FAQs
What is the best drill index for steel?
When working with steel, durability and heat resistance are critical. The best drill index for steel typically features cobalt or titanium-coated bits. Cobalt drill bits, often containing 5–8% cobalt alloy, can withstand higher temperatures and resist wear, making them ideal for drilling through hardened steel. Titanium-coated bits are also effective, but they may wear down faster when used repeatedly on tough metals. A well-organized index with a full range of sizes ensures you always have the right bit on hand for precise work.
Is a 118 or 135 drill bit better?
The answer depends on your application. A 118-degree drill bit has a sharper point and is better for softer materials like wood and plastic, offering faster penetration. A 135-degree split-point bit, on the other hand, is preferred for steel and harder materials. It reduces walking at the start of drilling, requires less pressure, and offers greater accuracy. For most metalworking tasks, a 135-degree bit is the better choice.
What is the best brand of drill bits?
Several brands are known for producing high-quality drill bits. Irwin, DEWALT, Norseman, and Milwaukee consistently receive strong reviews from professionals and hobbyists alike. For heavy-duty metal drilling, Norseman’s cobalt indexes are often recommended for their exceptional performance and long lifespan. DEWALT and Milwaukee also stand out for offering versatile sets that balance durability with affordability.
Which brand is best for drilling?
The best brand for drilling depends on your needs. For professional-grade durability and precision, Norseman is a top pick, especially for steel and other hard materials. DEWALT is widely recognized for its reliable all-around performance, making it a favorite among contractors and DIYers. Milwaukee also delivers excellent results, particularly in jobsite environments where toughness matters most. If you’re seeking long-lasting bits that can handle a wide variety of tasks, these three brands are consistently among the best.
Conclusion
In the end, choosing the best drill index comes down to matching the right set with your specific needs. A well-built index not only keeps your bits organized but also ensures you have the precision and durability required for every project. Whether you’re drilling into wood, tackling tough steel, or preparing for daily professional use, investing in a quality set pays off in accuracy, efficiency, and tool longevity. With reliable options available from trusted brands, the key is to balance performance, versatility, and value.
