Hertel 45674751 Chucking Reamer 0.1245 in Solid Carbide

Product Description

The HERTEL 45674751 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.1245 inch cutting diameter and a 4-flute, right-hand straight flute geometry, this reamer delivers accurate, smooth bore finishes in a single pass. The bright polished finish reduces friction and helps maintain dimensional accuracy over repeated use. At 2.25 inches overall length with a 0.625 inch flute length, the compact profile is well-suited for work in tight fixturing setups. A straight shank makes it compatible with standard drill chucks and collet holders used in CNC machining centers, drill presses, and manual milling machines.

This chucking reamer is intended for use in production and job-shop environments where tight hole tolerances are required. It is appropriate for reaming pre-drilled holes in ferrous and non-ferrous metals, plastics, and similar materials. The solid carbide construction makes it a strong choice for hard or abrasive workpiece materials where high-speed steel tools would wear prematurely. Machinists, tool-and-die makers, and CNC operators will find this reamer well-suited to applications demanding consistent finish quality and hole roundness on small-diameter bores.

Key Features

• 0.1245 inch cutting diameter for precise small-bore finishing
• Solid carbide construction for extended tool life in hard and abrasive materials
• 4-flute, right-hand straight flute design for smooth, accurate bore finishing
• Bright polished finish reduces cutting friction and aids chip evacuation
• Straight shank compatible with standard drill chucks and collet systems
• Compact 2.25 inch OAL suits close-quarters fixturing setups

Compatibility

Designed as a standard straight-shank chucking reamer for use in drill chucks and collet holders on CNC machining centers, drill presses, and manual milling machines where a 0.1245 inch finished bore diameter is required.

Installation Notes

Chucking reamers are installed and operated by machinists and CNC programmers following standard machining practices. Ensure the workpiece is securely fixtured and the spindle speed and feed rate are set per the tool manufacturer guidelines for the workpiece material before engaging the cut. Always pre-drill the hole to the appropriate undersize before reaming to avoid tool deflection or overloading. Inspect the shank seating in the chuck or collet for runout before production use.
