Norseman Drill & Tool Letter Sizes Type 230 Twist Drill Bit
Automotive-Grade Performance for Precision Drilling
The Norseman Drill & Tool Letter Sizes Type 230 Twist Drill Bit is engineered for high-precision, heavy-duty drilling in automotive, industrial, and production environments. Proudly made in the USA from premium high-speed steel (HSS), this drill bit delivers exceptional strength, heat resistance, and long-lasting durability—making it ideal for repetitive drilling in steel, cast iron, aluminum, and other common automotive alloys.
Designed for Power-Feed Drilling Systems
What truly sets the Type 230 series apart is its tanged shank, specifically designed for use in power-feed drill motors. This specialized shank ensures secure, slip-free engagement under high torque, providing consistent drilling performance in assembly lines, engine repair shops, and heavy equipment maintenance operations. The tang design guarantees optimal transfer of power, reducing downtime and improving overall productivity.
Precision Starts with a 135° Split Point
Featuring a 135° split point, the Type 230 Letter Size drill bit delivers fast, accurate starts without the need for a pilot hole. This geometry minimizes walking and ensures precise hole placement, even on curved, angled, or hardened surfaces. The result is cleaner drilling, reduced operator effort, and enhanced drilling efficiency.
Letter Sizes for Fine-Tuned Accuracy
Letter-sized drill bits provide incremental precision beyond fractional or metric specifications, making them ideal for applications that require exact hole diameters. Whether fitting specialty fasteners, engineering components, or repair hardware, the Type 230 delivers the accuracy professionals rely on.
