Features Precision Drilling Angle: First position at a 45-degree angle for optimal results, then drill vertically for clean holes in various materials Versatile Compatibility: Designed to fit bench drills, power drills, and machine tools for enhanced functionality, not suitable for impact drills Multi-Material Application: Ideal for drilling through stone, ceramic, vitrified tile, and glass, ensuring versatility for different projects Efficient Chip Removal: Sectioned cutting edges minimize cutting resistance and promote quick chip removal for smoother operation Enhanced Stability: Universal triangle shank design prevents skidding and allows for better torque handling during drilling tasks Features: 1、Firstly position at an oblique angle of 45 degree, then drill the hole vertically (note low speed about 800-1000rpm). 2、Fit for bench drill, power drill and machine tools with drilling function but not for impact drill (Cannot use the impact function to drill). 3、Suitable for drilling on stone, ceramic, vitrified tile, glass, etc. You need to constantly adding water to cool in the proc of drilling. 4、The cutting edges of drill bit adopts section design for reduced cutting resistance, also conductive to chip removal. 5、Universal triangle drill shank can effectively prevent skidding during drilling and bear more torque. 6、Long oval hole on the drill bit is more conductive to the discharge of the chippings.
