FANAR DIE M20x1 HSS800F Round Threading Die, Metric M20 x 1.0 mm, High-Speed Steel, Right-Hand, 6g

The FANAR DIE M20x1 HSS800F stands apart from generic round threading dies by pairing a high-speed steel 800F grade with a bright, uncoated finish—an uncommon combination that resists edge chipping while reducing friction for cleaner threads. Engineered to DIN 223 (EN 22568), it fits standard 45 mm die stocks and delivers a tolerance class of 6g on M20 x 1.0 mm external threads, making it a dependable choice for maintenance shops and machine builders alike.

Highlights

• Metric thread form: M20 x 1.0 mm, right-hand cutting direction
• High-speed steel (HSS) construction, 800F grade for enhanced durability
• Manufactured to DIN 223 (EN 22568) for reliable die stock compatibility
• Tolerance class 6g ensures threads meet standard fit requirements
• Bright finish for smooth chip flow and reduced galling
• Outer diameter 45 mm, thickness 14 mm – fits standard 45 mm die stocks

In daily use

This die is intended for manual or machine threading of external threads on rods, bolts, or shafts. It works well on steel, cast iron, and non-ferrous metals. For best results, use a suitable cutting oil and start with a chamfered workpiece. The die should be held in a die stock with a 45 mm bore; the central hole is designed to guide the workpiece and produce a straight, accurate thread. Because the die is right-hand, it cuts threads that tighten clockwise.
