With a collet size of 0.187 inches and a minimum collet capacity of 0.148 inches, this collet accommodates a range of round shank cutting tools within that clamping range. The overall length is 1.24 inches and the overall diameter is 0.827 inches. PARLEC collets are manufactured to close tolerances, making them a standard choice for machinists and tool crib technicians who require consistent, repeatable tool runout in production environments.\u003c\/p\u003e\n\u003cp\u003eThis collet is suited for use in job shops, production machining facilities, and maintenance operations where ER20 toolholding is the specified standard. It is commonly installed in ER20 collet chucks on vertical machining centers, CNC mills, and multi-axis machining platforms. End mills, drills, reamers, and other round shank tools with shanks up to 0.187 inches are the typical applications. Installation is performed by qualified machinists or toolroom technicians as part of standard tool change and presetting procedures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eER20 collet series for compatibility with standard ER20 collet chucks\u003c\/li\u003e\n  \u003cli\u003eCollet size of 0.187 inches with a minimum clamping capacity of 0.148 inches\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.24 inches and overall diameter of 0.827 inches\u003c\/li\u003e\n  \u003cli\u003eCompact, precise form factor suited for close-tolerance CNC toolholding\u003c\/li\u003e\n  \u003cli\u003eSold individually  -  minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER20 collet chucks and toolholding systems that accept the ER20 collet series.
