Certainly! Here’s a concise description of 4.8mm straight shank twist iron drill bits, along with key highlights:

Material: These drill bits are manufactured from M35 cobalt steel with 5% cobalt content. The cobalt addition creates a hardened alloy, resulting in a Rockwell hardness of up to 65. Compared to average HSS (high-speed steel) bits, these cobalt steel bits offer much faster cutting and an extra-long lifespan—up to 10 times longer
HSS Titanium Coating: Classic HSS construction with a titanium coating enhances capability and durability. The cutting edge is hardened and honed for sharpness.
Flutes Form: The 2-flute design helps clear chips and debris away from the bit, reducing friction and heat during drilling. This results in a faster, cooler drilling process and a chatter-free experience.
Straight Shank and 135° Point Angle: The straight shank allows compatibility with standard drill chucks and collet chucks, ensuring accurate centering. The helical flute design facilitates easy swarf removal. These bits are ideal for general-purpose drilling applications.
Application: Particularly successful in cutting through hard metals (with hardness less than HRC38°), such as stainless steel and cast iron. They can also be used for softer materials like copper and aluminum, but not for hardened steel or high carbon steel
