Product Description
CMT ER40 Precision Collet - 10mm Bore Diameter is a high-accuracy tool-holding collet engineered for CNC routers, machining centers, and point-to-point machines that require reliable, repeatable clamping of 10mm shank tooling. Precision ground to DIN 6499 standards, this collet delivers minimal runout and consistent tool positioning, making it a dependable choice for demanding woodworking and CNC machining operations where dimensional accuracy directly affects cut quality.
Key Features
- ER40 Collet System - compatible with the widely used ER40 standard, allowing straightforward integration into existing ER40 tool holders and spindle configurations on CNC equipment.
- 10mm Bore Diameter - precisely sized to accept 10mm shank router bits and CNC tools, ensuring a secure, concentric fit that reduces tool vibration and chatter during cutting passes.
- Precision Ground to DIN 6499 Standard - manufactured to tight dimensional tolerances, this collet delivers minimal runout and maximum tool accuracy, resulting in cleaner cuts, better surface finishes, and extended tool life.
- Clamping Tolerance of 0.015mm - exceptionally fine holding tolerance keeps tooling centered and stable, which is critical for high-precision routing, drilling, and profiling applications.
- Replaceable Design - functions as a direct replacement collet within ER40 systems, making it practical to restore spindle performance without replacing the entire tool holder assembly.
Why This Product
- Shops running 10mm shank tooling in ER40 spindles get a precisely matched collet that eliminates guesswork about fit and holding security, keeping production accurate and consistent.
- The DIN 6499 precision ground construction means runout is held to a minimum, which directly translates to tighter part tolerances and reduced scrap when working with CNC routers or machining centers.
- A 0.015mm clamping tolerance provides the kind of grip consistency that matters in repetitive production runs, where even small variations in tool position can affect finished part dimensions.
- As a replaceable collet, it extends the working life of an existing ER40 tool holder setup - a straightforward, cost-effective way to maintain spindle accuracy without investing in new tooling hardware.
