Product Specifications:
This 24.5mm indexable U drill is designed for general‑purpose drilling of medium carbon steel, alloy steel, and cast iron in job shop environments. Operating at 1700 to 1800 RPM with a moderate feed of 0.06 to 0.08 mm/r, it balances high metal removal rate and heat control, making it suitable for both manual and CNC machines. The 3D depth (73.5mm) handles common flange and housing holes, while the C25 shank ensures rigid clamping in standard holders.
SPMG07T308 inserts offer excellent edge strength for interrupted cuts – ideal for cast iron surfaces or weld‑scale removal. Double helix cooling flushes chips effectively, reducing downtime. Typical applications include pump housings, gearbox casings, agricultural implement frames, and structural steel columns. Compared to HSS drills, this U drill reduces cycle time by 3‑5× and eliminates pre‑spotting. Customize shank type, depth (2D‑5D), or insert grade for stainless or heat‑resistant alloys. For cost‑conscious workshops, this 24.5mm U drill delivers exceptional value and consistent hole accuracy.
