Hertel 72010457 Chucking Reamer 0.1045 in Hss 4 Flute

Product Description

The HERTEL 72010457 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer holds a 0.1045-inch diameter and delivers a right-hand cutting action across 4 straight flutes. The straight-cylindrical shank seats securely in standard chuck collets, making it a reliable choice for drill press, lathe, or CNC applications where close-tolerance hole sizing is required. Machinists and tool-and-die professionals reach for this type of reamer when a drilled hole needs to be brought to a precise final diameter with consistent surface finish.

This reamer is suited for light-material removal in ferrous and non-ferrous metals where a hole has been pre-drilled near finish size. With an overall length of 3.5 inches and a flute length of 0.875 inches, it fits standard toolholding setups found in job shops, maintenance facilities, and production machining environments. The compact flute length makes it appropriate for through-holes and shallow blind holes in parts requiring tight dimensional tolerances.

Key Features

• 0.1045-inch finished diameter for precision hole sizing
• HSS construction provides good wear resistance across common workpiece materials
• 4 straight flutes with bright uncoated finish for clean chip evacuation
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction compatible with standard spindle rotation
• Compact 0.875-inch flute length suitable for shallow and through-hole applications

Compatibility

Designed as an OEM-style chucking reamer for use in drill press, lathe, or CNC toolholding systems that accept a straight-cylindrical shank in the applicable diameter range.

Installation Notes

Chucking reamers are installed and serviced by machinists and tool-and-die technicians. Always bring the workpiece hole to the correct pre-reamed diameter before using this tool, leaving only a small amount of stock for the reamer to remove. Secure the shank fully in the chuck or collet before spindle engagement, and confirm spindle rotation direction matches the right-hand cutting geometry. Never reverse a reamer under power, as this will damage the cutting edges.
