Precision Performance: Norseman Drill & Tool Letter Sizes Type 240-F Twist Drill Bit
Engineered for Accuracy, Speed, and Multi-Material Versatility
The Norseman Drill & Tool Letter Sizes Type 240-F Twist Drill Bit is a premium-choice drilling solution for professionals who demand accuracy, reliability, and long-lasting performance. Proudly made in the USA, this high-speed steel (HSS) drill bit is engineered for strength, durability, and heat resistance—making it an exceptional tool for drilling metal, wood, plastics, and other low-tensile materials.
High Helix Performance for Smooth, Efficient Drilling
The Type 240-F features a fast spiral (high helix) flute design that excels at removing chips quickly and cleanly. This helps maintain cooler drilling temperatures, reduces clogging, and improves drilling efficiency—especially in soft or non-ferrous materials such as aluminum, zinc, copper, brass, and bronze. The high helix geometry also produces cleaner hole finishes, even in deeper drilling applications.
Precision Starts with a 135° Split Point
Equipped with a 135° split-point tip, this drill bit provides fast, accurate starts without walking, even on curved or hard surfaces. This self-centering design reduces thrust pressure and ensures consistent hole accuracy—critical when working with letter-sized drill dimensions that require exact tolerances.
Built for Professional Durability
Each bit is manufactured from premium HSS and finished with black and gold oxide, enhancing corrosion resistance, lubricity, and chip flow. Norseman’s precision grinding and rigorous quality control ensure excellent balance, reduced vibration, and extended tool life—protecting both the bit and your equipment.
