Cleveland Golf 25807 Chucking Reamer 3/8 inch 6 Flute HSS

Precision Hole Finishing Tool

The Cleveland Golf 25807 chucking reamer is a 3/8 inch, six-flute cutting tool made from high-speed steel. It is designed for machinists and maintenance technicians who need to enlarge and finish existing holes to precise tolerances. The straight-flute geometry suits through-hole and blind-hole applications in a variety of ferrous and non-ferrous materials. This uncoated tool delivers reliable performance for general-purpose workshop use.

Thermal And Power Behaviour In Use

As a non-powered hand tool, the reamer generates no operational noise or electrical power draw. Heat is produced only through friction at the cutting interface during manual or machine-driven rotation. Proper cutting fluid application manages this thermal load effectively, preserving the high-speed steel edge and workpiece integrity. There are no thermals, acoustics or power metrics to consider beyond standard machining practice.

Upgrade Path And Limitations

This reamer replaces worn or undersized finishing tools when hole accuracy or surface finish degrades beyond acceptable limits. The jump is worth it when a standard drill leaves a rough or oversized bore that requires tight dimensional control. It is not suited for heavy stock removal, roughing operations, or creating holes from solid material where a drill or boring bar is required first.
