Product Specifications:
This 18.5mm indexable U drill is engineered for high‑speed drilling in thin‑walled carbon steel components, general machinery parts, and automotive brackets. With a 3D depth capacity (55.5mm) and C25 straight shank, it fits standard 25mm tool holders on CNC lathes and machining centers. The recommended cutting parameters – 2100 to 2300 RPM with a feed rate of 0.05 to 0.08 mm/r – deliver rapid cycle times, reducing production cost by up to 40% compared to conventional twist drills. Double helix internal cooling holes direct coolant precisely to the cutting edge, preventing chip packing even at high speeds.
The SPMG060204 inserts feature two economical cutting edges and provide excellent wear resistance in material up to 250 HB. Typical applications include engine brackets, flange holes, structural steel channels, and farm equipment frames. This U drill eliminates the need for center drilling, saving setup time. For job shops and high‑volume production lines, this 18.5mm U drill offers consistent hole quality and long tool life. Custom shank diameters and 2D/4D depths are available for OEM orders.
