Value Collection SM0404680 Chucking Reamer 0.4680 in Hss

Product Description

The VALUE COLLECTION SM0404680 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.4680-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks and collet-style toolholders, making it straightforward to integrate into both manual and CNC drilling operations. Right-hand cutting geometry produces clean, burr-light bores when used at appropriate speeds and feeds for the workpiece material.

This reamer is suited for machine-shop, toolroom, and maintenance applications where finish-bore sizing is required after drilling or rough-boring. Typical use cases include bearing seat preparation, bushing installation, and dowel-pin hole sizing. It is appropriate for use in milling machines, drill presses, and lathes. The 0.4680-inch diameter falls within the 0.4000-to-0.4999-inch decimal-inch reamer range, covering a common mid-range bore size encountered in general metalworking and repair work.

Key Features

• 0.4680-inch finished bore diameter for precise hole sizing
• HSS construction provides good wear resistance across common workpiece materials
• Straight flute design suited for through-holes and shorter blind bores
• Bright, uncoated finish — no coating to flake or affect close tolerances
• Right-hand cutting direction for standard machine spindle rotation
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a standard chucking reamer for use in drill presses, milling machines, and lathes equipped with drill chucks or collet toolholders accepting a straight-cylindrical shank at the 0.4680-inch diameter range.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians. Secure the shank fully in the chuck or collet and verify runout before cutting. Always apply appropriate cutting fluid for the workpiece material and reduce spindle speed relative to the preceding drill operation. Never ream an undersized pilot hole — follow standard reamer allowance guidelines for the diameter and material being machined.
