Hertel 72033202 Chucking Reamer 0.3200 in Hss 6 Flute

Product Description

The HERTEL 72033202 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.3200-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this 6-flute reamer delivers clean, accurate bores in a wide range of metals and plastics. The straight-cylindrical shank seats securely in drill chucks, collets, and floating holders. At 6 inches overall length with a 1.5-inch flute length, it is well suited for through-holes and shallow blind-hole finishing in production and maintenance machining environments. Right-hand cutting direction follows standard spindle rotation. No special setup is required beyond proper chuck runout alignment and appropriate cutting fluid for the workpiece material.

This reamer is used in machine shop, toolroom, and maintenance repair operations where a reamed finish and close-diameter tolerance are required. It is appropriate for use in CNC machining centers, manual knee mills, drill presses, and turret lathes. The 0.3200-inch diameter falls within the 0.3000- to 0.3499-inch range, making it a common size for pin-fit bores, bearing seats, and dowel-hole finishing across general industrial and production applications. Licensed machinists and tool-and-die technicians are the primary users.

Key Features

• 0.3200-inch finished-bore diameter with HSS construction for extended tool life in ferrous and non-ferrous materials
• 6 straight flutes provide smooth cutting action and good chip evacuation in through-hole applications
• Bright, uncoated finish — compatible with most cutting fluids and suitable for re-sharpening
• Straight-cylindrical shank fits standard drill chucks, ER collets, and floating reamer holders
• Right-hand cutting direction matches standard CNC and manual spindle rotation
• 6-inch overall length with 1.5-inch flute length balances reach and rigidity for typical production hole depths

Compatibility

Designed as an OEM-style chucking reamer for use wherever a 0.3200-inch straight-flute HSS reamer is specified; fits standard drill chucks and collet systems accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists following standard shop safety and toolholding procedures. Power down and lock out the spindle before inserting or removing the reamer from the holder. Verify chuck or collet runout before reaming to maintain diameter tolerance; excessive runout will oversize the bore. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
