Hardened Tungsten Carbide Tips (TCT): Ultra-sharp micro-grain carbide cutting edges maintain razor sharpness longer than standard high-speed steel, resisting dulling during repetitive runs.
Exact 35 mm Cup Hinge Sizing: Precision-machined 35 mm diameter produces clean, snug pocket recesses for all standard European auto hinges ("Auto Kabja") without sloppy tolerance fit.
Tear-Free Edge Shearing: Radial perimeter cutting teeth slice through surface laminates, acrylics, and natural veneers cleanly before clearing waste, eliminating rim breakout.
Heat & Friction-Resistant Architecture: High-clearance flutes facilitate rapid wood chip extraction and dissipate operational heat build-up during continuous drill-press production.
Universal Drill Chuck Shank: Easily mounts into standard 10 mm and 13 mm chucks on corded drills, cordless drill-drivers, benchtop drill presses, and boring machines in workshops across Nepal.
