Dormer Pramet GL grooving tool

Dormer Pramet has added a new set of tooling to its parting-off and grooving assortment. The 0.98" GL double-edged insert is available in a variety of widths ranging from 0.08" 0.236". Designed for long-grooving applications, GL supports 60% capacity over the existing LCMF16 insert, the company says. The G8330 PVD insert grade is said to maintain stability when machining steel, stainless steel and cast iron. 

The insert is also supported by two new geometries. The PR geometry is designed 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 barstock, according to the company. The PM geometry is an option for low to medium feeds into softer materials, such as austenitic stainless steel, as it offers greater resistance to built-up edge and reduces burrs when parting-off tubes. 

Toolholders are available with shank dimensions ranging from 0.63" to 0.98" and an overhang ranging to 1.26". 

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


  • Choose The Best Drill Point Geometry

    The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.

  • Tool Considerations for High Speed Cutting

    Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?

  • Start With The Right Speeds And Feeds

    Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
