YG1 Sprocket Cutter ANSI 08B - 12.7 mm Pitch HSS

Sprocket cutter for cutting roller-chain sprockets to ANSI 08B / ISO 06B. Profile generates the correct seating radius for a 12.7 mm-pitch chain (No. 40 / 1/2-inch).

Features

• Chain Standard: ANSI 08B / ISO 06B (DIN 8187)

How to Use

• Generate sprocket teeth on a horizontal mill or hob; index per tooth count.
• Match the cutter to the chain class — sprockets cut for 08B will not seat 10B chain correctly.
• Always finish with a chamfer pass on tooth flanks for smooth chain entry.
