Hertel 72005002 Chucking Reamer 0.0500 in Hss 4-flute

Product Description

The HERTEL 72005002 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.0500-inch diameter. With a straight-cylindrical shank and four straight flutes in a right-hand cutting direction, it delivers accurate, smooth bore finishes in ferrous and non-ferrous materials. The bright, uncoated finish suits general-purpose reaming where coating is not required. At 2.5 inches overall length with a 0.5-inch flute length, this compact reamer is built for small-diameter precision work in production and maintenance machining environments. Machinists and toolroom technicians are the primary users.

This reamer is suited for small-diameter finish reaming applications in manual or CNC drill presses, milling machines, and lathes. The 0.0500-inch diameter falls within the 0.0500 to 0.0999-inch decimal-inch reamer range, making it appropriate for tight-tolerance holes in small mechanical components, jigs, fixtures, and tooling. Typical applications include final sizing of precision pin holes and dowel holes where surface finish and dimensional accuracy are critical.

Key Features

• 0.0500-inch reamer diameter for small, precision bore finishing
• HSS construction provides good toughness and wear resistance for general-purpose reaming
• 4 straight flutes with right-hand cutting direction for smooth, consistent stock removal
• Straight-cylindrical shank for secure chuck or collet holding
• Bright, uncoated finish suitable for a wide range of workpiece materials
• Compact 2.5-inch OAL with 0.5-inch flute length designed for shallow, small-diameter holes

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for standard drill press, milling machine, or lathe chuck and collet setups accepting a straight-cylindrical shank in the 0.0500-inch diameter class.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a suitable chuck or collet before use, and verify runout with an indicator when tolerance is critical. Always ream at appropriate speed and feed for the workpiece material, and use cutting fluid to extend tool life and improve surface finish. Never force a reamer into an undersized hole; confirm the pre-drilled hole is within the recommended undersize allowance for the target diameter.
