Value Collection 144429603270000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603270000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3270-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance on a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With 6 flutes and a right-hand cutting direction, this reamer produces smooth, accurate bores suitable for close-tolerance fitting work in machine shops, maintenance environments, and production floor applications.

This reamer is suited for use in drill presses, lathes, CNC machining centers, and manual milling setups where a 0.3270-inch finished bore is required. It falls within the 0.3000 to 0.3499-inch reamer diameter range and is appropriate for finish-reaming operations that follow a drilling or rough-boring step. Machinists, tool-and-die makers, and maintenance technicians typically reach for this tool when hole tolerance and surface finish cannot be achieved by drilling alone.

Key Features

• 0.3270-inch finished bore diameter with straight-cylindrical shank for universal chuck compatibility
• High-speed steel (HSS) construction provides durability across a broad range of workpiece materials
• 6-flute geometry improves surface finish and distributes cutting load evenly
• Right-hand cutting direction for conventional forward-feed reaming operations
• Bright, uncoated finish — no coating thickness to account for when holding tight tolerances
• Not an over/under-size or dowel pin reamer — standard nominal diameter

Compatibility

Designed as a standard chucking reamer for use in any machine tool setup accepting a straight-cylindrical shank; compatible with drill chucks and collet holders sized to grip the shank diameter.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-and-die technicians. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Always ream at lower RPM and higher feed rates than drilling to avoid chatter and premature wear. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish.
