Value Collection 144429607860000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429607860000 is a chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. Built from high-speed steel (HSS), it delivers the hardness and wear resistance needed for sizing holes in ferrous and non-ferrous metals. The straight flute geometry and 10-flute configuration produce a smooth bore finish and distribute cutting load evenly across the tool. The straight-cylindrical shank mounts directly into drill press chucks, milling machine collets, or CNC tool holders without adapters. This reamer is suited for shop environments where tight hole-diameter control is required in production or maintenance applications.

This chucking reamer is used in machine shops, maintenance facilities, and manufacturing environments where holes must be brought to a finished diameter with close dimensional accuracy. The 0.7860-inch diameter targets finish-reaming of pre-drilled or bored holes in the 0.7000 to 0.9999-inch diameter range. Typical applications include bearing-seat preparation, bushing installation, and precision fit work on ferrous alloys, cast iron, aluminum, and brass. It is installed by machinists and tool-and-die technicians using standard machine tool setups.

Key Features

• 0.7860-inch finished diameter for precise hole sizing
• High-speed steel (HSS) construction for hardness and wear resistance
• 10 straight flutes for smooth finish and even cutting load distribution
• Straight-cylindrical shank compatible with standard drill press and milling machine chucks and collets
• Not configured as a dowel pin reamer or over/under size reamer — standard on-size application

Compatibility

Designed as a standard chucking reamer for finish-reaming operations on pre-drilled or bored holes requiring a 0.7860-inch final diameter. Fits any machine tool spindle or chuck that accepts a straight-cylindrical shank of the corresponding diameter.

Installation Notes

Chucking reamers are installed by machinists in drill presses, milling machines, or CNC machining centers. Always ensure the workpiece is securely fixtured and the spindle is powered down before loading or unloading the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. The pre-drilled or bored hole should be sized to standard reaming allowance before the reamer is applied.
