Product Overview

A retractable button bit designed for small-to-medium diameter drilling (32-64mm), combining a retraction mechanism with button-shaped tungsten carbide inserts. Ideal for applications requiring frequent bit withdrawal in complex geological conditions.

Key Features

Retractable Design: Enables safe withdrawal during drilling to prevent jamming in fractured/abrasive formations.
R32 Thread Connection: Standard R32 threaded shank compatible with most drill rigs (e.g., DTH, top hammer).
Button Inserts: Spherical/wedge-shaped carbide tips for high wear resistance (suitable for medium-to-extremely hard rock).
Optimized Flushing: Internal fluid channels ensure efficient cuttings removal and bit cooling.

Applications

Geotechnical Exploration: Core sampling, blast hole drilling.
Mining: Small-diameter blast holes, anchor bolt holes.
Civil Engineering: Tunnel support drilling, micropile foundations.
Challenging Formations: Unstable layers (e.g., fault zones, loose gravel).
