Hertel 45676848 Chucking Reamer 0.445 in Solid Carbide

Product Description

The HERTEL 45676848 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a 0.445-inch diameter and six straight flutes, it delivers accurate, repeatable hole sizing in ferrous and non-ferrous materials. The bright, uncoated carbide construction provides rigidity and edge retention for close-tolerance work. Overall length is 4 inches with a 1.375-inch flute length and a straight cylindrical shank for secure chuck or collet holding. Right-hand cutting direction. Machinists and tool-room operators use this reamer to bring drilled or bored holes to finished diameter with consistent surface finish.

This chucking reamer is suited for CNC machining centers, manual mills, and drill presses where a straight-shank tool can be held in a drill chuck, collet, or end mill holder. It is appropriate for production and job-shop environments requiring tight hole tolerances. The solid carbide construction makes it well suited for harder workpiece materials and higher spindle speeds compared to HSS alternatives. It is sold individually and intended for professional machining applications.

Key Features

• 0.445-inch finished hole diameter with six straight flutes for smooth, accurate reaming
• Solid carbide construction for rigidity and extended edge life
• Bright, uncoated finish suitable for a wide range of workpiece materials
• Straight cylindrical shank fits standard drill chucks, collets, and holders
• Right-hand cutting direction, standard configuration for machine reaming
• 4-inch overall length with 1.375-inch flute length for accessibility in typical setups

Compatibility

Designed as a machine-held chucking reamer for use in CNC machining centers, manual milling machines, and drill presses equipped with a drill chuck or collet capable of holding a straight cylindrical shank tool.

Installation Notes

This tool is installed and used by machinists and toolroom professionals. Secure the straight shank firmly in a properly sized collet, drill chuck, or holder before operation, and verify runout is within acceptable limits for the tolerance required. Always reduce feed rate and use appropriate cutting fluid when reaming to maximize tool life and hole finish. Power down and de-energize the machine spindle before changing or adjusting tooling.
