Value Collection SM0408780 Chucking Reamer 0.8780 in Hss

Product Description

The VALUE COLLECTION SM0408780 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.8780-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent sizing in ferrous and non-ferrous metals across general machining operations. The straight-cylindrical shank seats securely in drill chucks, collets, and floating reamer holders. With a 10-inch overall length and a 2-5/8-inch flute length, it provides adequate reach for standard workpiece depths while keeping deflection manageable. Right-hand cutting direction follows conventional reaming practice. Weight is 0.8 pounds.

This chucking reamer is suited for machine-shop and production environments where hole tolerances require a finishing pass after drilling. Typical applications include through-hole and blind-hole reaming on manual mills, CNC machining centers, drill presses, and lathes. It is appropriate for job shops, toolrooms, and maintenance machining where a reliable HSS reamer in the 0.7000 to 0.9999-inch diameter range is needed. No special adapters are required when the shank is held in a standard drill chuck or precision collet of the appropriate size.

Key Features

• 0.8780-inch reaming diameter for precise, repeatable hole sizing
• HSS construction provides adequate hardness and toughness for general-purpose reaming
• Straight flute geometry suits most ferrous and non-ferrous materials
• Bright uncoated finish — no coating buildup to affect tolerance
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Right-hand cutting direction for use with conventional spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machine tools accepting a straight-cylindrical shank in the 0.8780-inch diameter class, consistent with the 0.7000 to 0.9999-inch reamer diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with reaming operations. Power down and lock out the machine spindle before mounting or removing the tool. Secure the straight-cylindrical shank firmly in a drill chuck or collet to the manufacturer-specified holding depth to prevent slippage under cutting load. Apply appropriate cutting fluid for the workpiece material, and never exceed the recommended feed and speed for the diameter and material being reamed.
