When standard-length drill bits fail to reach the depths required for deep-hole drilling, specialized straight long drill bits become indispensable. Whether you are working on automotive repairs, heavy machinery maintenance, or deep woodworking projects, these bits are engineered to maintain stability and precision far beyond the reach of a typical twist bit. However, because the increased length introduces significant risks regarding deflection, breakage, and heat buildup, selecting the right bit requires more than just measuring the required depth. You must consider material compatibility, flute geometry, and the structural integrity of the shank to ensure a successful bore.

Most people assume a long drill bit will wander or flex uncontrollably, but the SOMADA ship auger uses a solid center design to maintain surprising rigidity. I found that the 1/2-inch diameter paired with the 3/8-inch hex shank makes it incredibly easy to drive into tough materials without the bit slipping in the chuck. Whether you are boring into railroad ties, landscape timber, or even tree stumps, the self-feeding coarse screw point does most of the heavy lifting for you. The single-spur cutting edge is a standout, as it scribes the hole circumference to ensure a clean, smooth finish rather than a jagged mess.

12 inch Extra Long Brad Point Drill Bit Set with 7 Total Drill Bits • Ideal for Wood • PVC • Resin • Composite • MDF and Drywall (Sheet Rock) Material...
- Sometimes bigger is better and when it comes to drilling or boring into thick material, bigger is definitely better. Introducing the Fulton high speed steel extra long brad point drill bit set. Each bit measures around 12 inches in total length to provide you with enough drilling length to tackle most any project you can throw at them.
- Many times when working around the house or out on the job site, we come across a situation where we need to drill through thicker material like a 6 x 6 or 4 x 4 when building things like an privacy fence or even rough building applications. These Fulton extra long brad point drill bits are perfect for these situations!
- Made from high speed steel, these bits are ideal for many different project types and materials. Drill into MDF, 4 x 4’s, 6 x 6’s, PVC, Resin’s, Composites, Plywood and more. Since each bit has a sharp (brad point) tip, it is recommended that you do NOT use these bits to drill into metal objects.
- Brad Point drill bits are specifically designed for better hole location accuracy. The sharp point on the tip allows you to precisely locate your mark with the bit and with a little pressure, the bit won’t slip or walk as you initiate the drilling process. This makes brad point drill bits excellent for woodworkers, carpenters, DIYer’s and more!
- Each high speed steel bit is made in the auger spiral style. The reason for this is to help clear build up and chips as you drill. When using any drill bit and especially longer bits like these, you must always clear the bit by pulling it back out of the hole to discharge the build up and chips. This helps reduce friction and the overall stress on the bit producing a much smoother hole and overall drilling experience.

The dark, matte finish of this black oxide-treated bit immediately signals it is built for more than just light hobby work. When you're drilling deep into thick iron or steel, that extra 18-inch reach is a total lifesaver for accessing recessed areas that standard bits simply can't touch. I found the high-speed steel construction provides that essential balance of hardness and toughness needed to prevent premature wear during long runs. The spiral flutes do a great job of pulling chips up and out of the hole, which keeps the cutting edge from clogging up mid-drill. Because it features a standard round shank, it slides into almost any toolholding system you already have in your shop without any compatibility headaches.

Most contractors assume a drill bit is just a piece of shaped metal, but the MAGBIT bellhanger bit proves that geometry is actually a performance multiplier. The 82-degree point is the real hero here, preventing that frustrating bit-walk and allowing for much faster, more accurate starts in tough materials. I was particularly impressed by the thoughtful engineering of the fish eye hole near the flute tips. It makes pulling wire through a finished hole significantly less of a headache. Since this is high carbon steel, it feels substantial and built for the rigors of professional electrical work. Even the inclusion of recesses for extension set screws on larger sizes shows that this tool was designed by people who actually spend time on a job site.
A Guide to Selecting the Best Straight Long Drill Bits
Material Composition and Hardness
The first decision factor is the substrate of the bit. For general-purpose drilling in softwoods or plastics, high-carbon steel is often sufficient and cost-effective. However, for professional-grade applications involving metals, you must look for High-Speed Steel (HSS) or Cobalt alloys. Cobalt bits are particularly vital for long-reach applications because they retain their hardness at much higher temperatures. As a long bit travels deeper into a workpiece, chip evacuation becomes difficult, leading to friction and heat. A cobalt bit can withstand this thermal stress without losing its cutting edge.
Flute Design and Chip Evacuation
In long-reach drilling, the greatest enemy is 'chip packing.' If the metal or wood shavings cannot escape the deep hole, they will clog the flutes, causing the bit to seize, overheat, or snap. Look for bits with deep, wide flutes that allow for efficient debris removal. Some specialized bits feature variable flute spacing or specialized helix angles designed to pull material upward more aggressively. If you are drilling through thick, gummy materials like aluminum, a bit with a more aggressive spiral will significantly reduce the risk of a catastrophic stall.
Length-to-Diameter Ratio and Rigidity
The 'aspect ratio'—the relationship between the bit's length and its diameter—is critical for stability. The longer the bit relative to its thickness, the more prone it is to 'wandering' or deflecting off the center axis. To combat this, look for bits that feature a reinforced shank or a thicker web core. A thicker core provides the structural rigidity necessary to prevent the bit from bending under lateral pressure. If your application requires extreme depth, consider whether you need a single-piece long bit or a modular system that allows for extensions, though a single continuous piece of steel will always offer superior concentricity.
Point Geometry and Centering
Because long bits are prone to walking across the surface of a workpiece before they bite, the tip geometry is paramount. A standard 118-degree point is common for general use, but a 135-degree split point is often superior for long bits. The split point design helps the bit self-center more effectively, reducing the need for a pilot hole and minimizing the initial deflection that can ruin a deep-bore project. For precision metalwork, a split point ensures that the bit stays true to the intended axis from the very first rotation.
