Walter-titex 5072872 Chucking Reamer 7.92mm 6 Flute Cobalt

Product Description

The WALTER-TITEX 5072872 is a solid cobalt steel chucking reamer designed to finish-ream drilled holes to a precise diameter of 7.92mm (0.3118 inches) with a tolerance of +0.005mm. The reamer features 6 spiral flutes with a left-hand spiral geometry and right-hand cutting direction, a combination that reduces chatter and produces a smooth bore finish. Overall length is 117mm (4.61 inches) with a 33mm (1.30 inches) flute length. The bright, uncoated finish is suitable for use in a wide range of ferrous and non-ferrous materials. This tool is installed and operated by machinists and tool-and-die professionals in precision machining environments.

This chucking reamer is used in CNC machining centers, knee mills, and drill presses where a straight-cylindrical shank is compatible with standard chuck toolholding. It is well suited for finishing holes in the 7.00mm to 8.00mm diameter range in production or maintenance machining operations. The straight-cylindrical shank allows quick changeover in collet chucks or drill chucks without specialized toolholding. Coolant-through is not supported, making it appropriate for conventional flood-coolant or dry-cutting setups.

Key Features

• 7.92mm (0.3118 inches) finished diameter with +0.005mm tolerance for precise hole sizing
• Cobalt steel construction provides heat and wear resistance over high-speed steel
• 6 left-hand spiral flutes with right-hand cut reduce chatter and improve surface finish
• Straight-cylindrical shank fits standard drill chucks and collet toolholding
• Bright, uncoated finish — no coating prep or recoating required
• 117mm (4.61 inches) OAL with 33mm (1.30 inches) flute length suits typical through-hole and shallow blind-hole applications

Compatibility

Designed as an OEM-style chucking reamer for use in machine tool spindles accepting a straight-cylindrical shank, compatible with applications requiring a finished hole diameter in the 7.00mm to 8.00mm range.

Installation Notes

This reamer is intended for use by trained machinists. Secure the straight-cylindrical shank firmly in a collet or drill chuck before operation, and ensure the spindle and workpiece are properly fixtured to prevent movement. Power down and lock out the machine before changing or inspecting the tool. Do not use this reamer as a drill — always pre-drill the hole to the appropriate undersize before reaming.
