Why Professionals Choose Drill America’s Drill Bits
- Aerospace-Grade Standards: Many of our bits are manufactured according to National Aerospace Standard 907, featuring a 135° split point. This design provides a steady, productive drilling speed and significantly reduces "walking" at startup, allowing for pinpoint accuracy without the need for a center punch.
- Advanced Material Blends:
- M42 Cobalt: Our D/A Series M42 Cobalt bits are the gold standard for hardened metals. They hold an edge longer than standard M35 bits and allow for drilling speeds up to 30% faster than conventional high-speed steel.
- High-Speed Steel (HSS): Our HSS bits feature a black and gold oxide finish that increases surface hardness and resists corrosion, making them a reliable, cost-effective choice for general construction and metal fabrication.
- Versatility and Range: We offer one of the most comprehensive selections in the industry, including jobber-length, aircraft extension, reduced-shank, and extra-long bits. Whether you are performing deep-hole drilling or working in tight spaces, we have the specific geometry required for the task.
- Proven Durability: In independent professional testing, Drill America’s drill bits have demonstrated the ability to "melt through" hardened steel and stainless steel while maintaining their cutting edge, proving their value in high-intensity environments.
Key Benefits of Our Product Line
- Clean, Efficient Holes: Precision-ground flutes ensure superior chip evacuation, reducing heat buildup and extending the life of the tool.
- Self-Centering Tips: The 135-degree split point is engineered to bite into the material immediately, providing faster starts and more professional results.
- Industrial Strength: Trusted by tradesmen across industries—including HVAC, electrical, and steel fabrication—our bits are built to withstand the "violence" of high-torque impact drivers and heavy-duty drill presses alike.
From individual specialty bits to comprehensive 29-piece indexed sets, Inpro and Drill America deliver the consistency and performance you need to get the job done right the first time. Explore our full catalog to find the perfect edge for your next project.
