Complete Buying Guide for Best Drill Index Set
Essential Factors We Consider
Choosing the best drill index set involves looking beyond just the number of bits. Consider the material of the drill bits: High-Speed Steel (HSS) is good for general purpose work, while Cobalt (M35 or M42) is superior for drilling hardened metals and stainless steel due to its heat resistance. Titanium Nitride (TiN) coated bits offer enhanced durability and reduced friction, extending bit life. The point angle (e.g., 118-degree for general use, 135-degree split point for self-centering on hard materials) and shank type (round, hex, flatted) also play a crucial role in performance and compatibility with your drill. Finally, evaluate the quality of the index case – a durable, clearly labeled case protects your investment and ensures easy bit selection.
Budget Planning
Your budget will significantly influence your choice of a drill index set. Basic HSS sets are the most affordable and suitable for occasional light-duty tasks. Mid-range HSS with coatings like TiN, or entry-level cobalt sets, offer a great balance of performance and value for regular use on varied materials. Premium cobalt sets, especially those with a wide range of sizes, represent a substantial investment but deliver unparalleled performance and longevity for professional and heavy-duty applications. Always consider the long-term value: a more expensive, durable set might save you money on replacements in the long run.
Final Thoughts
When selecting your best drill index set, align your choice with your most frequent tasks and the materials you typically work with. For general purpose and softer metals, a quality TiN-coated HSS set like the DEWALT is an excellent all-rounder. If you consistently tackle hardened steel, cast iron, or stainless steel, investing in a robust cobalt drill bit set from Champion or the specialized M35 options will prove invaluable. Prioritize quality, a suitable range of sizes, and a durable index case to ensure your drill bits are always ready for action.
Frequently Asked Questions
Q: What’s the main difference between HSS and Cobalt drill bits?
A: HSS (High-Speed Steel) drill bits are good for general-purpose drilling in wood, plastic, and softer metals. Cobalt drill bits (typically M35 or M42) are an alloy of HSS with 5-8% cobalt, which significantly increases their heat resistance and hardness, making them ideal for drilling through tougher materials like stainless steel, cast iron, and hardened alloys.
Q: What does a 135-degree split point mean, and why is it important?
A: A 135-degree split point (or self-centering point) means the tip of the drill bit is ground to a sharp angle that creates two cutting edges. This design prevents the bit from “walking” or wandering when starting a hole, especially on curved or uneven surfaces, eliminating the need for a pilot hole or center punch. It also reduces thrust force, making drilling easier and more efficient in harder materials.
Q: How do I maintain my drill index set to ensure longevity?
A: To maximize the life of your drill index set, always use the correct bit for the material. Apply cutting fluid or coolant when drilling metals, especially hard ones, to reduce heat and friction. Clean bits after use and return them to their designated slots in the index case to prevent damage and corrosion. Avoid excessive pressure, let the bit do the work, and sharpen dull bits promptly or replace them.
Q: Why is a good drill index important?
A: A good drill index is crucial for organization, protection, and efficiency. It keeps drill bits neatly arranged by size, saving time on finding the right bit. It protects the delicate cutting edges from impact damage when not in use, extending their lifespan. An organized index also encourages proper bit selection, preventing the misuse of bits and improving drilling accuracy.
Q: Can these bits drill through stainless steel?
A: Yes, many of the recommended bits, particularly the cobalt drill bit sets (like products #3 and #4) and high-performance HSS bits with advanced coatings (like Champion Brute Platinum #5), are specifically designed for drilling through stainless steel. When drilling stainless steel, it’s critical to use proper technique: maintain a consistent feed rate, use a slower RPM, and always apply cutting oil to manage heat.
Selecting the best drill index set is a critical decision that impacts the quality of your work and the longevity of your tools. By considering the material, features, and your specific needs, you can find a set that will serve you reliably for years to come. Whether you opt for the versatility of DEWALT’s titanium-coated bits, the robust speed of Champion’s HSS, or the heavy-duty power of a cobalt set, investing in a quality drill index is an investment in your craftsmanship.
