Norseman 12271 CR-4FS Set FS Reamer

Description

• Material: Constructed from special Hi-Tungsten tool steel (also referred to as high-speed steel) for durability.
• Finish: Features a gold oxide surface treatment on the body and clearance for maximum lubricity, which helps to reduce friction and heat during use.
• Design: The reamers have a fast spiral flute design (Type 51-AG), which is more aggressive than standard spiral reamers and helps to eliminate the tendency of the tool to pull itself into the hole. They are constructed with a left-hand spiral and right-hand cut.
• Shank: Each reamer features a tri-flat shank to prevent slippage in the drill chuck, and a 1/2″ reduced shank with a stop collar.
• Set Contents: The set includes four reamers in fractional sizes: 3/8″, 1/2″, 5/8″, and 3/4″.
• Intended Use: These tools are specifically designed for reaming of tough materials like structural steel plates commonly found in truck frames, rail cars, bridges, and pressure vessels.
• Origin: Manufactured in the USA with globally sourced material.
