• Precision-ground 82-degree tip drills countersink holes into most machinable metals, as well as wood and plastic.
• Universal 1/4 inch hex shank prevents slipping in standard chucks and is compatible with all 1/4 inch quick-change chucks, including impact drills.
• Chamfering device: five blade, which can discharge the sawdust more quickly, drill out smooth and smooth sinks, and insert the screw cap into the surface of the workpiece.
• The material of the countersunk bit is different. The center of the countersunk bit is inlaid with a piece of hard alloy, while the whole body of the countersunk bit is made of high-speed steel.
• The appearance is different. Countersunk drills are generally of equal diameter, and the diameter of the carbide outer edge of the countersunk drill head is slightly larger than the diameter of the drill body.
• The tail part has various shapes, such as square, triangle, spiral due to the different connection form with the countersunk drill.
• The cutting edge is different. The cutting edge of the countersunk drill is used for metal cutting. It has a certain angle and slope, and the cutting edge is sharp, while the electric hammer countersunk drill has no cutting edge and only chamfers on both sides.
