Value Collection 144429604995000 Hss Chucking Reamer

Product Description

The VALUE COLLECTION 144429604995000 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.4995-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in drill chucks or collet holders, and the right-hand cutting direction is compatible with standard machine spindle rotation. With an 8-inch overall length and a 2-inch flute length, it provides adequate reach for typical machining depths while maintaining rigidity during the cut.

This chucking reamer is suited for machine-shop and production environments where hole tolerances require a finish-reaming pass after drilling. It is designated as a dowel pin reamer at 0.4995 D/P size, making it appropriate for preparing holes that accept standard 0.4995-inch dowel pins. Typical applications include CNC machining centers, drill presses, and manual mills running at reduced RPM for controlled material removal. Both job-shop machinists and maintenance technicians use this style of reamer when press-fit or slip-fit hole quality is required.

Key Features

• 0.4995-inch reamer diameter for precise dowel-pin and close-tolerance hole finishing
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Straight flute geometry suited for through-holes and short blind holes
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Right-hand cut, compatible with standard machine tool spindle rotation
• Straight-cylindrical shank for secure chuck or collet grip

Compatibility

Designed as a standard chucking reamer with a straight-cylindrical shank, compatible with drill chucks and collet systems sized to accept the shank diameter on drill presses, milling machines, and CNC machining centers.

Installation Notes

Chucking reamers are installed by licensed machinists or skilled tradespersons using a drill chuck or collet holder; ensure the shank is fully seated and the tool is concentric before operation. Power down and lock out the machine spindle before changing or securing the reamer. Run at reduced cutting speeds compared to drilling, and apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish. Inspect the reamer for edge wear or chipping before each use — a damaged cutting edge will produce oversized or rough holes.
