Value Collection SM0406020 Chucking Reamer 0.6020 in Hss

Product Description

The VALUE COLLECTION SM0406020 is a 6-flute high-speed steel (HSS) chucking reamer designed to finish-size drilled holes to a precise 0.6020-inch diameter. With an overall length of 8 inches and a 2-inch straight flute section, this reamer delivers accurate, consistent bore sizing in metalworking and machining operations. The straight-cylindrical shank seats securely in drill chucks, collets, and floating holders. The bright, uncoated HSS construction suits general-purpose reaming in a wide range of ferrous and non-ferrous materials. Right-hand cutting direction is standard for conventional machine spindle rotation. Machinists and tool-and-die professionals reach for this style of reamer when a drilled hole requires close-tolerance finishing.

This chucking reamer is suited for use in manual mills, CNC machining centers, drill presses, and lathes wherever a precise 0.6020-inch finished bore is required. The straight-flute geometry performs reliably in through-holes and blind holes with adequate chip clearance. Typical applications include fixture-hole finishing, bearing seat preparation, and dowel-pin hole sizing in job-shop and production machining environments. The straight-cylindrical shank makes it compatible with a broad range of standard toolholding systems without special adapters.

Key Features

• 0.6020-inch finished bore diameter for close-tolerance hole sizing
• 6 straight flutes for smooth cutting action and even chip evacuation
• HSS construction provides toughness across a wide range of workpiece materials
• Bright, uncoated finish — ready to use as-delivered or re-sharpenable
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction matches conventional machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck, ER collet, or floating reamer holder accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists following standard shop practices. Secure the straight-cylindrical shank firmly in the toolholder before use and verify runout with an indicator if close tolerances are critical. Always reduce spindle speed and increase feed rate relative to drilling — reaming typically requires slower RPM and a positive feed to prevent chatter and bell-mouthing. Ensure the workpiece is rigidly fixtured and apply appropriate cutting fluid for the material being reamed.
