Value Collection 144429601885000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429601885000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.1885-inch diameter. The straight-flute geometry and bright uncoated finish make this reamer well suited for general-purpose hole finishing in ferrous and non-ferrous materials. At 4.5 inches overall length with a 1.125-inch flute length, it fits standard drill chucks and collet holders. This is an over-size reamer, designated 0.1885 O/S, making it appropriate when a finish bore slightly above nominal is required. Right-hand cutting direction matches conventional machine spindle rotation.

This chucking reamer is used in machine shop, maintenance, and production environments where close-tolerance hole finishing is required. The straight-cylindrical shank allows it to be held in standard drill press chucks, milling machine collets, CNC turning center live tooling, or tapping heads. Typical applications include finish-reaming clearance holes, bearing bores, and bushing fits in light to medium stock removal situations. It is sold individually and is appropriate for both manual machine operation and light CNC work.

Key Features

• 0.1885-inch finish diameter — over-size designation for bores requiring clearance above nominal
• High-speed steel (HSS) construction for general-purpose cutting in a wide range of materials
• Straight-cylindrical shank for compatibility with standard chucks and collets
• Straight-flute design suited for through-hole reaming in most common workpiece materials
• Bright uncoated finish — no coating buildup to affect diameter tolerance
• Right-hand cutting direction matches standard machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, milling machines, lathes, and CNC equipment equipped with straight-bore chucks or collets accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and removed by a licensed machinist or qualified tooling technician. Always power down and lock out the machine spindle before changing tooling. Secure the straight-cylindrical shank fully within the chuck or collet to the appropriate grip depth before tightening. Use recommended cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
