Cleveland C27166 Chucking Reamer

The Cleveland C27166 is a straight-flute chucking reamer made from high-speed steel with a bright uncoated finish. It is sized at 1.25 inches and has an overall length of 11 inches. This fractional-inch tool is intended for machinists and maintenance technicians who need to enlarge and finish existing holes to precise diameters in a variety of ferrous and non-ferrous materials.

Thermals Noise Power

As a non-powered cutting accessory, the reamer generates no electrical noise, draws no power and produces no self-generated heat during operation. Cutting temperatures depend entirely on the host machine speed, feed rate, workpiece material and the coolant or lubricant applied by the operator. Proper cutting-fluid selection keeps the tool and workpiece within safe thermal limits.

Bundled Accessories Software

The reamer is supplied as a single cutting tool with no additional accessories, coatings or software included. The bright uncoated surface is ready for immediate use or for the application of a user-preferred coating. No digital assets, drivers or calibration certificates accompany the product.

Questions about this item

How is the Cleveland C27166 chucking reamer installed in a machine spindle, and what step is often missed?

Insert the straight shank into a matching collet or chuck, tighten securely, and verify the reamer runs true before cutting. The step often missed is checking concentricity with a dial indicator after clamping.

What maintenance or replacement will the Cleveland C27166 high-speed steel reamer need over time?

The bright uncoated flutes will dull with use. Resharpen the cutting edges on a tool-and-cutter grinder when hole finish degrades, or replace the reamer once the 1.25 in diameter falls below tolerance.

What limit appears first when the Cleveland C27166 reamer is used continuously in tough material?

Heat buildup in the high-speed steel body reduces hardness and causes rapid flank wear, so cutting speed must be lowered or coolant applied to prevent premature dulling of the 1.25 in cutting diameter.
