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
FEATURE:DESCRIPTION
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).
