hardness center punch constructed from carbon steel, with the tip individually heat treated to deliver hardness and durability for long service life. Nonslip round knurled shank provides a secure grip for enhanced control and accuracy during use. Tapered punch point with a dimple creates an exact starting spot for drilling, helping to prevent wandering and improve hole accuracy. Versatile punch locator suitable for a wide range of materials including cast iron, mild steel, brass, bronze, copper, aluminum, wood, plastics, and polymers. Use scenarios: Metalworking: mark true centers on steel plates or castings before drilling to ensure precise hole placement. Woodworking: locate center points on boards for accurate pilot holes and clean starting marks. Plastics and polymers: initiate starting marks with minimal drift to guide subsequent drilling or machining. Key attributes: function as a center punch, compatible with diverse materials, durable carbon steel construction, knurled grip for control, tapered point for accuracy, and a dimpled tip to start holes precisely.
