M.a. Ford. 27202650 Chucking Reamer 0.0265 in Solid Carbide

Product Description

The M.A. FORD. 27202650 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production drilling applications. With a reamer diameter of 0.0265 inches and a tight tolerance of +0.0001 to +0.0003 inches, this tool holds close tolerances required for small-diameter bore finishing. It features four straight flutes, a right-hand cutting direction, and a straight-cylindrical shank for use in standard chucks and collets. The bright, uncoated carbide construction provides rigidity and wear resistance in ferrous and non-ferrous materials. Machinists and toolroom technicians are the primary users of this reamer in CNC and manual machine environments.

This reamer is suited for small-diameter finish reaming operations where dimensional accuracy is critical. The 0.0265-inch diameter places it in the micro-bore range, making it appropriate for instrument components, medical device parts, electronics hardware, and other precision-machined workpieces requiring consistent hole size and surface finish. The 1/4-inch flute length and 1-1/2-inch overall length make it compact and well-suited for shallow-hole applications in production or prototype settings.

Key Features

• Solid carbide construction for rigidity and extended tool life in small-diameter applications
• Reamer diameter of 0.0265 inches with tolerance of +0.0001 to +0.0003 inches for precision bore finishing
• Four straight flutes with right-hand cutting direction for consistent chip evacuation
• Bright, uncoated finish suitable for use across a range of workpiece materials
• Straight-cylindrical shank compatible with standard chucks and collets
• Compact overall length of 1-1/2 inches for use in confined or shallow-hole setups

Compatibility

Designed as a Series 272 chucking reamer for use in CNC machining centers, drill presses, and manual lathes equipped with standard straight-bore chucks or collets accepting a straight-cylindrical shank at this diameter range.

Installation Notes

This reamer is installed and operated by machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in a matched collet or chuck before operation to prevent runout that can damage the tool or compromise hole tolerance. Use appropriate cutting fluid or coolant recommended for the workpiece material, even though the tool does not support through-coolant. Inspect the reamer for chipping or wear before each use, as solid carbide micro-diameter tools are brittle and sensitive to lateral loading.
