Hertel 45675949 Chucking Reamer 0.303 in Solid Carbide

Product Description

The HERTEL 45675949 is a solid carbide chucking reamer designed to produce accurate, finished-diameter holes in metalworking applications. With a reamer diameter of 0.303 inches and a bright polished finish, it delivers tight tolerances and smooth surface finishes in drilled or pre-bored holes. The straight flute geometry and right-hand cutting direction make it well-suited for use in CNC machining centers, drill presses, and manual lathes. Machinists and tool-and-die professionals reach for this style of reamer when hole size and finish are critical to fit and function. The 6-flute configuration distributes cutting load evenly and supports consistent chip evacuation across the 1.125-inch flute length.

This chucking reamer is intended for precision hole finishing in ferrous and non-ferrous metals. Its straight shank fits standard drill chucks and collet holders without modification. With an overall length of 3.25 inches and a flute length of 1.125 inches, it is sized for shallow-to-moderate depth reaming passes in production or job-shop environments. The solid carbide construction performs well in harder workpiece materials where high-speed steel tooling would wear prematurely.

Key Features

• Solid carbide construction for durability and wear resistance in hard materials
• 0.303-inch reamer diameter for tight-tolerance hole finishing
• 6 straight flutes with right-hand cutting direction for even load distribution
• Bright polished finish reduces friction and improves surface finish quality
• Straight shank fits standard chucks and collet holders without adapters
• 3.25-inch overall length with 1.125-inch flute length for controlled depth reaming

Compatibility

Designed as an OEM-style precision cutting tool for use in standard drill chucks and collet-style toolholders on CNC and manual machine tools requiring a straight shank reamer in the 0.300 to 0.3499-inch diameter range.

Installation Notes

Chucking reamers are installed and serviced by machinists and tool-and-die professionals. Always power down and lock out the machine spindle before changing tooling. Secure the straight shank fully in a properly sized chuck or collet to prevent runout. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality.
