Drill bits are essential tools used across industries. Coatings enhance their durability, lifespan, wear resistance, heat tolerance, and cutting efficiency. If you’re looking to buy drill bit or wholesale drill bit, understanding the coatings’ benefits is key.
Types of Coatings for Drill Bits
Bright Coating (No Coating)
A bright finish or no coating shows the drill bit’s inherent quality. For those seeking customized industrial tools, bright-coated bits are suitable for lighter tasks.
Cobalt Amber Coating
Cobalt Amber Coating, used on cobalt twist drill bits, offers excellent heat resistance and durability, making it ideal for tough materials like stainless steel and cast iron. Industrial tools manufacturers apply this coating for heavy-duty applications requiring strength and longevity.
Titanium Nitride (TiN) Coating
TiN coating provides superior hardness and is highly effective for drilling aluminum, steel, and plastics. If you’re looking for industrial tools suppliers offering high-performance products, TiN-coated drill bits ensure long-lasting results.
Black Oxide Coating
Black Oxide coating offers corrosion resistance and reduces friction, making it ideal for general-purpose drilling. If you want to buy drill bits at an affordable price, black oxide-coated options are reliable for a variety of applications.
Titanium Carbonitride (TiCN) Coating
TiCN enhances heat resistance and durability, making it perfect for heavy-duty tasks like drilling stainless steel and high-carbon steels. Many industrial tools suppliers offer TiCN-coated drill bits for high-performance applications.
These coatings are commonly applied to various high-speed steel (HSS) products, including: HSS Twist Drill Bit, HSS Step Drill Bit, HSS Machine & Hand Taps, HSS End Mills, HSS Hole Saws.
By applying coatings like TiN, TiCN, and Cobalt Amber, these HSS tools offer improved performance, durability, and longevity. Whether you’re looking to wholesale drill bits or buy customized industrial tools, coated products provide long-lasting, efficient results.
