Hertel 45675519 Chucking Reamer 0.239 in Solid Carbide

Product Description

The HERTEL 45675519 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.239 inch cutting diameter and a bright polished finish, this reamer delivers tight dimensional tolerances on drilled or bored holes. The straight flute geometry and right-hand cutting direction make it well suited for through-hole and blind-hole finishing operations on ferrous and non-ferrous materials. At 3 inches overall length with a 1 inch flute length and straight shank, it mounts directly into standard drill chucks or collet holders on lathes, drill presses, and CNC machining centers.

This chucking reamer is used in precision machining environments where hole size accuracy and surface finish are critical. Typical applications include fixture and tooling shops, production machining, and maintenance repair operations requiring close-tolerance hole sizing. The solid carbide construction provides rigidity and wear resistance that makes it appropriate for harder workpiece materials and higher-volume runs compared to HSS alternatives.

Key Features

• 0.239 inch cutting diameter falls within the 0.2000 to 0.2499 inch reamer diameter range
• Solid carbide construction for enhanced rigidity and wear resistance
• Bright polished finish reduces friction and aids chip evacuation
• 4 straight flutes with right-hand cutting direction
• Straight shank for compatibility with standard drill chucks and collet holders
• 3 inch overall length with 1 inch flute length for compact reach in confined setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank tool holders, drill chucks, and collet chuck systems on lathes, drill presses, and machining centers accepting straight-shank tooling in the 0.2390 inch diameter class.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Secure the straight shank firmly in a calibrated drill chuck or collet holder before operation, and verify runout is within acceptable limits for the tolerance required. Always bring the spindle to the appropriate feed and speed for the workpiece material before engaging the reamer. Use appropriate cutting fluid to extend tool life and maintain surface finish quality.
