Norseman Drill & Tool Type 190-P Heavy-Duty Parabolic Flute Twist Drill Bit
Built for Extreme Performance
The Norseman Drill & Tool Type 190-P Heavy-Duty Parabolic Flute Twist Drill Bit is engineered for high-performance deep-hole drilling where speed, reliability, and durability are essential. Proudly made in the USA, this heavy-duty bit is crafted from premium high-speed steel (HSS), providing the strength, resilience, and consistency demanded by machinists, metalworkers, and industrial professionals.
Parabolic Flute Geometry
Superior Chip Evacuation for Deep Drilling
What makes the Type 190-P exceptional is its parabolic flute design, optimized to move large volumes of chips away from the cutting zone. This ensures:
-
Reduced heat buildup
-
Lower friction
-
Less chance of clogging or bit breakage
-
Smoother, faster drilling
This flute profile is especially effective when drilling softer or non-ferrous metals such as aluminum, brass, or copper—materials that often produce long, stringy chips that can bind standard drill bits.
135° Split Point for Fast, Accurate Starts
No Walking, No Pilot Hole
The 135° split point delivers immediate, accurate starts with minimal walking, eliminating the need for a pilot hole and increasing productivity. Combined with the bit’s heavy-duty web construction, this design improves torsional strength, reduces flexing, and enhances overall stability during demanding drilling operations.
Black & Gold Oxide Finish
Enhanced Wear Resistance and Cutting Efficiency
A durable black and gold oxide finish improves lubricity, increases wear resistance, and supports smoother cutting performance—critical for long-lasting tool life in high-speed or repetitive production environments.
