Hertel 45675303 Chucking Reamer 0.216 in Solid Carbide

Product Description

The HERTEL 45675303 is a solid carbide chucking reamer designed for precision hole finishing in metal and other hard materials. With a reamer diameter of 0.216 inches and a 3-inch overall length, this tool delivers tight-tolerance sizing in applications where drilled holes require accurate final dimensions. The straight flute geometry and right-hand cut make it well-suited for most conventional reaming operations. Four flutes provide consistent surface finish and efficient chip evacuation. The bright, uncoated carbide construction maintains edge integrity across a range of workpiece materials without the added complexity of coated tooling.

This chucking reamer is intended for use in drill presses, lathes, CNC machining centers, and manual machine setups where a straight-shank tool is required. The 1-inch flute length accommodates typical through-hole and blind-hole reaming depths in this diameter range. It is appropriate for job shop, maintenance, and production environments where precise hole sizing is required in steel, aluminum, cast iron, and similar materials.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 0.216-inch reamer diameter for precise hole finishing in the 0.2000 to 0.2499-inch diameter range
• Four straight flutes with right-hand cut for consistent chip flow and surface finish
• Bright, uncoated finish suitable for use with or without cutting fluid
• Straight shank for direct chuck mounting on standard toolholding equipment
• 1-inch flute length accommodates typical reaming depths at this diameter

Compatibility

Designed as a standard chucking reamer for use with straight-shank compatible drill chucks and collet systems on drill presses, lathes, and machining centers requiring a 0.216-inch finished hole diameter.

Installation Notes

Chucking reamers should be installed by a qualified machinist or tooling technician following standard shop safety procedures. Secure the straight shank firmly in the chuck or collet before operation and verify runout with a dial indicator where tolerances are critical. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never force a reamer through an undersized hole — ensure the pre-drilled pilot hole is within the recommended stock allowance for the reamer diameter.
