Hertel 2350171 Chucking Reamer 17/64 in Hss 6-flute

Product Description

The HERTEL 2350171 is a high-speed steel (HSS) chucking reamer designed to produce accurate, finish-quality holes in metalworking applications. With a 17/64 inch (0.2656 inch decimal) diameter and a 6-inch overall length, this reamer features a 1-1/2 inch flute length, 6 spiral flutes, and a right-hand cutting direction. The bright, uncoated finish suits general-purpose ferrous and non-ferrous material reaming. It mounts via a straight-cylindrical shank for secure grip in standard drill chucks and collet holders. Machinists, tool-and-die makers, and maintenance technicians use this tool to bring drilled or bored holes to precise dimensional tolerance.

This chucking reamer is suited for machine reaming operations on drill presses, lathes, milling machines, and CNC machining centers. The straight-cylindrical shank provides broad compatibility with common workholding setups. It is appropriate for production and maintenance reaming of through-holes and blind holes where a close-tolerance fit is required. The 6-flute spiral configuration promotes smooth chip evacuation and improved surface finish compared to fewer-flute designs.

Key Features

• 17/64 inch diameter (0.2656 inch decimal) for precise hole sizing
• HSS construction provides durability across a range of workpiece materials
• 6 spiral flutes with right-hand cutting direction for smooth chip flow
• 1-1/2 inch flute length suited to standard depth reaming tasks
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright/uncoated finish — no coating compatibility concerns for most applications

Compatibility

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

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank fully in the chuck or collet and verify runout before reaming. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid for the workpiece material. Do not use this tool as a drill — reamers are finish tools and should only be used on pre-drilled or pre-bored holes close to final diameter.
