Parting and grooving tools, end-to-end
Cut-off bars, slot grooves, retain rings, separate finished parts — all on the same machine setup. Our parting and grooving lineup covers parting (cut-off), external grooving, internal grooving and face grooving. Square-shank holders, round boring bars, deep-cut self-grip blades, and a complete carbide insert grade matrix.
Coverage is built around the industry-standard MGMN insert family (1.5 mm to 6 mm), the matching MGEHR / MGEHL external holders and MGIVR / MGIVL internal boring bars, plus Iscar self-grip GTN blades for deep cut-off and Sandvik N123 / CoroCut inserts for stainless and superalloys.

Parting & grooving — common questions
What is the difference between parting and grooving?
Parting (cut-off) separates a workpiece into two by feeding straight in until the bar is cut through. Grooving makes a slot or recess without cutting through. Both use similar MGMN inserts and holders.
Which insert width should I start with for general work?
2 mm (MGMN200) is the safest default. It handles most parting jobs on 12–30 mm bar and cuts standard O-ring grooves. Step down to 1.5 mm for minimum kerf on small bar; step up to 3 mm for bars over 25 mm.
What does the “MGEHR2020-3” code mean?
M = mono-block grooving holder; G = grooving/parting; E = external; H = horizontal feed; R = right-hand; 20×20 = shank cross-section in mm; -3 = insert seat width in mm. So MGEHR2020-3 is an external right-hand holder with a 20×20 mm square shank for 3 mm MGMN inserts.
Why does my parting tool keep chattering?
Reduce overhang to bar diameter plus 1–2 mm, adjust spindle speed, increase feed to break the chip, add a small chamfer to the insert leading edge, or switch to a stiffer self-grip blade past 8 mm depth.
Can I use a parting insert for grooving and vice versa?
Yes — MGMN inserts are explicitly dual-purpose. The geometry handles both parting (straight-in) and grooving (radial in-feed to defined depth). Match the width to the operation.
What grade should I pick for stainless vs mild steel vs cast iron?
PC9030 PVD TiAlN for carbon and alloy steel. Sandvik GC1125 or Iscar IC908 for stainless, Inconel, or titanium. CVD NC3030 or uncoated K-grade for cast iron.
How deep can I cut with a standard MGEHR holder?
Up to ~22 mm safely. For 22–35 mm switch to an Iscar Self-Grip GHDR blade. Past 35 mm use GTN-4/-5/-6 reinforced blades.
Do I need different inserts for face grooving vs OD grooving?
For small-radius circular grooves use a dedicated MGFHR face-grooving holder with a curved blade. The insert itself is still a standard MGMN; only the holder geometry changes.
What's the difference between MGMN and GTN inserts?
MGMN is an open standard — universally available and cheap. GTN is Iscar’s self-clamping system — faster insert changes, rated for deeper rigid cuts, but Iscar-only. MGMN is the practical default; GTN for production cells.
Can I part stainless steel without coolant?
Technically yes, but the insert will burn within 30 seconds. Run flood coolant or high-pressure air-blast at the chip exit. PC9030 or GC1125 tolerate intermittent dry cuts; cheap K-grade inserts will not.
Do you stock genuine Korloy, Iscar and Sandvik or compatible aftermarket?
Genuine. We are authorised distributors for Korloy and Pafana in the UAE, and stock Iscar and Sandvik Coromant lines. Every insert ships in original branded packaging with the lot code.
