Hertel 72010051 Chucking Reamer 0.1005 in Hss 4 Flute

Product Description

The HERTEL 72010051 is a high-speed steel (HSS) chucking reamer designed to finish-ream precision holes to a tight diameter tolerance of 0.1005 inches. It features a straight-cylindrical shank for secure chuck holding, four straight flutes, and a bright uncoated finish suited for a wide range of ferrous and non-ferrous materials. With an overall length of 3.5 inches and a flute length of 0.875 inches, this reamer is built for machine tool use in drill presses, lathes, and CNC machining centers where accurate hole sizing and smooth bore finish are required.

This chucking reamer is well suited for production and maintenance machining environments where precise hole tolerances are critical. It is used in general metalworking applications including tooling, fixture fabrication, and component manufacturing. The right-hand cutting direction is standard for conventional machine spindle rotation. The compact flute length makes it appropriate for shallow through-holes and blind-hole finishing operations where controlled material removal is needed.

Key Features

• 0.1005 inch finished diameter for precise hole sizing within the 0.1000 to 0.1499 inch diameter range class
• High-speed steel (HSS) construction provides toughness and wear resistance across common workpiece materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Four straight flutes with right-hand cutting direction for conventional machine operation
• Bright uncoated finish suitable for use with cutting fluids in standard machining operations
• 3.5 inch overall length with 0.875 inch flute length for shallow-hole finishing applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with drill chucks or collet systems that accept straight-cylindrical shank tooling.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Ensure the pre-drilled pilot hole is sized correctly — typically 0.003 to 0.005 inches undersize — before reaming to final diameter to avoid tool deflection or oversize bores.
