This Indian Workshop Handbook eBook from 3D-LABS is written for engineers and students who want a clear, practical reference they can apply immediately.
Indian Workshop Handbook — Threads, Fits, Cutting Data is a practical desk reference covering Indian and international thread standards, IS 919/SP 46 limits and fits, cutting speed and feed tables for common Indian workpiece materials, and workshop calculations. Written for workshop engineers, toolroom machinists, and production managers.
What thread standards are covered?
IS 1362:1993 (ISO metric coarse M1 to M300), IS 4218 Part 1 (fine series), IS 2643 (BSP/G pipe threads), IS 2108 (NPT tapered pipe threads), and IS 4218 Part 3 (trapezoidal threads). Data tables include pitch, major/minor/pitch diameter limits per 6g bolts and 6H nuts tolerance classes, and spanner/socket sizes.
What limits and fits data does this handbook provide?
IS 919 Part 1 and SP 46:2003 hole-basis preferred fits: H7/g6 (close sliding), H8/f7 (sliding), H7/k6 (transition), H7/p6 (press fit). Clearance ranges in micrometres, application examples (bearing housing, shaft seal, press-fit pin), and inspection methods (plug gauge, snap gauge). Nominal sizes 1 mm to 500 mm.
What cutting data is provided for Indian materials?
Carbide tooling cutting speeds (m/min): IS 2062 E250 structural steel 120-160, SS 304/316 stainless 80-100, IS 210 FG200 grey cast iron 100-140, IS 733 HE30 aluminium 300-500 m/min. IS 1570 EN31 bearing steel at HRC 60 = 30-50 m/min. Feed tables for turning, milling, and drilling (118-degree point for standard steel, 135-degree for stainless steel).
