Premium Thread Cutting & Rolling Dies from JBO
Thread Cutting Dies
- JBO has been Europe’s leading manufacturer of high-performance thread cutting dies for over 100 years
- Many different geometries and tool materials available to find a perfect match for your application
- Available in HSS, HSS-E and solid carbide
- Available in round, round with 2-fixing holes, bell form and hexagon
- More than 10,000 sizes and types of dies in stock ranging in diameters from Ø1mm to 250mm
- Custom thread cutting dies available
HSS thread cutting dies to DIN EN standards
- for machine and manual use
- for cutting threads in steel up to approx. 800 N/mm² tensile strength
- different versions for cutting a wide range of materials
Thread cutting dies for automatics
- with greater number of enlarged clearance holes. Hence more cutting edges for longer die life and higher quality threads.
Thread cutting dies for brass
- Enlarged clearance holes prevent chips crowding, chamfer 1.25 P, with spiral entry (gun nose) for threads ≥ 3 mm diameter
Thread cutting dies for ECOBRASS
- for machining unleaded brass
– HSSE, lapped, chamfer 1.5 P
VA Thread cutting dies
For machining stainless, through hardening, surface hardening and other steels up to 1,200 N/mm² tensile strength, as well as aluminium alloys that produce short chips
- HSSE, lapped
- nitrided to prevent cold welding
- fine chips due to more clearance holes and thus more cutting edges, and the extension of the chamfer to 2 P
Long Life-High performance thread cutting dies
Field of application as for VA thread cutting dies
- HSSE (ASP 30) lapped
- nitrided to prevent cold welding
- very fine chips due to maximum number of clearance holes and thus still more cutting edges, and the extension of the chamfer to 2.25 P
- exceptionally long die life
Dies with two fixing holes
- The low inertia of the die holder permits higher spindle speeds and extends die life
Bell form thread cutting dies
- With open clearance holes for free chip flow and improved coolant supply, even when cutting threads close to shoulders
High-tech carbide thread cutting dies alternative carbide-tipped (brazed)
For machining brass and gun metal, available for thread diameters > approx. 16 mm
high cutting speeds up to 100 m/min
15 to 30 times longer die life
reduced die changing costs
less machine down time
advantages arising from dry machining
Hexagon die nuts
- For recutting and reclaiming damaged threads or for cutting threads in difficult locations
1/2-14 JBO Threading Die + Tschorn Floating Die Holder Test
Thread Rolling Dies
JBO Thread Rolling Dies
- JBO thread rolling dies offer non-cutting production of external threads
- These rolling dies offer a cost-effective alternative to commercially available rolling heads
- Threads produced by thread rolling are significantly stronger than threads that have been cut
- Thread rolling produces no chips
- Rolling produces excellent surface finish on the threads
