Case Study: Real Business, Real Results
St. Louis, Missouri – A local metal fabrication shop sought to improve tool retention and cutting accuracy.
“Switching to the TNMC 43NG187 inserts gave us noticeably steadier cuts and reduced tool slippage, making our day-to-day jobs smoother and more precise.”
Rick Harmon – Shop Manager
Improved machining consistency by 30% and reduced replacement costs.
How the Neutral Rake and Through-Hole Design Keep Your Setup Stable
The TNMC 43NG187’s neutral rake angle works like having a level-headed partner in your machining process—meaning it doesn’t push or pull aggressively during cutting, allowing for smoother, controllable cuts. Plus, the thru hole that’s countersunk on both sides ensures the insert sits tight and firm in its holder, much like a seatbelt keeping you secure on a bumpy ride. This helps prevent shifting during operation, reducing chatter and enhancing your finish quality. Think of it as both precision and peace of mind rolled into one small but mighty piece.
