Hertel 72037518 Chucking Reamer 0.7510 in Hss 8 Flute

Product Description

The HERTEL 72037518 is a straight-flute chucking reamer designed to finish-ream holes to a precise 0.7510-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bores in a wide range of ferrous and non-ferrous materials. The reamer features 8 flutes and a right-hand cutting direction, providing smooth chip evacuation and consistent surface finish. With a 9.5-inch overall length and a 2.5-inch flute length, it is suited for moderate-depth through-holes. The straight-cylindrical shank seats directly in standard drill chucks or collet holders. Machinists, tool-and-die makers, and production floor operators use this reamer for sizing holes to close tolerances in manual and CNC-controlled machine tools.

This reamer is appropriate for shop-floor and job-site applications where a hole must be brought to a precise finished diameter after drilling. Typical use cases include reaming bearing bores, dowel-pin holes, bushing seats, and precision-fit shaft clearances. The 0.7510-inch diameter falls within the 0.7000 to 0.9999-inch decimal-inch reamer range, making it a standard selection for mid-size hole finishing. It is used on drill presses, lathes, milling machines, and CNC machining centers. The HSS construction handles interrupted cuts and moderate feeds without chipping under normal machining conditions.

Key Features

• 0.7510-inch finished hole diameter for close-tolerance bore sizing
• 8 straight flutes with right-hand cutting direction for smooth, consistent chip flow
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with drill chucks and standard collet systems
• 9.5-inch overall length with 2.5-inch flute length for moderate-depth hole applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with drill chucks or collet holders sized to accept a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by qualified machinists following standard machine-shop practices. Secure the shank fully in the chuck or collet and verify runout before cutting. Always apply an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Pre-drill the hole to within a few thousandths of the finished diameter before reaming — attempting to remove excess stock in a single reaming pass will accelerate tool wear and compromise hole quality.
