Reliable Precision with Enhanced Wear Resistance and Lubricity
The Norseman Drill & Tool Letter Sizes Type 115 Twist Drill Bit is engineered for professionals who demand consistent accuracy, durability, and smooth drilling performance across a wide range of materials. Proudly made in the USA, this high-quality drill bit delivers the dependable results that machinists, fabricators, and maintenance teams rely on every day.
Built for Strength, Versatility, and Longevity
Manufactured from premium high-speed steel (HSS), the Type 115 offers outstanding toughness and cutting efficiency. It performs exceptionally well in steel, aluminum, brass, wood, and plastics, making it a versatile choice for general-purpose drilling. This bit maintains sharpness under frequent use, providing long-lasting precision and clean hole finishes.
Enhanced Performance with Black Oxide Finish
A key performance advantage of the Type 115 is its black oxide surface treatment, which significantly increases wear resistance and improves lubricity. The coating reduces friction and heat buildup, allowing the bit to run cooler while extending its service life. Improved chip evacuation results in smoother cutting and greater efficiency, making it ideal for both high-speed and manual drilling applications.
Precision-Ground for Accurate, Controlled Drilling
Featuring a 118° standard point geometry, this drill bit offers controlled starts, reduced walking, and precise hole placement. The precision-ground flutes ensure balanced operation, smoother chip flow, and consistent drilling performance. Available in letter-size increments, the Type 115 provides fine-tuned accuracy for applications requiring precise hole sizing.
