Cleveland C25060 Chucking Reamer 1/16 in Hss Straight Flute

Product Description

The CLEVELAND C25060 is a straight-flute chucking reamer designed for finishing drilled holes to close dimensional tolerances. Built from high-speed steel with a bright, uncoated finish, it delivers consistent performance in a wide range of metals and engineering materials. The reamer measures 0.0625 inches (1/16 inch) in diameter with a 2.5-inch overall length and a 0.5-inch flute length. With 4 flutes and a right-hand cut, it produces smooth, accurate bores when used in drill presses, lathes, or CNC machining centers. The straight shank mounts directly into standard chucks or collets without adapters.

This reamer is suited to precision hole-finishing operations in job shops, maintenance facilities, and production environments. The 1/16-inch diameter targets small-bore applications such as pin holes, bushing bores, and dowel hole alignment work. It is well matched for use in ferrous and non-ferrous stock where a controlled, finished diameter is required after drilling. Machinists and toolmakers working in light manufacturing or repair operations will find it appropriate for hand-fed and machine-fed cycles alike.

Key Features

• High-speed steel construction for durability across a broad range of workpiece materials
• Bright, uncoated finish suitable for use with cutting fluid or dry in softer materials
• 4-flute straight geometry for consistent chip evacuation in through-hole and blind-hole reaming
• Right-hand cut for standard spindle rotation on lathes, drill presses, and machining centers
• Straight shank for direct chuck or collet mounting without additional toolholders
• 0.0625-inch diameter targets small-bore precision finishing where drill drift tolerance is insufficient

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems accepting straight-shank tooling at the stated 0.0625-inch diameter.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians using standard lathe tailstocks, drill press chucks, or CNC tool holders. Ensure the workpiece is securely fixtured and the spindle is stopped before mounting or removing the tool. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve bore finish. Never run a reamer in reverse, as this dulls the cutting edges and degrades dimensional accuracy.
