With a reamer diameter of 0.0635 inches (Wire Size 52) and a diameter tolerance of 0.0000 to +0.0003 inches, this tool delivers consistent, tight-tolerance bore sizing. The 4-flute, left-hand spiral geometry with right-hand cutting direction provides smooth chip evacuation and stable cutting action. An overall length of 1.9685 inches and a straight shank make it compatible with standard chucks and collets used on drill presses, lathes, and CNC machining centers. The bright polished finish reduces friction and extends tool life in production environments.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for finishing small-diameter holes in ferrous and non-ferrous metals where dimensional accuracy is critical. With a flute length of 0.7087 inches, it is optimized for shallow through-holes and blind holes common in precision component manufacturing, tooling, and fixture work. It is typically installed and operated by machinists and CNC operators in job shops, production facilities, and toolrooms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003e4-flute left-hand spiral geometry promotes smooth chip flow and chatter reduction\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of 0.0000 to +0.0003 inches for precise bore sizing\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and aids chip release\u003c\/li\u003e\n\u003cli\u003eStraight shank fits standard chucks and collets without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision chucking reamer for use in standard drill chucks, ER collets, and straight-shank toolholders on CNC machining centers, lathes, and drill presses requiring a 0.0635-inch finished bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers should be installed by qualified machinists following shop safety procedures. Power down and lock out the spindle before mounting or removing the tool. Ensure the shank is fully seated and the chuck or collet is properly torqued before operation.
