Hertel 72308265 Chucking Reamer Size 26 Cobalt Steel

Product Description

The HERTEL 72308265 is a wire size 26 chucking reamer designed to finish-ream precision holes to a diameter of 0.1470 inches. Built from cobalt steel with a bright, uncoated finish, this tool delivers consistent sizing performance in harder workpiece materials where high-speed steel tools fall short. The straight-cylindrical shank seats securely in drill chucks and collet holders. With 4 straight flutes and right-hand cutting direction, it produces clean, accurate bores in a single pass. Overall length is 4 inches with a 1-inch flute length, making it well suited for shallow-depth reaming operations in production and toolroom environments.

This reamer is intended for machine shop, toolroom, and production floor use where hole finish and dimensional accuracy are critical. It is applied in drill press, CNC machining center, and lathe operations requiring tight-tolerance through-holes or blind holes at the wire size 26 diameter. Machinists and tool-and-die professionals specify cobalt steel reamers for stainless steel, alloy steel, and other abrasion-resistant materials where standard HSS tools wear prematurely.

Key Features

• Wire size 26 diameter: 0.1470 inches for tight-tolerance hole finishing
• Cobalt steel construction resists heat and wear in hard or abrasive materials
• 4 straight flutes with right-hand cutting direction for smooth, consistent stock removal
• Straight-cylindrical shank for secure chuck or collet mounting
• Bright, uncoated finish — no coating buildup to affect tolerances
• Compact 4-inch OAL with 1-inch flute length suited for shallow reaming operations

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool with a drill chuck or collet holder accepting a straight-cylindrical shank at the wire size 26 diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists using drill presses, lathes, or CNC machining centers. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use and verify runout before cutting. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Remove chips frequently during blind-hole operations to prevent packing and tool breakage.
