How to choose
Material Compatibility
Select drill bits based on the specific material you intend to penetrate. Some options in this category are optimized for wood and plastic, utilizing brad point designs for tear-free holes or roll-forged HSS for general use. Other specialized bits, such as the hex shank masonry bits, are engineered specifically for concrete, brick, and stone. Ensure the bit material, such as High-Speed Steel (HSS), matches the hardness of your workpiece to prevent premature dulling or breakage. Always verify the manufacturer's intended application before selecting a bit to ensure it can handle the density and abrasive nature of your target material, whether it is PVC, iron, or masonry.
Shank Design
The shank configuration determines how the bit interfaces with your drill chuck. Universal straight shanks are common for standard drill presses and handheld power drills, offering broad compatibility for various woodworking and metalworking tasks. Alternatively, hex shank designs provide a secure grip for impact drivers or quick-change chuck systems, which is particularly beneficial for masonry bits. When choosing, consider your existing tool inventory to ensure the shank type matches your chuck capacity. Improper shank selection can lead to bit slippage or instability during operation, affecting the accuracy and quality of your drilled holes across different project requirements.
Sizing and Precision
Drill bit sizing is categorized in multiple ways, including metric dimensions, wire gauge, and fractional measurements. For high-accuracy woodworking, a specific 9mm brad point bit is available. If your project requires precision drilling for electrical or mechanical assemblies, wire gauge numbered bits like the No. 9 size offer exact diameters for specific hole requirements. Projects involving standard construction materials may be better served by fractional sizes such as the 9/32-inch masonry bit. Always check the specific measurement system required by your project plans to avoid loose fits or oversized holes that could compromise the integrity of your fasteners or assemblies.
Bit Geometry and Point Style
The point style of a drill bit significantly influences how it starts and finishes a hole. Brad point bits feature a sharp center spur and beveled edges, designed to minimize tear-out in wood for cleaner results. Split point designs, often found on HSS bits, help prevent the bit from walking or wandering across the surface when starting, which is essential for working on harder materials like metal. Consider whether your project prioritizes hole entry precision, surface finish, or structural durability. Matching the geometry to the surface type ensures efficient chip evacuation and reduces the likelihood of the bit binding during the drilling process.
Quantity and Packaging
Consider the volume of work and the potential for bit wear when selecting your set size. Some options are sold as single-size packs of 12 for high-frequency use, while others are available in 3-pack or 5-pack configurations for smaller tasks. Sets containing a range of sizes, such as the 8-piece metric set, offer versatility for those frequently switching between different hole diameters. Think about your storage needs as well; indexed cases help keep bits organized and prevent loss, whereas bulk packs may be more economical for professional shops that expect to replace bits regularly due to constant use or accidental breakage.
Frequently asked questions
Can I use the 9/32-inch hex shank bits on standard wood?
These specific bits are marketed as hammer drill masonry drill bits, designed for concrete, cement, brick, and stone. While a masonry bit might physically enter wood, it is not optimized for that material. Using masonry bits on wood may result in rough hole quality, heat buildup, or excessive splintering compared to bits specifically engineered for woodworking, such as brad point or standard HSS twist bits.
What is the benefit of a brad point drill bit?
Brad point drill bits are specifically designed for woodworking. The central spur helps position the bit accurately on the workpiece, preventing it from wandering when you start the hole. Additionally, the beveled edges around the circumference of the bit cut the wood fibers cleanly before the main body of the bit passes through, which results in smooth, tear-free holes compared to standard twist bits.
Are the HSS bits suitable for drilling into hardened steel?
The available HSS drill bits are identified for use on materials like iron, PVC, and aluminum. While High-Speed Steel is durable, always check the specific product rating and manufacturer recommendations regarding material hardness. If you are working with extremely hardened steel or specialized alloys, ensure the bit is rated for those specific metal applications to avoid rapid dulling or fracturing of the drill bit tip.
What does 'No. 9' mean in the context of the MAXTOOL jobber length drills?
In this context, 'No. 9' refers to a specific size designation within the wire gauge system for drill bits. This is a standard sizing method used for precision work, where the diameter of the bit is determined by its position in the gauge scale rather than a simple metric or fractional measurement. Always verify the decimal equivalent of the gauge size to ensure it matches your specific project requirements.
How do I ensure my bits stay sharp longer?
To maintain the longevity of your drill bits, avoid forcing them into the material, which can cause heat buildup and premature wear. Use the correct speed for the material you are drilling and ensure the bit is properly aligned. For HSS bits, using a cutting fluid when drilling into metals like iron or aluminum can help reduce friction and heat, which preserves the cutting edge of the bit over time.
Bottom line
For projects requiring specific sizing and performance, the product lineup offers distinct advantages based on application. The Drill America #9 HSS split point bits are the strongest choice for users needing a reliable, high-volume supply for metalwork, thanks to their 12-pack quantity and split-point geometry. For woodworking precision, the Premium Brad Point bit stands out for its ability to produce clean, tear-free holes. If you require versatility, the 8-piece metric HSS set provides a range of sizes for various materials like PVC and aluminum. Finally, the hex shank masonry bits are the clear winner for concrete and brick applications, offering the necessary durability for tough, abrasive surfaces where standard twist bits would quickly fail.
Deciding which bit to choose depends primarily on your specific material and hole diameter requirements. If you are drilling wood, prioritize the brad point design for finish quality. For metal or general-purpose tasks, select an HSS set that covers your needed metric or gauge sizes. If your application involves masonry or impact-driven tools, the hex shank masonry bits are essential. Always evaluate whether you need a single-size bulk pack for repetitive tasks or a multi-size set for varied projects. By matching the bit material, shank type, and geometry to the specific demands of your workpiece, you ensure better results and longer tool life.
