Precision HSS RoundShank Reamer — Six Straight Flutes for Clean, Accurate Finishes Key benefits Produces clean, accurate bores: Designed to ream aluminum, cast iron, copper, magnesium alloys, plastics, wood and more for reliable, repeatable surface finishes. Faster, more consistent cutting: Six straight flutes improve chip evacuation and cutting efficiency so you spend less time deburring and more time assembling or continuing operations. Durable under load: Manufactured from speed steel (HSS) to deliver long life and maintain cutting geometry in demanding machining tasks. Flexible machine compatibility: Round shank design is compatible with drilling machines and milling machines and fits standard collets for versatile use. What makes it stand out Straightflute geometry specifically tuned for effective chip removal across a wide range of materials, reducing clogging and tool chatter. HSS construction balances toughness and edge retention for repeated reaming without premature wear. Round shank / colletready form factor simplifies mounting and changeover between drills and mills. Practical performance details Function: Reaming for sizeaccurate holes and improved surface finish after drilling or boring. Compatibility: Works with standard drilling machines and milling machines; designed to be used with collet chucks or compatible roundshank holders. Materials: Effective on nonferrous and light ferrous metals (aluminum, cast iron, copper, magnesium alloys), as well as plastics and wood. Typical use scenarios Finishing bolt holes in machined aluminum brackets to precise tolerance before assembly. Reaming bearing seats in a lightduty milling setup to achieve concentric, smooth bores. Cleaning and sizing holes in composite or plastic fixtures after initial drilling to ensure a snug fit for inserts or fasteners. Suggested handling notes Use appropriate feed and speed for the workpiece material and machine rigidity. Keep the flutes clear of chips; periodic chip clearing will extend tool life and maintain finish quality. Secure in a suitable collet or roundshank holder to minimize runout and ensure results.
