Hertel 2291110 Chucking Reamer Size 11 Hss 6 Flute

Product Description

The HERTEL 2291110 is a straight-flute chucking reamer designed to finish-ream wire gauge size 11 holes to a precise 0.1910 inch diameter. Built 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 straight-cylindrical shank seats securely in a drill chuck or collet holder, and the 6-flute geometry distributes cutting load evenly for smooth surface finish. At 5 inches overall length with a 1.25 inch flute length, this is a compact, rigid tool suited to short-reach reaming operations on the drill press, lathe, or CNC machining center.

This chucking reamer is used in machine shop, maintenance, and production environments wherever a wire size 11 hole must be brought to close tolerance. Typical applications include reaming drilled holes in steel, aluminum, brass, and cast iron components. Right-hand cutting direction makes it compatible with standard spindle rotation. Machinists, tool and die makers, and maintenance technicians reach for this size when drilling alone does not achieve the required hole quality or dimensional accuracy.

Key Features

• Wire size 11 designation, 0.1910 inch finished diameter for precise hole sizing
• 6 straight flutes distribute cutting force evenly and promote clean chip evacuation
• High-speed steel (HSS) construction handles a broad range of workpiece materials
• Bright, uncoated finish — ready to use as supplied, re-sharpenable
• Straight-cylindrical shank for reliable seating in standard drill chucks and collet holders
• Right-hand cutting direction, compatible with conventional spindle rotation

Compatibility

Designed as an OEM-style machine reamer for use in any drill press, lathe tailstock, or machining center spindle that accepts a straight-cylindrical shank tool in the 0.1910 inch diameter range.

Installation Notes

A licensed machinist or skilled technician should secure the shank firmly in the chuck or collet before use and verify runout is within acceptable limits. Always pre-drill the hole close to final size and apply cutting fluid appropriate to the workpiece material before reaming. Power down and lock out the spindle before changing or adjusting the tool. Do not attempt to ream a hole that is more than a few thousandths undersized, as overloading the flutes will accelerate wear and reduce hole quality.
