Product Description
Professional Diamond Core Drill Bit for Granite Marble Stone Cutting
1.Premium Material Composition: Crafted from M35 cobalt steel, incorporating an extra 5% cobalt to enhance hardness and thermal resilience. Attaining a Rockwell hardness of up to 65, it delivers faster cutting speeds and extended longevity, lasting 12 times longer than standard HSS bits.
2.Precise Centering Feature: Equipped with self-centering capability. The 135° split point guide automatically centers, enabling rapid penetration under light pressure. The straight shank ensures secure fixation and accurate alignment, compatible with standard and circular drill trays.
3.Rapid and Effective: Facilitates high-efficiency drilling without wandering. Enables quicker and easier removal of chips and debris.
4.Economical Choice: Offers the lowest cost per drilled hole. The solid cobalt steel bit can be resharpened for repeated use.
5.Split Point Design: Permits direct drilling to the required dimension, eliminating the need for pre-drilling.
6.Broad Application: Suitable for drilling stainless steel, copper, cast iron, galvanized pipe, iron, aluminum alloy, and other non-heat-treated metals with hardness below HRC38.
