Hertel 2290526 Chucking Reamer 13/16 in Hss 8 Flute

Product Description

The HERTEL 2290526 is a straight-flute chucking reamer designed to finish-ream holes to a precise 13/16 inch (0.8125 inch) diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in production and maintenance machining operations. The reamer features 8 flutes for smooth cutting action and reduced chatter. With an overall length of 9-1/2 inches and a 2-1/2 inch flute length, it provides adequate reach for through-holes and blind-hole applications in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks and collet holders.

This chucking reamer is suited for machine shop, maintenance, and manufacturing environments where hole tolerances require a finishing pass after drilling. It is used in vertical mills, drill presses, and CNC machining centers equipped with a standard chuck or collet. Right-hand cutting direction makes it compatible with conventional clockwise spindle rotation. Typical applications include fixture bores, bearing seats, and precision-fit pin holes where a reamed surface finish is required.

Key Features

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck or collet capable of holding a straight-cylindrical shank in the 13/16 inch diameter range.

Installation Notes

Chucking reamers should be installed by a qualified machinist following standard machine tool safety procedures. Secure the shank fully in the chuck or collet and verify runout before cutting. Always apply appropriate cutting fluid for the workpiece material and operate at recommended reaming speeds, which are typically lower than drilling speeds. Power down and lock out the machine spindle before changing or adjusting the reamer.
