• Extensive stock of over 10,000 sizes covering thread diameters from 1 to 200 mm for all thread types.
• Custom dies tailored to specific workpiece materials and applications, including surface treatments when beneficial.
• Expertise in special and custom thread profiles.

Custom and Special Thread Cutting Dies

JBO efficiently develops and delivers client-specific special dies, including:

• Dies for hard-to-access threads and recutting stationary threads.
• Split dies with tangential adjusting screws for precise thread control.
• Custom dies for modified wood screw threads.
• Dies with projecting noses for threading in confined spaces.

High Performance Thread Cutting Dies – Detailed Features

• Brass and ECOBRASS Dies: Enlarged chip clearance holes prevent clogging; spiral entry for threads ≥ 3 mm; HSSE lapped dies for unleaded brass.
• Dies with Mounting Holes: Reduced inertia allows higher spindle speeds and longer tool life.
• Carbide Dies: For brass and gun metal threads >16 mm diameter; enable cutting speeds up to 100 m/min; 15-30 times longer life; support dry machining.
• HSS Dies (DIN EN Standard): Suitable for manual and machine use; effective for steel up to 800 N/mm² tensile strength and various materials.
• VA Dies: Designed for stainless, acid-resistant, quenched, tempered, and case-hardened steels up to 1,200 N/mm² and short-chipping aluminum alloys; HSSE, lapped, nitrided to prevent cold welding; fine chip formation due to increased clearance holes and extended chamfer.
• Bell Form Dies: Open chip spaces improve chip flow and coolant supply, especially near shoulders.
• Automatic Machine Dies: Increased number of enlarged clearance holes for longer life and higher thread quality.
• Long Life Dies: Similar application as VA dies but with maximum clearance holes and chamfer extension for extremely long tool life.
• Hexagon Dies: For recutting damaged threads or threading in difficult-to-reach areas.

High Performance Thread Rolling Dies

Boss pattern rolling dies (RB, RBV, RS, RSV) offer high load capacity with turnable and exchangeable rolls, suitable for demanding thread rolling applications.
