The Ultimate Buying Guide to the Best Drill Bits for Metal
Not all drill bits are made the same. While most drill bits can be used on wood, not all can endure metal. Drill bits for metal are essential tools for any DIY enthusiast or professional who frequently works with metal materials. However, with so many options available, it can be challenging to find the right drill bits for your specific needs. In this comprehensive guide, we will walk you through the key features to consider when choosing drill bits for metal, ensuring you make an informed decision.
What to Consider When Buying Drill Bits for Metal Projects
Material
Manufacturers primarily make drill bits from three materials – high-speed steel (HSS), cobalt, or carbide. HSS drill bits are the most common and suitable for drilling softer metals, providing good performance at an affordable price. Cobalt drill bits offer enhanced durability and heat resistance, making them ideal for drilling harder metals. Carbide drill bits are the most durable and capable of drilling through the toughest metals, but they are also the most expensive.
Size
Consider the diameter and length of the drill bits. The diameter determines the size of the hole, while the length determines the depth of the hole. Ensure you choose the appropriate drill bit sizes based on your project requirements.
Shank Type
Drill bits come with round or hexagonal shanks. Round shank bits are compatible with most drills and offer easy installation and removal. Hexagonal shank bits provide better grip and prevent slippage, making them suitable for high-torque applications.
Point Angle
Drill bits for metal are available in two common point angles – 118 degrees and 135 degrees. 118-degree bits are more versatile and suitable for drilling a wide range of metals. 135-degree bits are designed for drilling hardened metals and provide better cutting efficiency.
Coating
Coatings such as titanium, black oxide, or cobalt are applied to drill bits to enhance their durability and performance. Titanium-coated bits offer increased resistance to wear and heat, while black oxide-coated bits provide better lubricity and corrosion resistance. Cobalt-coated bits combine the benefits of both titanium and black oxide coatings.
Flute Design
The flute design determines the chip removal efficiency. Spiral flutes are the most common and suitable for general-purpose drilling, efficiently evacuating metal chips. Straight flutes are ideal for drilling through thin metal sheets, while step flutes are for enlarging existing holes.
Cutting Edge
Drill bits can have a single cutting edge or double cutting edges. Single cutting-edge bits are suitable for softer metals, providing faster drilling. Double cutting-edge bits are more efficient for harder metals, offering improved chip evacuation.
Compatibility
Consider the drill type you will use – cordless or drill press – and ensure the drill bits are compatible with the specific drill type. Usually, it’s best to buy drill bits from the same brand as your drill.
Durability
Choose drill bits that are long-lasting and resistant to wear and tear. Look for bits made from high-quality materials and with appropriate coatings to ensure they can withstand frequent use.
Precision
Opt for drill bits that offer precision to achieve accurate drilling with minimal deviation. Look for bits with a sharp point and smooth cutting edges.
Heat resistance
Drilling metals generates heat. Select drill bits that can withstand high temperatures without losing their sharpness, ensuring they remain effective throughout your drilling tasks.
Chip removal
Efficient evacuation of metal chips during drilling is crucial to prevent clogging and maintain drilling performance. Look for drill bits with effective chip removal mechanisms, such as spiral flutes.
Speed and feed rate
Consider the recommended drilling speed and feed rate for the specific drill bits you are considering. Ensure they are suitable for your drilling applications, providing optimal performance without damaging the bits or workpiece.
Versatility
If you work with various metal types, choose drill bits that are versatile and compatible with multiple metal materials. This will save you from having to purchase different bits for different metals. The best drill bit sets will have drill bits designed for wood, metal, and stone.
Ease of use
Select drill bits that are easy to install and remove from the drill. Look for features such as a quick-change mechanism or a reliable chuck system for hassle-free operation.
Brand reputation
Consider purchasing drill bits from well-known and trusted brands in the market. These brands have a reputation for producing high-quality products that meet industry standards.
Price
While price is an important factor, it should not be the sole determinant of your decision. Look for drill bits that offer good value for money, balancing quality and affordability. But avoid drill bits that are too cheap, as these might not be the best quality.
