Description：
A tapered button bit is a durable and efficient drilling tool widely used in mining, tunneling, quarrying, and construction industries. It is designed with a tapered body that ensures a secure connection with drill rods, providing excellent stability and energy transfer during drilling operations.
The tapered button bit works efficiently with hand-held rock drills and pneumatic drilling rigs, making it ideal for small to medium-sized drilling applications. It is available in different taper angles (e.g., 7°, 11°, 12°) to match specific drilling requirements. The bit’s optimized design minimizes energy loss, enhances drilling speed, and extends service life, reducing overall operational costs.
With its strong performance, high durability, and reliable structure, the tapered button bit is a preferred choice for professionals seeking cost-effective and long-lasting drilling solutions.
