When precision is the difference between a successful assembly and a ruined workpiece, professional machinists turn to specialized tooling. Amana drill bits are widely recognized in the industry for their high-performance carbide engineering, designed specifically to handle the rigors of high-speed machining and demanding industrial environments. Unlike standard consumer-grade bits found in general hardware sets, these tools are engineered for specific material interactions, heat resistance, and dimensional accuracy. Whether you are working with hardened steels, aerospace-grade alloys, or non-ferrous metals, selecting the right bit from this lineup requires an understanding of geometry, coating technology, and substrate quality.

It is a versatile collection that works just as well in a handheld drill as it does on a drill press, making it a reliable staple for any workshop.
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.

A Guide to Selecting the Best amana drill bits
Material Compatibility and Substrate Selection
The most critical decision factor when selecting an Amana drill bit is the material you intend to pierce. Because these bits are often manufactured from micrograin carbide, they offer incredible hardness but can be brittle if used incorrectly. For soft materials like aluminum or plastics, you should look for bits with high-helix angles and polished flutes to facilitate rapid chip evacuation and prevent material buildup. Conversely, when drilling through stainless steel or titanium, you need bits designed for high heat resistance. These bits often feature specialized geometries that reduce friction and prevent the tool from work-hardening the material during the drilling process. Always match the bit's intended application to your specific workpiece to avoid premature tool failure.
Coating Technology and Surface Treatment
A significant portion of a premium drill bit's performance is derived from its coating. Amana utilizes various advanced coatings to extend tool life and improve cutting efficiency. Titanium Nitride (TiN) is a common choice for general-purpose applications, providing a hard surface that resists wear. However, for high-temperature operations, coatings like Titanium Aluminum Nitride (TiAlN) are superior because they form a protective layer when heated, actually becoming more effective as the cutting temperature rises. If you are working in a dry machining environment, prioritize coatings that offer high thermal stability. If you are using coolant, you may have more flexibility, but a high-quality coating will still significantly increase the number of holes you can drill before the cutting edge dulls.
Geometry and Flute Design
The geometry of the drill bit determines how it handles chip evacuation and how it enters the material. For deep-hole drilling, look for bits with optimized flute depths that allow chips to travel out of the hole without clogging. A clogged flute leads to heat buildup, which is the primary killer of carbide tools. Additionally, pay attention to the point angle. A standard 118-degree point is versatile, but a 135-degree split point is often preferred for harder materials as it reduces the pressure required to start the hole and minimizes 'walking' on the surface of the workpiece. Split point geometries are particularly useful for precision work where you cannot afford a wandering drill tip.
Shank Type and Tool Holding
Before finalizing your purchase, ensure the shank type is compatible with your existing tool holders. Most high-performance bits in this category utilize a straight shank or a tapered shank designed for high-precision collets. If you are using a CNC machine, ensure the tolerances of the shank meet your machine's requirements for runout. High runout—where the bit wobbles slightly in the holder—will cause uneven wear and poor hole quality. For the best results, pair these high-end bits with high-quality, precision-ground tool holders to ensure the accuracy of the bit is fully realized during operation.
