4 Degree 32mm Taper Button Bit Rock Drilling Tool
Product Overview
The 4 Degree 32mm Taper Button Bit is a professional rock drilling tool designed for use with tapered drill rods. With a 32mm drilling diameter and 4 degree tapered connection, this bit provides stable impact energy transmission and efficient rock penetration.
The bit body is manufactured from high-strength alloy steel and processed through controlled heat treatment to improve hardness, toughness, wear resistance, and overall durability. Tungsten carbide buttons are precisely positioned on the bit face to provide effective rock breaking performance and maintain stable drilling efficiency during continuous operation.
This tool is suitable for a wide range of small diameter rock drilling applications, including mining, quarrying, construction, stone drilling, and general rock excavation.

Key Features & Benefits
Durable Alloy Steel Body
The bit body is manufactured from high-quality alloy steel with optimized heat treatment. This material provides an optimal balance between hardness and toughness, enabling the bit to withstand repeated impact loads and abrasive rock conditions.
The reinforced bit body design helps reduce deformation and premature wear during drilling operations, making it suitable for continuous drilling applications.
Wear Resistant Tungsten Carbide Buttons
The drilling buttons are manufactured from wear-resistant tungsten carbide material. These carbide buttons directly contact the rock formation and provide effective crushing and penetration performance.
The strategic button layout is engineered to distribute drilling force evenly across the working face, helping maintain consistent drilling performance and reducing uneven wear patterns.
Efficient Rock Breaking Performance
The 4 degree tapered design provides a reliable connection between the button bit and tapered drill rod. This configuration helps transfer impact energy efficiently from the drilling equipment through the drill rod to the bit.
During operation, the carbide buttons penetrate and crush the rock surface while the bit rotates, achieving efficient hole formation and maintaining stable drilling speed throughout the operation.
Stable Taper Connection System
The tapered shank provides a secure connection with the corresponding tapered drill rod. The 4 degree taper geometry allows for convenient installation and removal while maintaining reliable contact during drilling operations.
A properly matched tapered drill rod and button bit combination helps improve impact energy transmission efficiency and reduces unnecessary energy loss, resulting in enhanced drilling performance.
