Hertel 45676236 Chucking Reamer 0.34 in Solid Carbide

Product Description

The HERTEL 45676236 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.34 inch diameter, 3.5 inch overall length, and a 1.25 inch flute length, this reamer delivers accurate, repeatable bore sizing in production and toolroom environments. The bright polished finish reduces friction and promotes smooth chip flow. Six straight flutes with a right-hand cutting direction make this tool well suited to CNC machining centers, manual mills, and drill press setups where close-tolerance holes are required. Machinists and toolroom technicians are the primary users.

This chucking reamer is intended for finish reaming operations in ferrous and non-ferrous metals where tight diameter tolerances are critical. The straight shank allows direct mounting in drill chucks, collet chucks, and floating reamer holders without the need for taper adapters. It is commonly used in production shops, job shops, and maintenance environments when drilling alone cannot hold the required bore tolerance. The 0.34 inch diameter falls within the 0.3000 to 0.3499 inch reamer diameter range category.

Key Features

• Solid carbide construction for extended tool life and rigidity in hard or abrasive materials
• Bright polished coating reduces friction and promotes clean chip evacuation
• Six straight flutes with right-hand cutting direction for smooth, accurate bore finishing
• Straight shank compatible with standard drill chucks and collet holders
• 0.34 inch reamer diameter for close-tolerance hole sizing
• Compact 3.5 inch overall length suited to tight-clearance setups

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard straight-shank tool holders across CNC and manual machining platforms requiring a 0.34 inch finish bore diameter.

Installation Notes

This reamer should be installed by a qualified machinist following standard tooling setup procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight shank firmly in the chuck or collet to the holder manufacturer's recommended clamping torque. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality.
