This is the CNCHome-Beyond top-248 best-selling catalog — the most-ordered indexable inserts and CNC cutting tools across all 8 brands we carry, refreshed quarterly based on actual order volume. Every product in this collection is ISO 1832 standard sized (interchangeable across brands), 30–50% below OEM list price through direct-from-factory supply, and shipped from our Hangzhou warehouse in 3–7 days to 50+ countries. Browse the listings below to see the most popular turning, milling, grooving, threading, and drilling inserts, or use the brand pages and sub-collections to drill down to a specific geometry or grade.
What's in the Best Sellers List?
- High-volume turning inserts (CNMG / TNMG / WNMG / DNMG / VNMG) — the negative-geometry workhorse for steel and stainless steel roughing & finishing. These are the most-ordered SKUs across all brands, and consistently the first inserts to sell out.
- Positive turning inserts (CCMT / TCMT / DCMT / VBMT) — for small parts, finishing, and Swiss-type lathe work. Most popular on shop floors running high-mix production.
- Milling inserts (APMT / RPMT / LNMU / WNMU / SEKT) — face, shoulder, profile, and high-feed milling across steel, stainless, cast iron, and aluminum.
- Grooving & parting inserts (MGMN / MRMN / FMM / GMM) — external grooving, parting off, face grooving, recessing.
- Threading inserts (16ER / 27VER / 06IR / 08IR) — external and internal metric, UN, BSPT, NPT threading.
- Drilling inserts (SPMG / SOMX) — U-drill and modular drill inserts for high-velocity bolt-circle drilling.

How We Pick "Best Sellers"
The 248 products in this collection are the highest-velocity SKUs across all of CNCHome-Beyond — chosen by actual B2B order volume over the trailing 90 days, refreshed quarterly. We don't pay for placement, and we don't boost our house brands artificially. If a Sandvik GC4325 CNMG 120408 sells more than a KORLOY NC3030, both appear in proportion. This list is the closest thing to an unbiased "what's working in real machine shops right now" snapshot.

Frequently Asked Questions
Q: How often is the "Best Sellers" list refreshed?
A: Quarterly, based on actual order volume from the trailing 90 days. The list automatically favors high-velocity SKUs that are restocked frequently, so it stays current with real shop-floor demand rather than editorial picks.
Q: Are best-selling inserts always the cheapest?
A: Not necessarily. "Best sellers" measures order volume, not price. A premium Sandvik GC4325 at $14 may sell more units than a budget KORLOY NC3030 at $9 because shops trust the Sandvik grade for critical jobs. Use the Best Sellers list to see what the market is buying, then compare prices across the 8 brands in the catalog.
Q: I have a specific insert code I need to replace — can you cross-reference it?
A: Yes. Email chao@cnchome-beyond.com the SKU (e.g. CNMG 120408-PM GC4325) and our engineers send back a matched KORLOY / Mitsubishi / Tungaloy / OYYU equivalent within one business day, including grade cross-reference and recommended cutting parameters. The cross-reference is free whether or not you order.
Q: What's the typical lead time on best-selling items?
A: Most best-selling items are stocked in our Hangzhou warehouse and ship within 24-48 hours via DHL / UPS / FedEx, arriving in 3-7 business days to 50+ countries. DDP (delivered duty paid) is available for the US, EU, and most of Asia. For volume orders above 1,000 units, expect 2-3 week lead time as we may need to pull from the brand's regional warehouse.
