Value Collection 144429601200000 Chucking Reamer Letter L

Product Description

The VALUE COLLECTION 144429601200000 is a straight-flute chucking reamer designed to finish-ream holes to a precise Letter L diameter of 0.290 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate bores in a wide range of workpiece materials. The straight-cylindrical shank seats securely in standard drill chucks, collet holders, and floating reamer holders. With an overall length of 6 inches and a 1.5-inch flute length, this tool is well suited for through-holes and shallow blind bores in production and maintenance machining environments. Right-hand cutting geometry keeps feed forces predictable on manual and CNC equipment alike.

This chucking reamer is used in machine shop, toolroom, and maintenance-repair-operations (MRO) settings where final hole size, roundness, and surface finish are critical. Typical applications include sizing holes for dowel pins, bushings, and close-tolerance fasteners in ferrous and non-ferrous materials. The Letter L designation places the nominal diameter at 0.290 inches, falling within the 0.2500 to 0.2999 inch diameter range. Machinists and tool-and-die technicians are the primary users of this style of reamer.

Key Features

• Letter L diameter — 0.290 inches nominal for precise hole sizing
• HSS construction provides good wear resistance across a broad range of materials
• Straight flute geometry suits most general-purpose reaming applications
• Bright, uncoated finish works well with cutting fluids and standard MRO lubricants
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for use in standard forward-rotating spindles

Compatibility

Designed as an OEM-style replacement chucking reamer for use in any machine tool spindle accepting a straight-cylindrical shank within the applicable diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists using drill presses, lathes, milling machines, or CNC machining centers. Always secure the shank fully in the chuck or collet before operation and verify runout with an indicator where tight tolerances are required. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill the hole to within approximately 0.005 to 0.015 inches of final size before reaming to avoid overloading the flutes.
