Hertel 45675220 Chucking Reamer 0.203 in Solid Carbide

Product Description

The HERTEL 45675220 is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a 0.203-inch diameter and a 4-flute straight flute configuration, this reamer delivers accurate, repeatable bore sizing in a wide range of materials. The bright, uncoated solid carbide construction provides rigidity and wear resistance suitable for close-tolerance work. The straight cylindrical shank allows direct mounting in standard chucks or collets on drill presses, lathes, and CNC machining centers. Overall length is 3 inches with a 1-inch flute length, keeping the tool compact for short-reach applications.

This chucking reamer is suited for production and maintenance machining environments where hole diameter accuracy is critical. Its right-hand cutting direction and straight flute geometry make it a practical choice for reaming through-holes and blind holes in metals and other machinable materials. Machinists, tool-and-die makers, and maintenance technicians working in job shops or production facilities will find this reamer appropriate for finishing drilled or bored holes to tight dimensional tolerances.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding materials
• 0.203-inch diameter falls within the 0.2000 to 0.2499 inch reamer diameter range
• 4-flute straight flute geometry for consistent chip evacuation and smooth bore finish
• Bright, uncoated finish maintains as-ground edge geometry without coating buildup
• Straight cylindrical shank for direct mounting in standard chucks and collets
• Right-hand cutting direction, compatible with conventional spindle rotation

Compatibility

Designed as an OEM-style solid carbide chucking reamer suitable for use in standard drill press chucks, lathe tailstock chucks, and CNC collet holders that accept a straight cylindrical shank in the 0.203-inch diameter class.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations. Secure the straight shank firmly in the chuck or collet before operation and verify runout with an indicator before cutting. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid for the workpiece material to achieve optimum surface finish and tool life. Never use a worn or out-of-round chuck, as excess runout will compromise bore tolerance and shorten tool life.
