More versatile long-grooving

We have grown our parting-off and grooving assortment with several significant additions.  

This includes a complete offer for a variety of machining conditions and materials comprising a new insert, two new geometries, a grade, blades and tool holder.   

The new 25mm GL double-edged insert is available in a variety of widths from 2 – 6mm. Targeting long-grooving applications, GL supports 60 per cent deeper capacity, over our existing LCMF16 insert. 

A PVD grade, G8330, has been introduced for the GL insert to provide a versatile and stable option when machining steel, stainless steel and cast iron.  

The insert is also supported by two new geometries. PR is the first choice for medium to high feeds in a variety of machining conditions. Its cutting-edge strength resists cracking when grooving interrupted cuts and is ideal for the parting-off of bars.

The PM geometry is an option for low to medium feeds on soft materials, such as austenitic stainless steel, as it offers greater resistance to built-up edge and reduces the bur left when parting-off tubes.

A new range of external tool holders are available with shank dimensions from 16 – 25mm. Their advanced design supports stable cutting and resists vibration, promoting high-quality surface finish. The holders provide an overhang up to 32mm. 

Designed for small part machining, the tools feature a 30-degree angled screw position for easier indexing and a brace to increase toughness.  

In addition, a line of universal tool blades, offering heights between 26 – 32mm, are now available. It features a double-sided clamping key and a new design which enables inserts to be replaced with one hand.
