Hertel 72019953 Chucking Reamer 0.1995 in Hss 6 Flute

Product Description

The HERTEL 72019953 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. It measures 0.1995 inches in diameter with an overall length of 5 inches and a flute length of 1-1/4 inches. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With 6 straight flutes and a right-hand cutting direction, the tool delivers consistent material removal and a clean, accurately sized bore. The bright, uncoated finish suits general-purpose reaming in ferrous and non-ferrous materials. Machinists and toolroom technicians use this reamer to bring drilled or bored holes to a precise finished diameter within tight tolerances.

This chucking reamer is suited for manual and CNC machining operations in job shops, production facilities, and maintenance environments. It targets holes in the 0.1500 to 0.1999 inch diameter range and is well matched to operations on drill presses, lathes, and machining centers where a straight-cylindrical shank is preferred. The 1-1/4 inch flute length accommodates typical through-hole and shallow blind-hole applications encountered in general machine work.

Key Features

• 0.1995 inch reamer diameter for precise hole finishing in the 0.1500-0.1999 inch range
• HSS tool material provides toughness and wear resistance for general-purpose machining
• 6 straight flutes with right-hand cutting direction for smooth, accurate material removal
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Bright, uncoated finish suitable for use with most cutting fluids and standard shop lubricants
• 5 inch overall length with 1-1/4 inch flute length suits typical through-hole and shallow blind-hole work

Compatibility

Designed as a standard chucking reamer for use in drill chucks and collet holders accepting a straight-cylindrical shank; fits drill presses, lathes, and CNC machining centers set up for reaming operations in the 0.1500 to 0.1999 inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation, and verify shank runout before engaging the workpiece. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a worn or undersized holder, as excessive runout will compromise hole tolerance and accelerate tool wear.
