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 specifically designed for high-precision, high-performance drilling in demanding industrial and automotive environments. Made in the USA from premium high-speed steel (HSS), this drill bit delivers outstanding strength, heat resistance, and tool life—ideal for repetitive drilling in steel, cast iron, and aluminum.

What sets the Type 230 apart is its tanged shank, engineered for use in power-feed drill motors where secure engagement is essential.

This reduces walking and enhances efficiency—especially important when drilling into curved or hard surfaces. The letter size configuration allows for fine-tuned hole diameters beyond standard fractional or metric bits, offering flexibility in exact-fit applications.
