Built to a 0.0360-inch (No. 64 wire gauge) diameter with a tight tolerance of 0.0000 to +0.0003 mm, this reamer delivers consistent bore sizing in hardened and difficult-to-machine materials. The 4-flute spiral design with left-hand spiral direction and right-hand cutting action promotes smooth chip evacuation and reduces chatter during the cut. The bright, uncoated finish suits a broad range of materials without added coating cost. Machinists and tool-and-die professionals install this reamer in CNC machining centers, drill presses, and manual lathes wherever repeatable, close-tolerance bore finishing is required.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for small-diameter precision reaming operations in production and job-shop environments. With a 50.00 mm (1.9685 inches) overall length and a 7.00 mm flute length, the MR34-0358.281 is optimized for shallow, tight-tolerance holes in the sub-1.00 mm diameter range. The straight-cylindrical shank seats cleanly in standard collet chucks and drill chucks. Typical applications include reaming holes in instrument components, small mechanical assemblies, watch-gear fixtures, and precision medical or aerospace parts where bore finish and diameter accuracy are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003eNo. 64 wire gauge diameter (0.0360 inches) with tolerance of 0.0000 to +0.0003 mm for precise bore sizing\u003c\/li\u003e\n  \u003cli\u003e4-flute left-hand spiral, right-hand cutting geometry promotes efficient chip flow and smooth finish\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating degradation risk in sensitive or reactive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for direct seating in collet chucks and standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eCompact 50.00 mm overall length suits confined setups and short-reach spindle configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard straight-shank collet chucks and drill chucks accepting small-diameter straight-cylindrical shanks in CNC and manual machining equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis reamer is installed by machinists in machine tool spindles equipped with a compatible collet or drill chuck. Ensure the machine spindle and workpiece are properly secured before engaging the reamer.
