In this article, we'll go over some of the most important points to consider when choosing the right drill bit for the job. Hardened metals and nonferrous metals should be drilled with Cobalt bits, while bright-finished bits are best suited for abrasive surfaces.
Cobalt drill bits are preferred for hardened metals
If you're working with a hardened metal, cobalt drill bits are the right choice. Cobalt drill bits have a higher cobalt content than high-speed steel and are ideal for drilling stainless steel and cast iron. These drill bits feature Bosch's speed helix design, which gets the right bit through the material faster. They are also more resistant to corrosion and wear thanks to their double-fluted balanced construction.
Cobalt drill bits are available in two different ratios. M35 has 5% cobalt, while M42 has 8%. Generally speaking, the higher the cobalt percentage, the more brittle the drill bit is. The M42 cobalt drill is recommended for controlled drilling situations and applications that require low-speed drilling. The M35 cobalt drill has lower cobalt content, but has excellent abrasion and red hardness.
HSS drill bits are ideal for nonferrous metals
High-performance HSS drill bits can efficiently and effectively drill holes in nonferrous metals, including steel, alloyed steel and cast iron. These bits have a split point drill tip that enables 40% faster drilling and 50% lower feed pressure. The chisel edge and 135-degree split-point tip minimize friction and heat. They are suited for drilling nonferrous metals, including nonferrous and alloyed steel, cast iron, hard plastics, and more.
High-speed steel drill bits have a high level of hardness and wear resistance. They are designed to work in extreme temperatures, so they can endure high levels of heat. While they are able to withstand heat, oiling them before drilling thicker metal or deeper holes is recommended. They can also be used on soft metals such as stone, wood and plastic. It is important to note that HSS drill bits should never be used on masonry, as bricks will immediately ruin their cutting edge.
Solid carbide bits are ideal for abrasive surfaces
When you are considering the purchase of solid carbide drill bits, you should consider how much they cost. However, be aware that high-quality drill bits can wear out quickly, so you should avoid soaking them for an extended period of time. Drill bits with carbide coatings can be sharpened using a diamond-surface grinding wheel. Moreover, you can also get a drill bit holder to display your bits and keep them organized.
If you are considering solid carbide drill bits for your drilling needs, you should make sure that you choose those that are coated with tungsten. This coating increases the bit's hardness and resists wear, thereby reducing delamination. Carbide is tough, durable, and forgiving to human operations. Carbide bits come with a black oxide coating to help retain lubricant. Other coatings include titanium nitrate, which provides extended wear. Titanium aluminum nitrate also provides high heat and abrasion resistance. Finally, you should consider a multilayer of silicone for ultra-dense metals.
Bright-finished bits are inexpensive
If you're looking for drill bits that are inexpensive but have high quality, consider buying those that are bright-finished. This type of finish isn't a coating, but a shiny finish that's commonly used for general wood and soft metal work. Bright-finished drill bits are often not coated, but can still be durable and long-lasting if properly used. A bright-finished drill bit is typically found in most woodworking supplies. Bright-finished drill bits are also more affordable than the more expensive types of drill bits.
When comparing drill bits, it's important to look for the HSS designation. HSS stands for high-speed steel, so it's likely to be a good choice for most applications. But what about cobalt-finished bits? They have an added element of cobalt, which gives them a higher degree of heat hardness. Cobalt-finished bits can also drill stainless steel more effectively than plain HSS bits. Titanium-coated HSS drill bits have an added titanium coating, which helps disperse heat from the cutting edge, and can make the drill run faster.
