GY-HSR HSS Tapper Shank Regular

As per IS: 5103

Our HSS Taper Shank Drills are manufactured using premium-grade High-Speed Steel and advanced heat treatment technology. This ensures a robust tool life, allowing for more holes per drill and significantly reducing operational costs. Each unit is produced on high-precision CNC machines to guarantee accurate geometry and reliable performance in every use.

Key Features

  • Industrial Standard Compliance: Designed and manufactured to meet rigorous IS 5103, DIN 345, and BS 328 standards.
  • Precision Geometry: CNC-machined for consistent flute shapes and cutting edges, ensuring smooth chip evacuation.
  • Universal Fit: Features a standard Morse Taper (MT1 to MT5) to fit securely into American Standard tapered holders and spindles.
  • Optimized Point Angles: Available in 118° and 135° point angles to suit various material hardness levels and minimize “walking” during starts.
  • Enhanced Durability: Advanced heat treatment provides uniform hardness, preventing premature wear and breakage under high-torque conditions.
Technical Specifications
  • Standards: DIN 345 / IS 5103 / BS 328
  • Shank Type: Morse Taper (MT1 – MT5)
