Value Collection 144429603140000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603140000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3140-inch diameter. The straight-flute geometry and bright, uncoated finish are suited for use in softer ferrous and non-ferrous materials where a clean, accurate bore is required. With six flutes and a right-hand cutting direction, this reamer produces a smooth surface finish in a single pass. The straight-cylindrical shank mounts directly in standard drill chucks, collets, or machine spindles. Machinists and tool-and-die professionals use this style of reamer in manual mills, drill presses, and CNC machines where tight hole tolerances are needed.

This chucking reamer is intended for general machine-shop and maintenance applications requiring precise hole sizing in the 0.3000 to 0.3499-inch decimal diameter range. It is well suited for fixture work, jig plates, dowel-pin fit preparation, and any production or repair operation where a reamed finish bore is specified. The straight-cylindrical shank provides broad compatibility with standard toolholding systems found in most shop environments.

Key Features

• 0.3140-inch reamer diameter for precise finish boring in the 0.3000 to 0.3499-inch diameter range
• HSS tool material delivers good wear resistance across a range of workpiece materials
• Six straight flutes for consistent material removal and smooth hole finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish — no coating buildup to affect critical diameter tolerance
• Straight-cylindrical shank seats securely in drill chucks, ER collets, and similar holders

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks, collets, and machine spindles that accept a straight-cylindrical shank in the appropriate diameter range.

Installation Notes

Chucking reamers are installed by qualified machinists or tool-and-die technicians. Ensure the machine is fully powered down and the spindle is at rest before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent runout, which directly affects hole-size accuracy. Always apply appropriate cutting fluid for the workpiece material and never run a reamer in reverse, as this will dull the cutting edges.
