Description
Material: The drill bits in the Cobalt Range are made of high-speed steel (HSS) with a cobalt alloy (usually around 5-8% cobalt content). This cobalt addition increases the hardness and heat resistance of the drill bits, making them suitable for drilling through tough metals.
Bit Types: Metal drill bits in the Cobalt Range are typically twist drill bits, the most common type for general-purpose metal drilling. They are available in various lengths and diameters.
Sizes: The Cobalt Range of metal drill bits offers a range of sizes, specified in diameter measurements (e.g., 1/16", 1/8", 3/16", 1/4", etc.), to accommodate different hole sizes in metal.
Shank Types: Cobalt drill bits generally have standard round shanks that fit into the chuck of most drill machines.
Point Geometry: The drill bits in the Cobalt Range may have different point geometries optimized for metal drilling, ensuring efficient cutting and reduced heat buildup.
Flute Design: Metal drill bits in the Cobalt Range typically have straight flutes that facilitate effective chip evacuation during drilling.
Coating: Some cobalt drill bits may come with a surface coating (e.g., titanium nitride or black oxide) for added lubricity and further reducing friction during drilling.
Application: The Cobalt Range of metal drill bits is designed specifically for drilling through hard metals, making them suitable for stainless steel, cast iron, bronze, and other high-strength alloys.
Storage: These drill bits may come in individual packaging or as part of a set, with storage cases or holders to keep them organized and easily accessible.
Safety: When drilling hard metals, it’s essential to use appropriate cutting fluid or lubricant to prevent overheating and extend the life of the drill bits.
