JBO Thread Guages, Thread Milling Cutters and Thread Cutting Dies

High Performance Thread Cutting Dies
JBO manufacture carbide dies for threads approx. 16mm dia. upwards and for pitches from 1 to 2.5 mm or 11 to 24 tpi to DIN EN specifications. Bell form type and special size dies to suit customer requirements can also be supplied.

JBO solid carbide dies cut the cost of producing threaded parts appreciably.

JBO solid carbide thread cutting dies last 15 - 30 times longer than HSS dies.










JBO Hexagonal Die Nuts
Include:
Metric ISO-Thread
Metric fine ISO-Thread
British Standard Whitworth coarse thread
British Standard pipe thread
BSF-thread
UNC thread
UNF thread
NPT- thread
British Standard pipe thread taper







JBO High Performance Thread Rolling Dies
Materals suitable for thread rolling
JBO thread rolling dies are suitable for materials that can be cold formed and that have a minimum elongation of approx. 8% coupled with a tensile strength up to approx. 900N/mm square.

JBO thread rolling dies have thread rolls with lead profile
A more accurate thread profile and a more accurate pitch are thereby achieved. With materials that are difficult to form, the lead profile also extends the life of the thread rolls.









JBO Solid Carbide Thread Milling Cutters
Types include:

-Solid Carbide Thread Milling Cutters for Internal Threads
-Solid Carbide Thread Milling Cutters for Internal and External Threads
-BGF Solid Carbide Combined Drilling and thread Milling Tools for Internal Threads

-Solid Carbide Thread Milling Cutters with Coolant Channels on Shank or Coolant Holes in Flutes
-Shell Type Milling Cutters
-Shell Type Thread Milling Cutters











JBO Combination Tools
Combination Tools for Spotfacing, countersinking, counterboring and thread milling operations.


















JBO Precision Thread Guages
JBO Thread guages and inspection machine mountings made to drawings or specially designed.

Inspection machine mounting for checking the radial runout of external threads. Manufacturing tolerance for radial and axial runout less than or equal to 0.01mm. HSS TiCN coated GO plug guage with adjustable screw.

NOT GO plug guage for checking deep seated threads

Thread plug limit guage with adjustable depth stop for ensuring the required thread depth.

Thread plug limit guage with increased stem diameter for checking small, deep seated threads.

GO thread plug guage with hexagon shank for quick mounting in inspection machine.

HSS TiCN coated GO plug guages with dirt collecting groove for mechanised inspection.
The TiCN (Balzers) coated thread guages are extremely wear resistant and have excellent anti-friction properties. Guage life is thereby increased about ten-fold.
