Bedra EDM Wires

Cobra Cut

COBRA CUT® Type A

This hard, zinc-coated wire electrode is especially suitable for machines with automatic traders. Due to excellent straightness and precision, it guarantees very good surface qualities and allows precision cuts and fine detail with the highest reliability in automatic operations.

COBRA CUT® B

The special CuMg core of this electrode provides high electrical conductivity. Its rougher, oxidized surface benefits flushing conditions and is advantageous for the cutting of tall workpieces (>100mm). Recommended for fast cutting of graphite and aluminium alloys. This wire is suitable for tapering to 20o but has limited capability for skim cutting and automatic wire threading.

Asset 8

COBRA CUT® Type D

This wire electrode has been developed for EDM machines with high-power generators. It has a high thermal and electrical conductivity due to its special coating, making it suitable for speed cutting as well as contour precision cutting. This wire electrode may also be used on machines with automatic threading.

Asset 6

COBRA CUT® Type G

The modified surface of this wire electrode represents the difference to the COBRA cut, Type A. It is therefore recommended for conical cuts (tapering) on AGIE EDMs with toroid guides.

Asset 7

Bronco Cut

BRONCO CUT® Type X

This high-performance, multipurpose EDM wire with a specific zinc-rich coating, is suitable for precision cutting as well as high-speed cutting. Excellent automatic threading reliability is another

MEGACUT® TYPE A

This zinc-coated precision wire is used when fine surfaces are required. This wire is also recommended when cutting carbides and poly-crystalline diamond

Asset 4

MEGACUT® TYPE D

Due to its special coating, this electrode is ideal for speed cutting, providing the highest performance. This wire is also recommended for tall workpieces, interrupted cuts and poor flushing conditions.

Asset 3

MicroCut

MicroCut

This EDM wire. especially developed for fine and micro EDMing is available in diameters down to 0.0 2mm. With a special zinc-rich brass coating over its high-strength steel core, it provides optimum process stability, the highest dimensional accuracy and superior surface finishes.
