Value Collection 144429602940000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602940000 is a chucking reamer designed to finish-ream drilled or bored holes to a precise diameter of 0.2940 inches. Manufactured from high-speed steel (HSS), it delivers the hardness and wear resistance needed for accurate sizing in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, making it compatible with common machine setups. With 6 straight flutes and a bright, uncoated finish, this reamer is suited for machinists, tool-and-die workers, and maintenance technicians who need repeatable hole tolerance on the shop floor or in the field.

This chucking reamer is used in drilling and boring operations where a finish pass is required to bring a hole to final size. It is appropriate for use in manual milling machines, drill presses, and CNC machines with a rigid setup. The 0.2940-inch diameter places it in the 0.2500 to 0.2999-inch decimal inch range, a common size for dowel pin clearance holes, bearing fits, and precision fastener bores in light industrial and maintenance applications.

Key Features

• 0.2940-inch finished hole diameter for close-tolerance sizing
• High-speed steel (HSS) construction for hardness and edge retention
• 6 straight flutes for smooth, consistent material removal
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish — no coating buildup to affect diameter accuracy
• Right-hand cutting direction for standard machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, milling machines, and CNC machining centers that accept straight-cylindrical shank tooling in the 0.2500 to 0.2999-inch diameter class.

Installation Notes

Chucking reamers are installed by machinists or toolroom technicians in a rigid chuck or collet — avoid floating holders unless the application specifically requires it, as rigidity improves hole geometry. Power down and de-energize the machine spindle completely before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the desired surface finish. Follow shop-specific speed and feed guidelines for HSS reamers; excessive feed rate is the most common cause of premature edge wear.
