key Features and Benefits

• High Impact Force: Carbide buttons deliver strong cutting power, making them the best drill bit for hard stone in shallow drilling (Holmberg et al., 2017).

• Fast Penetration: Optimized button geometry ensures quick drilling, reducing project timelines.

• Durability: Tungsten carbide buttons resist wear in hard rock abrasive conditions.

• Versatility: Suitable for various rock types, from granite to soft limestone.

Maintenance Tips for Button-Type Drill Bits

To maintain button-type drill bits:

• Inspect Buttons: Check carbide buttons for wear or damage after each use (American Pneumatic Tools, n.d.).

• Clean Debris: Remove rock dust to prevent friction, especially in wet drilling conditions.

• Replace Worn Bits: Timely replacement ensures consistent performance in drilling holes in rock.

• Store Properly: Keep in a dry environment to prevent corrosion of carbide rock drill bits.

Maintenance can extend bit life by up to 20%, reducing costs in rock drilling bits applications (Holmberg et al., 2017).

Button-Type Drill Bits Overview

Button-type drill bits are the best drill bit for rocks in shallow to medium-depth applications, offering high impact force and versatility for drilling through rock. Ideal for construction, quarrying, and mining, they ensure efficient, durable performance. With high-quality options from Litian Heavy Industry, professionals can achieve reliable results in rock drilling projects.
