Hertel 72012107 Chucking Reamer 0.1210 in Hss 4 Flute

Product Description

The HERTEL 72012107 is a high-speed steel (HSS) chucking reamer designed to produce accurate, smooth-finish bores in metal workpieces. With a reamer diameter of 0.1210 inches, an overall length of 3.5 inches, and a flute length of 0.875 inches, this tool delivers precise hole sizing in production and maintenance machining applications. The bright, uncoated finish suits general-purpose ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, making it a reliable choice for machinists and tool-room technicians who require repeatable dimensional accuracy in small-diameter holes.

This chucking reamer is suited for use on drill presses, lathes, and CNC machining centers where close-tolerance hole finishing is required. The right-hand cutting direction and four straight flutes are well matched to through-hole and blind-hole reaming in production-run and one-off repair scenarios. It fits into workflows that require moving a drilled hole to a precise final diameter, including fixture work, jig assembly, and component repair in industrial maintenance settings. A single unit is the minimum order quantity, making it practical for both shop stocking and individual job needs.

Key Features

• 0.1210 inch reamer diameter for precise small-bore hole finishing
• High-speed steel (HSS) construction provides hardness and wear resistance across common workpiece materials
• Four straight flutes with right-hand cutting direction for smooth, consistent material removal
• Straight-cylindrical shank for direct mounting in standard drill chucks or collet holders
• Bright, uncoated finish — no coating buildup risk on tight-tolerance cuts
• 3.5 inch overall length with 0.875 inch flute length suited to shallow and moderate-depth holes

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers accepting a straight-cylindrical shank; falls within the 0.1000 to 0.1499 inch decimal inch reamer diameter range.

Installation Notes

Installation and use should be performed by qualified machinists following standard shop safety practices. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Always bring the workpiece to a pre-drilled undersize hole before reaming — never use this tool as a primary drill. Cutting fluid appropriate to the workpiece material is recommended to extend tool life and maintain surface finish quality.
