Value Collection 144429602790000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602790000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2790-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing and smooth surface finish in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, and the 6-flute geometry distributes cutting load evenly for stable, chatter-free performance. Machinists and toolroom technicians reach for this style of reamer when a drilled hole needs to be brought to a close-tolerance final diameter.

This chucking reamer is suited for use in drill presses, lathes, milling machines, and CNC machining centers where a floating or rigid holder maintains alignment between the tool and the existing hole. Typical applications include finish-reaming clearance holes, dowel pin holes, and bearing bores in production and maintenance machining environments. The right-hand cutting direction is standard for conventional clockwise-spindle operation.

Key Features

• 0.2790-inch finished hole diameter, within the 0.2500 to 0.2999-inch reamer diameter range
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• 6-flute straight configuration for even load distribution and smooth bore finish
• Bright, uncoated finish — ready to use out of the package, resharpenable
• Straight-cylindrical shank for compatibility with standard drill chucks and collet systems
• Right-hand cutting direction for use with conventional clockwise-rotation spindles

Compatibility

Designed as a standard chucking reamer for use in any machine tool spindle accepting a straight-cylindrical shank, including drill presses, engine lathes, knee mills, and CNC machining centers with an appropriate chuck or collet holder.

Installation Notes

Chucking reamers are installed and removed by a qualified machinist or toolroom technician with the machine spindle fully stopped and locked out per applicable machine-safety procedures. Ensure the shank is fully seated and securely clamped in the chuck or collet before starting the spindle. Reaming stock allowance, cutting speed, feed rate, and cutting fluid selection should follow standard HSS reaming practices for the workpiece material. Do not reverse spindle direction while the reamer is engaged in a hole.
