Deep hole drilling has long presented one of the greatest challenges in metalworking—chip evacuation, tool deflection, and heat buildup often stand between the operator and a successful operation. To address these challenges, MSK introduces the HSSCO Deep Hole Parabolic Fluid Twist Drill, a precision-designed solution aimed at redefining stability, accuracy, and durability in deep hole applications.
Built for professionals who refuse to compromise on quality, this new line combines advanced material science with a geometry optimized specifically for high-aspect-ratio drilling. Whether in mold making, automotive manufacturing, or general engineering, these bits deliver performance where conventional drills fall short.
Uncompromised Stability for Deep Hole Drilling
The defining feature of this series lies in its stability principle designed for deep hole drilling. Each drill bit incorporates a specialized flute geometry and a reinforced core, ensuring that the tool maintains its trajectory even at significant depths. The design integrates sharp teeth with an internal folding edge, a structural innovation that effectively improves stability during deep hole drilling by reducing vibration and preventing wandering upon entry. This results in straighter holes and significantly reduced tool stress, even when drilling into tough materials such as stainless steel, hardened alloys, and tool steel.
The Parabolic Advantage
Classified as premium Hss Parabolic-Flute Drill Bits, this set leverages the parabolic flute profile to overcome the primary limitation of standard twist drills: chip clearance. Unlike conventional flutes that pinch chips in deep holes, the wide, open parabolic shape actively evacuates swarf upward and away from the cutting zone. This ensures:
Smooth drilling with consistent feed rates and minimal interruption
High durability of the drill, as reduced heat and friction directly translate to extended tool life
Superior hole accuracy, with tight tolerances maintained across the entire depth of cut
For operations requiring a reliable Parabolic Drill, this geometry offers a clear performance advantage, particularly in hole depths exceeding four times the drill diameter.
Engineered for Longevity and Precision
Crafted from HSSCO (High-Speed Steel with Cobalt), these drill bits exhibit exceptional red hardness, allowing them to retain cutting edge integrity at elevated temperatures. The combination of cobalt content and the parabolic flute architecture makes these tools ideal for both manual machining centers and CNC applications where consistency is critical.
The surface finish is optimized to reduce friction further, promoting smoother chip flow and preventing material adhesion—a common failure point in softer, gummier metals like aluminum and copper alloys.
Available Now
The HSSCO Deep Hole Parabolic Flute Twist Drill Bit set is now available for worldwide shipping through MSK. Offered in a range of standard metric and imperial sizes, each bit is manufactured to exacting standards to meet the needs of precision engineers and maintenance professionals alike.
