• 【Material】: The center drill is crafted from premium materials (such as high-speed steel), ensuring robust durability while enhancing wear resistance and enabling efficient chip evacuation.
• 【Convenience】: Easy to use and install, allowing for quick drill bit replacement with one hand.
• 【Precision Machining】: Center drills and locating drills are used to create tapered holes on lathes, providing a starting point for standard twist drills. Their design prevents drill bit deflection.
• 【Chip Removal】: Wide spiral flutes enhance chip evacuation and heat dissipation, minimizing breakage risks from poor chip clearance. Use slightly higher speeds; if speeds are too low, the blade may feel dull.
• 【Versatile Applications】: Center drills work with lathes to drill holes in mold steel, cast iron, aluminum, carbon steel, wood, threaded dies, and other hard materials, enhancing drilling efficiency.
