1. What materials are used in the manufacturing of these tapered bits?
The bits are constructed using high-quality Carbon Steel or Alloy Steel Bar 45CrNiMoV, combined with durable Tungsten Carbide Tips (YK05 or T6 grade) for superior drilling performance.
2. What taper angles and connection sizes are available?
We offer standard taper angles of 6, 7, 11, and 12 degrees. Shank sizes typically include 19mm, 22mm, and 25mm to fit various hex rods.
3. Can the color of the tapered bits be customized?
The standard spray-paint colors available are Red, Black, Yellow, and White. These coatings help protect the bits from corrosion during transport and storage.
