Value Collection SM0406410 Chucking Reamer 0.6410 in Hss

Product Description

The VALUE COLLECTION SM0406410 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.6410-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable performance across a wide range of ferrous and non-ferrous workpiece materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With a 9-inch overall length and a 2.25-inch flute length, this reamer suits bench-top lathes, drill presses, and CNC machining centers where controlled hole sizing is required. Six right-hand cutting flutes distribute cutting load evenly and help produce a smooth, dimensionally accurate bore.

This reamer is appropriate for production and maintenance machining environments where hole tolerances must be held tightly after drilling. Typical applications include finishing bearing bores, pin holes, and bushing seats in job-shop and toolroom settings. It is sized within the 0.5000-to-0.6999-inch decimal-inch reamer diameter range, making it a practical choice for medium-diameter finishing work on mild steel, aluminum, brass, and similar machinable materials.

Key Features

• 0.6410-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across common workpiece materials
• 6 straight flutes with right-hand cutting direction for smooth material removal
• Bright, uncoated finish suitable for general-purpose reaming operations
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• 9-inch overall length provides clearance for deeper setups on lathes and drill presses

Compatibility

Designed as a general-purpose chucking reamer for use with standard drill chucks, ER collet holders, and similar straight-shank toolholding systems on lathes, drill presses, and machining centers.

Installation Notes

Machinists and toolroom technicians should ensure the machine spindle is fully stopped and the workpiece is securely fixtured before mounting or removing the reamer. Use a proper cutting fluid or lubricant appropriate for the workpiece material to extend tool life and improve surface finish. Confirm shank seating and chuck tightness before initiating the cut. Never attempt to hand-turn the reamer backward against the cutting direction, as this can dull the flute edges.
