Fixes: reduce tool overhang to bar diameter plus 1-2 mm, adjust spindle speed for the workpiece size, increase feed rate to break the chip, add a small chamfer to the leading edge, or switch to a stiffer self-grip blade for deep cuts beyond 8 mm.\"}},\n{\"@type\":\"Question\",\"name\":\"Can I use a parting insert for grooving and vice versa?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes - MGMN inserts are explicitly dual-purpose. The geometry handles both parting (axial straight-in) and grooving (radial in-feed). What matters is matching the width to the operation: a 2 mm-wide groove needs a 2 mm insert.\"}},\n{\"@type\":\"Question\",\"name\":\"What carbide grade should I pick for stainless vs mild steel vs cast iron?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"PC9030 PVD TiAlN is the all-rounder for carbon and alloy steel. For stainless, Inconel or titanium use a tougher PVD grade like GC1125 or IC908. For cast iron use an uncoated K-grade or CVD-coated NC3030. We can match the grade to your part drawing.\"}},\n{\"@type\":\"Question\",\"name\":\"How deep can I cut with a standard MGEHR holder before I need a deep-cut blade?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"For an MGEHR2020 holder, cut depth up to about 22 mm is safe. For 22-35 mm switch to an Iscar Self-Grip GHDR-style deep-parting blade. Past 35 mm, use specialty GTN-4\/-5\/-6 reinforced blades.\"}},\n{\"@type\":\"Question\",\"name\":\"Do I need different inserts for face grooving vs OD grooving?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"You can run a standard MGMN insert on the face if the groove diameter is large. But for small-radius circular grooves use a dedicated face-grooving holder (MGFHR series) with a curved blade that follows the groove arc. The insert itself is still a standard MGMN; only the holder geometry changes.\"}},\n{\"@type\":\"Question\",\"name\":\"What is the difference between MGMN and GTN inserts?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"MGMN is an open-standard insert geometry made by many manufacturers - cheap and universally available. GTN is Iscar's self-clamping system - faster insert changes (no Torx key) and rated for deeper, more rigid cuts, but Iscar-only. For most workshops MGMN is the practical default.\"}},\n{\"@type\":\"Question\",\"name\":\"Why do parting inserts have two cutting corners?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Most MGMN inserts are double-ended - one cutting edge at each end. When the first dulls you flip the insert and use the fresh end. Effectively two inserts for the price of one. Single-ended Sandvik N123 \/ CoroCut 1-2 inserts trade the second edge for a more aggressive chip-breaker geometry.\"}},\n{\"@type\":\"Question\",\"name\":\"Can I part stainless steel without coolant?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Technically yes, but you will burn the insert in 30 seconds. Stainless work-hardens at the cutting edge and chips carry the heat. Run flood coolant or high-pressure air-blast aimed at the chip exit. PC9030 or GC1125 grades tolerate intermittent dry cuts; cheap K-grade inserts will not.\"}},\n{\"@type\":\"Question\",\"name\":\"Do you stock genuine Korloy, Iscar and Sandvik or compatible aftermarket?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"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.
