Value Collection 24006450 Chucking Reamer 0.645 in Solid Carbide

Product Description

The VALUE COLLECTION 24006450 is a solid carbide chucking reamer designed to bring finish-bored holes to tight dimensional tolerance in production and job-shop environments. It carries a 0.645-inch nominal diameter with a tolerance of +0.0003 to -0.0000 inches, making it suitable for precision fits. The 9-inch overall length and straight shank allow it to seat in a standard drill chuck or collet without additional adapters. Six straight flutes with a bright polished finish reduce chip packing and help maintain bore finish. Right-hand cutting direction is standard for conventional CNC and manual machine setups. Machinists and tool-and-die technicians are the typical end users.

This reamer is used in holemaking operations where a drilled or bored hole requires a final pass to achieve close dimensional accuracy and smooth surface finish. It is suited for ferrous and non-ferrous workpieces in vertical machining centers, knee mills, and drill presses. The 2.25-inch flute length accommodates moderate-depth through-holes and blind holes with adequate chip clearance. Its straight flute geometry is well matched to shorter-chipping materials. The bright uncoated carbide surface is appropriate for applications where coatings are not required or where re-sharpening is planned.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.645-inch diameter with +0.0003 to -0.0000 inch tolerance for close-tolerance fits
• 6 straight flutes with bright polished finish for smooth bore surface finish
• 9-inch overall length with 2.25-inch flute length for moderate-depth holes
• Straight shank for direct mounting in chucks or collets without additional tooling
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard straight-shank tool holders, drill chucks, and ER collet systems on CNC machining centers, knee mills, and drill presses that accept straight-shank tooling in the applicable diameter range.

Installation Notes

Chucking reamers are installed by machinists following standard machine tool lockout and spindle-stop procedures before changing tooling. Confirm shank seating and runout before cutting, as excessive runout will degrade bore tolerance and flute life. Feed rate and spindle speed should be set per established carbide reaming parameters for the specific workpiece material. Never use a reamer to remove more stock than its design allowance supports, as overloading will chip the flutes.
