Value Collection SM0401020 Chucking Reamer 0.1020 in Hss

Product Description

The VALUE COLLECTION SM0401020 is a chucking reamer designed to finish-ream drilled or bored holes to a precise 0.1020-inch diameter. Machined from high-speed steel (HSS), this reamer delivers the hardness and edge retention needed for consistent hole sizing in ferrous and non-ferrous metals. The bright, uncoated finish suits general-purpose shop work where lubricated cutting is standard practice. With four straight flutes and a right-hand cutting direction, the tool removes material evenly and produces a smooth, dimensionally accurate bore wall. The straight-cylindrical shank seats securely in a drill chuck or collet for reliable concentricity during the cut.

This reamer is suited for machine shop, toolroom, and production floor use where accurate hole tolerance is required prior to fitting pins, bushings, or precision fasteners. It is sized for light material removal following a drill pass, typically finishing holes in the 0.1000-inch to 0.1499-inch diameter range. Machinists, toolmakers, and CNC operators working on fixtures, dies, and close-tolerance assemblies are the primary users.

Key Features

• 0.1020-inch finished hole diameter for close-tolerance work
• High-speed steel (HSS) construction for hardness and edge retention
• Four straight flutes for even material removal and smooth bore finish
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank for positive chuck or collet grip
• Bright, uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a standard drill chuck or collet capable of holding a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists and toolroom professionals. Ensure the workpiece is securely fixtured and the spindle is at an appropriate low RPM with cutting fluid applied before engaging the reamer. Never attempt to rotate a chucking reamer by hand to clear chips — retract the tool with the spindle running to avoid edge damage. Inspect the shank seating in the chuck or collet before each use to confirm concentricity.
