Product Specifications:
This heavy‑duty 36mm U drill is designed for large‑diameter holes in thick structural steel, excavator parts, and wind tower flanges. Operating at a conservative 1100‑1200 RPM, it reduces torque demand and vibration while maintaining a productive feed of 0.07‑0.08 mm/r. The 3D depth (108mm) covers most flange drilling applications. C32 shank ensures rigid clamping in heavy‑duty tool holders.
SPMG090408 inserts offer high edge strength, and the double helix coolant channels provide excellent heat dissipation at lower speeds. This U drill excels on machines with limited spindle power (e.g., 15‑20 HP) where high RPM is not possible. Typical applications include crane bases, excavator booms, press frames, and railway components. Because the insert geometry is optimized for interrupted cuts, it also performs well on cast iron surfaces with sand inclusions. For high‑volume production, consider upgrading to coated inserts (TiAlN) for extended tool life. Custom shank sizes (C40) and deeper depths (4D) are available for special orders. Trust this U drill for reliable, repeatable drilling in demanding environments.
