SPMG-DG

ZANHO SPMG-DG series is a high-performance indexable drill insert specifically designed for difficult drilling operations in sticky materials such as stainless steel, titanium, and high-temperature alloys. Featuring a large positive rake angle and a specialized DG guide cavity, it significantly reduces drilling resistance and ensures stable chip curling and evacuation. With its robust 4-edge square geometry, it delivers exceptional cost-efficiency and reliable edge integrity for conventional shallow-hole CNC drilling.

Description

Key Performance & Features

  • Sticky Material Specialist: Engineered to solve high cutting resistance and chip evacuation issues in stainless steel, titanium, and nickel-based alloys.
  • Large Positive Rake Geometry: Reduces drilling load and suppresses work hardening, ensuring stable performance even on lower-rigidity machines.
  • DG Chipbreaker Technology: Specialized flow guide cavity fragments wide chips into short segments, preventing clogging in the drill body flutes.
  • Reinforced Edge Strength: Controlled negative land on the cutting edge balances sharpness with impact resistance, protecting the tip during U-drill entry.
  • Universal Material Application: Highly versatile across Carbon Steel (P), Stainless Steel (M), and Cast Iron (K), optimizing tool management.
