This is a revolutionary new concept of engraving tools with indexable carbide inserts.
They offer you the ability to produce HIGH QUALITY ENGRAVING in most materials.
The latest coated carbide grades help you to obtain higher speed and feed rate, dramatically reducing your cycle time.

Main Features
• High Positive Rake Angle
Indexable insert.
Suitable for engraving all types of materials, such as plastic, non-ferrous metal, aluminum, carbon steel and stainless steel.

• Multi-Side Grinding
Full peripherally ground insert to ensure effi cient repeatability. It performs excellently without producing any burrs, especially in aluminum and stainless steel.

• High Speed, High Feed Rate
Designed to run at high speed, up to 20000 r.p.m.
Feed rate 0.08mm (0.003”) / rev. apply to aluminum;
0.05mm (0.002”) / rev. apply to stainless steel.
Reduces engraving cycle time!

• Economical
Each indexable insert has 2 cutting edges.
No resharpening required. Tool length is unchanged.
No need to reset after changing insert or cutting edge.
Excellent repeatability!

• Applications
Universal for marking number and almost any character.
