Hertel 45674785 Chucking Reamer 0.1305 in Solid Carbide

Product Description

The HERTEL 45674785 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining operations. With a reamer diameter of 0.1305 inches, an overall length of 2.5 inches, and a flute length of 0.75 inches, this tool delivers tight-tolerance sizing in small-bore applications. The 4-flute, straight-flute geometry in a right-hand cutting direction provides smooth, controlled material removal. The bright polished finish reduces friction and aids chip evacuation. Machinists and tool room technicians install this reamer in CNC machining centers, drill presses, and manual mills where bore accuracy and surface finish are critical.

This chucking reamer is suited for light to medium-duty reaming of small-diameter holes in ferrous and non-ferrous materials. The straight shank design seats directly into standard chucks and collet holders, making it compatible with a wide range of machine spindles. Typical applications include precision fixture work, close-tolerance assembly bores, and dowel pin hole finishing in tool and die, aerospace component, and general machining environments.

Key Features

• 0.1305 inch diameter for precision small-bore finishing
• Solid carbide construction for wear resistance and dimensional stability
• 4-flute straight-flute geometry with right-hand cutting direction
• Bright polished finish reduces friction and aids chip flow
• Straight shank fits standard chucks and collet holders
• Compact 2.5 inch overall length suited for close-clearance setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank chuck and collet systems on CNC and manual machining equipment requiring 0.1305 inch bore finishing capability.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the machine spindle before seating or removing the reamer. Secure the straight shank fully within the chuck or collet to the recommended grip depth to prevent pullout under cutting load. Verify spindle speed and feed rate against the material being reamed before running the tool.
