What sizes and specifications are available for R32 Button Bits?
R32 Button Bits come in diameters ranging from 51mm to 76mm. They are configured with varying button layouts (such as 6x10 to 8x11 gauge buttons) and gauge tooth angles of 30° or 35° depending on the model.
What is the difference between a standard Button Bit and a Retrac Button Bit?
Standard button bits are designed for general drilling, while Retrac button bits feature special rear grooves to facilitate easier retrieval of the drill string in loose or fractured rock formations.
What are the primary applications of Self Drilling Anchor (SDA) Bolts?
SDA Bolts are extensively used in geotechnical applications including slope stabilization, tunnel pre-support (such as umbrella arch systems), foundation reinforcement with micropiles, and railway and subway engineering.
Which thread types and rod sizes are supported in this drilling tool range?
We support standard thread sizes including R32, R38, T38, T45, and T51. Rod sizes include H32, H38, D32, D39, D46, D52, D56, D64, D76, and D87 to cover various rock drilling requirements.
