Value Collection SM0407090 Chucking Reamer Hss 0.709 in

Product Description

The VALUE COLLECTION SM0407090 is a straight-flute chucking reamer machined from high-speed steel (HSS) for precision hole finishing in metal workpieces. It carries a 0.7090-inch reamer diameter and a 9-inch overall length (OAL), making it suited for deep-reach finishing passes where dimensional accuracy is critical. The bright, uncoated finish supports use across a broad range of ferrous and non-ferrous materials without the heat-retention concerns of some coated tooling. A right-hand cutting direction and straight-cylindrical shank allow direct mounting in standard drill chucks, collets, and machine spindles with minimal runout. This reamer is intended for use by machinists and tool-and-die professionals on manual lathes, drill presses, and CNC machining centers.

This chucking reamer is appropriate for production and maintenance machining applications that require tight bore tolerances. The 2.25-inch flute length provides adequate chip clearance for through-hole and shallow blind-hole reaming operations. Its straight-cylindrical shank seats reliably in drill chucks and ER collet systems commonly found in vertical machining centers and turret lathes. Applications include bearing seat finishing, bushing bore sizing, and precision dowel-pin hole preparation in general metalworking environments.

Key Features

• 0.7090-inch reamer diameter for precision bore finishing
• 9-inch overall length for extended reach in deep setups
• 2.25-inch straight flute length aids chip evacuation in through-holes
• HSS construction provides good toughness across common workpiece materials
• Bright uncoated finish suits general-purpose ferrous and non-ferrous applications
• Right-hand cut with straight-cylindrical shank for standard chuck and collet mounting

Compatibility

Designed as a general-purpose chucking reamer compatible with standard drill chucks, ER collet holders, and straight-shank toolholders used on drill presses, manual lathes, and CNC machining centers.

Installation Notes

A licensed machinist or qualified toolroom technician should install and operate this reamer. Always ensure the machine spindle is fully stopped and the workpiece is securely fixtured before mounting or removing the tool. Verify chuck or collet runout with a dial indicator before taking a finishing pass, as excessive runout will compromise bore tolerance. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
