Value Collection 144429608740000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429608740000 is a chucking reamer designed to finish-ream holes to a precise 0.8740-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this tool delivers consistent dimensional accuracy in production and maintenance machining operations. The straight-cylindrical shank mounts directly in a drill press, lathe, or milling machine chuck. With 10 straight flutes and a right-hand cutting direction, it removes material cleanly and uniformly, leaving a finished bore suitable for close-tolerance fits. At 0.5 pounds, the tool is easy to handle during setup and changeover.

This reamer is suited for metalworking applications where holes require final sizing to 0.8740 inches after drilling or boring. It is commonly used in job shops, maintenance facilities, and production environments for sizing bearing bores, bushing seats, and precision-fit pin holes. The straight flute geometry performs well in through-holes and short blind holes in ferrous and non-ferrous materials. A licensed machinist or skilled toolroom technician typically performs this operation on conventional or CNC machine tools.

Key Features

• 0.8740-inch finished bore diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 10 straight flutes for smooth, uniform material removal
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collets without an adapter
• Bright/uncoated finish — no coating interference in light or moderate cutting duty

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 0.8740-inch diameter range.

Installation Notes

A qualified machinist should mount the reamer securely in a suitable chuck or collet before use. The workpiece hole should be pre-drilled or bored to within a few thousandths of the finished diameter before reaming. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never reverse spindle direction while the reamer is engaged in the bore.
