Cleveland C26217 Chucking Reamer 9/16 in Hss Straight Flute

Product Description

The CLEVELAND C26217 is a straight-flute chucking reamer designed to finish-ream drilled holes to precise tolerances in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in general machining applications. The reamer measures 9/16 inch (0.5625 inch) in diameter with an overall length of 8 inches and a flute length of 2 inches. Eight flutes and a right-hand cut provide smooth stock removal and accurate hole sizing. The straight shank is compatible with standard drill chucks and collet holders commonly found on lathes, drill presses, and milling machines.

This chucking reamer is suited for machine shop and production environments where holes require a fine finish and close dimensional accuracy after drilling. It is appropriate for use in ferrous and non-ferrous metals where HSS cutting performance is acceptable. Licensed machinists and toolroom operators are the typical end users. It is not rated as an over- or under-size reamer and is not configured as a dowel pin reamer, making it a standard sizing tool for everyday shop use.

Key Features

• 9/16 inch (0.5625 inch) reamer diameter for precise hole finishing
• High-speed steel construction for durability in general-purpose machining
• 8 straight flutes for smooth cutting action and consistent surface finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight shank fits standard drill chucks and collet-style toolholders
• Bright, uncoated finish — no coating buildup that could affect dimensional accuracy

Compatibility

Designed as a standard-tolerance chucking reamer for use in lathes, drill presses, and milling machines equipped with a drill chuck or straight-shank collet holder accepting a 9/16 inch shank.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom practices. Power down and de-energize the machine spindle completely before mounting or removing the reamer from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Never exceed the machine spindle speed recommended for the workpiece material and tool diameter.
