EXTRACUT HSS Turbomax Drill Bits an innovative multi-flute turbomax design that combines the versatility of twist drills with the efficiency of end mills. The unique flute geometry delivers faster penetration rates, superior hole roundness, and exceptional surface finish — making them the go-to choice for high-productivity drilling operations where cycle time reduction is paramount.
Key Features
- Turbomax Flute Geometry — Optimized multi-flute profile with variable helix angle reduces cutting forces by 25% while increasing material removal rate compared to standard 2-flute designs.
- Enhanced Chip Evacuation — Wider flute gullets and optimized rake angles prevent chip packing in deep-hole applications, reducing heat buildup and tool breakage.
- Improved Hole Quality — Produces holes with superior roundness (IT10–IT11 tolerance) and surface finish (Ra 1.6–3.2 μm), often eliminating the need for secondary reaming.
- Higher Feed Rates — Geometry supports 30–50% higher feed rates than equivalent-diameter standard twist drills without sacrificing tool life.
- M2/M35 HSS Options — Available in both standard M2 and cobalt-alloyed M35 grades for varying material difficulty levels.
- Versatile Application Range — Effective across steel, stainless steel, aluminum, cast iron, and non-ferrous alloys with a single tool design.
Applications
High-volume production drilling in CNC machining centers, transfer lines, and automated drilling stations where cycle time reduction directly impacts throughput. Particularly effective in automotive parts manufacturing, hydraulic component production, and general job-shop environments requiring fast, clean holes with minimal post-processing.
