Premium Thread Milling Cutters From JBO
Premium Thread Milling Cutters from JBO
Features
- Threads to different tolerance classes can be produced with the same cutter
- Tool breakage typically does not entail scrapping of the workpiece
- Shorter cycle times
- Fantastic surface finishes on the threads since entire thread form is being cut with the thread mill
- Thread milling produces shorter chips which alleviates chip control issues you typically see when tapping
- Threads can be cut down to the bottom of blind holes
- Universally Applicable
(Steels, Cast Iron, Non-Ferrous Metals,
Nickel Alloys) - Low Vibration
- Variable Spiral Pitch
- Left Hand Spiral Flutes
- Right Hand Cutting
- Long Tool Life
GF / GF SHARK:
Solid Carbide Thread Mill
(2xD & 2.5xD)
Universal high performance tool with left-hand spiral flutes, variable spiral pitches and a large number of teeth for high surface quality and outstanding tool life, for cost effective production of internal screw threads.
GFT SHARK:
Solid Carbide Thread Mill with 3 Rings of Teeth
(3xD)
Universally applicable high-performance tool with the technological properties of
GF SHARK for the production of internal threads from M 1.2 to M 20, UNC No.1 to UNC 1/4“ and UNF No.2 to UNF 1/4“.
GFM SHARK:
Solid Carbide Wide Range Thread Mill
Universal high performance tool for cutting a wide range of thread-Ø with an identical pitch. Left-hand spiral flutes, unequal spiral pitches and a large number of teeth for high surface quality and outstanding tool life.
GFS:
Solid Carbide Thread Mill with Chamfering Capability
(2xD & 2.5xD)
Universal tool for cutting internal screw threads. Increased productivity resulting from combined thread milling and chamfering in a single machining cycle without tool changing.
GFH:
Solid Carbide Thread Mill for Hard Materials
Special version of GF cutter for cutting internal screw threads in tempered and hardened steels in the 54-63 HRC range.
GFT-H:
Solid Carbide Thread Mill with 3 Rings of Teeth for Hard Materials
Special version of GFT cutter for cutting internal threads ranging from M 2 to M 8 in tempered and hardened steels in the 54-63 HRC range.
GFE:
Solid Carbide Thread Mill with Single Ring of Teeth
Universal tool for cutting internal threads ranging from M 1 to M 3.5.
BGF:
Solid Carbide Drill Thread Mill (Aluminum)
Combines drilling with thread milling and chamfering in the production of internal threads. Maximizes productivity by eliminating tool changing. Particularly suitable
for machining non-ferrous metal.
BGF-3:
Solid Carbide Drill Thread Mill with 3 Flutes (Cast Iron)
Optimized version of the BGF tool, particularly suitable for machining materials that yield short chips. Because of the greater number of cutting edges, this tool offers enhanced performance with improved centering. Particularly suitable for machining cast iron.
BGFS:
Solid Carbide Circular Drill Thread Mill (Steels up to 63Rc)
Tool for the combined production of bore and thread in one operation. Universally
applicable in steels, hardened materials and non-ferrous metals.
Specialty Combination Thread Milling Cutters
Combination thread milling cutters offer a comprehensive solution by integrating spotfacing, counterboring, drilling, and thread milling into a single operation. This integrated approach significantly reduces production time by eliminating the need for tool and machine changes.
JBO thread milling combination tools are made to order and optional features such as integrated RFID-Chip, internal coolant supply, and indexable facing and/or chamfering inserts are available. These high-tech tools are designed to enhance efficiency and versatility. Interchangeable thread mill cutter sizes and facing/chamfering bits can be easily swapped in the tool shank, providing flexibility for different machining requirements.
Shell Type thread Milling Cutters
Specialty shell-type thread milling cutters designed to quickly and efficiently produce external threads
Advantages:
- Reduction of cutting time
- Exceptional tool life
- Excellent thread quality
- Right-Hand and Left Hand threads can be produced with the same inserts
- By changing the inserts, different pitches and profiles can be produced with the same tool
- Adjustable exact thread depth
- Optimized for high coolant flow
- Optional removal of the incomplete first thread
- Shorter machining time due to higher feed rates
- Increased tool life due to larger number of cutting edges
- Higher grade thread surface texture due to rugged construction
- Suitable for nearly any thread or profile
- Particularly advantageous for long run production of steel components
- Distinctly lower tooling costs per workpiece
- Inserts can be reground several times
Excellent for machining of non-ferrous metals- Cost-effective solution by geometrically simple milling inserts
- Optimum accessibility for the replacement of milling inserts
- Suitable for nearly any thread or profile
- Particularly suitable for processing easy to machine materials in
serial production - Significantly lower cost per piece than solid carbide milling tools
- Inserts can be reground several times
