Value Collection SM0409970 Chucking Reamer Hss 0.9970 in

Product Description

The VALUE COLLECTION SM0409970 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.9970-inch diameter. The bright, uncoated finish reflects the base HSS material without any additional coating treatment. With an overall length of 10.5 inches and a straight flute geometry, this reamer is suited for through-hole and blind-hole applications where tight dimensional tolerances are required. It mounts via a straight-cylindrical shank and is compatible with standard drill chucks and collet holders. Right-hand cutting direction is standard. Machinists and toolroom technicians are the primary installers and operators of this tool.

This chucking reamer is appropriate for metalworking operations in machine shops, maintenance facilities, and production environments. It covers the 0.7000 to 0.9999-inch reamer diameter range, making it a practical choice when finish-sizing holes in that bracket. The 2.75-inch flute length provides adequate chip clearance for most standard-depth hole finishing operations in ferrous and non-ferrous materials.

Key Features

• 0.9970-inch reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Straight flute geometry for clean cutting action in through and blind holes
• Bright, uncoated finish — no coating buildup affecting dimensional accuracy
• Straight-cylindrical shank for compatibility with standard drill chucks and collet holders
• Right-hand cutting direction, standard for conventional reaming operations

Compatibility

Designed as an OEM-style replacement-grade chucking reamer for use in machine tools equipped with standard drill chucks or collet systems accepting a straight-cylindrical shank in the 0.9970-inch diameter class.

Installation Notes

This tool is intended for use by machinists operating drill presses, lathes, or milling machines with appropriate chuck or collet toolholding. Secure the straight-cylindrical shank firmly in the chuck or collet before operation and verify runout with an indicator before cutting. Always bring the reamer into the hole at a low feed rate to avoid chatter and oversize conditions. Ensure the machine spindle is fully stopped before removing or inspecting the tool.
