Walter-titex 5072441 Chucking Reamer 3.99mm 6 Flute Cobalt

Product Description

The WALTER-TITEX 5072441 is a 6-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from cobalt steel with a bright, uncoated finish, it delivers consistent dimensional accuracy when sizing bored or drilled holes to tight tolerances. The reamer features a straight-cylindrical shank for secure chuck engagement and a spiral flute geometry with left-hand spiral direction paired with right-hand cutting action. At 3.99mm in diameter with a reamer diameter tolerance of plus 0.004mm, this tool is suited for machinists and toolroom professionals who require controlled final-pass sizing.

This chucking reamer is intended for bench, drill press, or CNC lathe applications where a precise 3.99mm finished hole diameter is required. The 19mm flute length provides adequate chip clearance in moderate-depth holes, while the 75mm overall length accommodates standard chucking setups. It is appropriate for use in ferrous and high-strength alloy materials where cobalt steel provides the necessary hardness and heat resistance. Typical users include machinist shops, toolrooms, and precision manufacturing environments.

Key Features

• 3.99mm reamer diameter with a tight tolerance of plus 0.004mm for precision hole finishing
• Cobalt steel construction for improved heat resistance and durability in hard materials
• 6-flute spiral design provides smooth cutting action and efficient chip evacuation
• Left-hand spiral with right-hand cutting direction reduces chatter and improves surface finish
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish suitable for use with cutting fluids in general-purpose machining

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard drill chucks and collet systems accepting a straight-cylindrical shank in the 3mm to 4mm reamer diameter range.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom technician. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout with a dial indicator when tolerances are critical. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Power down and lock out the machine spindle before changing or inspecting the reamer.
