GY-HSJ HSS Parallel Shank Long Drills Ground Flute

As per IS: 5102

HSS Straight Shank Long Drills. Engineered for industrial-grade performance, these drills feature an extended flute length specifically designed for deep-hole drilling and applications involving drill bushings.

Manufactured from premium High-Speed Steel (HSS) and processed with advanced heat-treatment technology, these bits provide the consistent hardness and wear resistance required for high-volume production environments.

Key Features

  • Extended Reach: The long-flute design ensures efficient chip evacuation when drilling deep holes, preventing clogging and overheating.
  • Industrial Precision: Produced on advanced CNC machines to guarantee accurate geometry and strict adherence to international standards.
  • Enhanced Tool Life: Optimized for a higher “holes-per-drill” ratio, significantly reducing operational costs and downtime.
  • Versatile Point Angles: Available in 118° and 135° point angles to suit various material hardness levels and self-centering requirements.
Technical Specifications
  • Standards: IS 5102 / DIN 340 / BS 328 / ISO.
  • Shank Type: Straight Shank.
  • Applications: Ideal for use in Automobile manufacturing, Machine Tool production, CNC shops, and VMC machining centers.
