Cleveland C25212 Chucking Reamer 0.124 in Hss Straight Flute

Product Description

The CLEVELAND C25212 is a straight-flute chucking reamer machined from high-speed steel and designed to finish-ream drilled holes to a precise 0.124-inch diameter. With an overall length of 3.5 inches and a flute length of 0.875 inches, this reamer fits standard drill press and CNC machine chucks for controlled material removal in finishing operations. The bright, uncoated finish suits general-purpose ferrous and non-ferrous machining. Six flutes provide balanced cutting action and consistent surface finish in production and job-shop environments. Machinists, tool-and-die makers, and maintenance technicians working with close-tolerance bores rely on this style of reamer for final hole sizing after drilling.

This reamer is suited for light finishing cuts in through-holes and blind-hole applications where a precise 0.124-inch finished diameter is required. The straight shank accepts standard drill chucks and collet holders on vertical mills, drill presses, and CNC machining centers. Its compact flute length makes it practical for shallow-bore work in plate, block, and component machining across metalworking, maintenance repair, and light manufacturing operations. The right-hand cut direction is standard for conventional clockwise spindle rotation.

Key Features

• 0.124-inch finished bore diameter with right-hand cut for standard spindle rotation
• Six straight flutes deliver balanced cutting action and consistent hole finish
• High-speed steel construction provides durability across a range of workpiece materials
• Bright uncoated finish — suitable for use with cutting fluids on ferrous and non-ferrous materials
• Straight shank fits standard drill chucks and collet holders without special toolholding
• Compact 0.875-inch flute length optimized for shallow-bore finishing applications

Compatibility

Designed as a standard chucking reamer for use in drill press chucks, collet holders, and CNC machining center toolholding systems requiring a 0.124-inch finished hole diameter.

Installation Notes

A licensed machinist or qualified technician should verify spindle speed and feed rate are appropriate for the workpiece material before use. Always ensure the machine spindle is fully stopped and the workpiece is securely clamped before tool changes. Use cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Inspect the reamer cutting edges for wear or chipping before each use.
