Walter-titex 5072440 Chucking Reamer 3.98mm 6 Flute Cobalt

Product Description

The WALTER-TITEX 5072440 is a straight-cylindrical shank chucking reamer designed for precision hole finishing in metalworking applications. Built from cobalt steel with a bright, uncoated finish, it delivers consistent sizing performance in demanding materials. The reamer measures 3.98mm in diameter (0.1567 decimal inch) with a 75mm overall length and a 19mm flute length. Six left-hand spiral flutes with right-hand cutting direction provide smooth chip evacuation and accurate bore geometry. The diameter tolerance of plus 0.004mm supports close-tolerance hole finishing work. Licensed machinists and toolroom technicians are the primary installers of this type of precision tooling.

This chucking reamer is suited for precision boring and hole-sizing operations in machine shop, toolroom, and production environments. It is sized for the 3.00mm to 4.00mm diameter range and is appropriate for use in CNC machining centers, manual mills, and drill presses equipped with a chuck or collet capable of holding a straight-cylindrical shank. The cobalt steel construction makes it a practical choice when working with harder ferrous metals or higher-heat cutting conditions compared to standard high-speed steel reamers.

Key Features

• 3.98mm (0.1567 inch) reamer diameter with plus 0.004mm tolerance for close-tolerance hole finishing
• Cobalt steel construction for improved heat and wear resistance over standard HSS
• Six left-hand spiral flutes with right-hand cutting direction for smooth chip flow
• Bright, uncoated finish suitable for a wide range of metalworking applications
• Straight-cylindrical shank for compatibility with standard chucks and collets
• 19mm flute length provides adequate cutting depth for typical through and blind hole operations

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool equipped with a chuck or collet sized to accept a straight-cylindrical shank in the 3.00mm to 4.00mm diameter range.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with precision hole-finishing operations. Ensure the machine spindle is fully stopped and the workpiece is securely fixtured before mounting or changing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Inspect the reamer for chipping or wear before each use and never force the tool through undersized stock.
