Value Collection 144429600400000 Chucking Reamer Letter D Hss

Product Description

The VALUE COLLECTION 144429600400000 is a straight-flute chucking reamer designed to finish-ream holes to a precise Letter D diameter of 0.2460 inches. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With an overall length of 6 inches and a 1.5-inch flute length, this reamer suits bench-top drill presses, CNC lathes, and manual turret lathes where a right-hand cutting action is required. Machinists and toolroom operators reach for this reamer when bore tolerance and surface finish matter.

This chucking reamer is used in production and job-shop machining environments to bring drilled or bored holes to final size. It is appropriate for through-holes and blind holes where a straight-flute geometry provides adequate chip clearance. Typical applications include dowel-pin hole finishing, bushing bores, and precision fit work in mild steel, aluminum, brass, and cast iron. The Letter D size falls within the 0.2000 to 0.2499 inch diameter range, making it a common selection for close-tolerance shaft and pin fits in light manufacturing and maintenance machining.

Key Features

• Straight flute geometry supports right-hand cutting with predictable chip flow
• Bright, uncoated finish provides a consistent cutting edge without coating build-up
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 6-inch overall length provides reach and rigidity in drill press and lathe setups

Compatibility

Designed as an OEM-style replacement or direct-fit chucking reamer for use in any machine tool accepting a straight-cylindrical shank reamer in the Letter D size range.

Installation Notes

A qualified machinist or toolroom technician should install and operate this reamer. Power down and lock out the machine before loading the reamer into the chuck or collet. Ensure the shank is fully seated and the holding device is properly tightened before beginning the cut. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
